Ubuntu Multimedia :: Skype Can Only See Pulseaudio But Not Alsa Devices
Feb 26, 2010
i am having a problem with skype that i wasn't having before, and afaik skype hasn't been upgraded recently, so something else presumably has changed.
because of driver issues i have to use an external usb audio interface to do voip. this interface is not connected to the pulseaudio server. i am able to connect it to jackd and it works fine for both audio in and out. however it no longer shows up in the list of sound devices available to skype. this used not to be the case. i have tried stopping and restarting skype, as well as unplugging and reattaching the interface. the interface does not show up in pulseaudio manager in the lists of devices.

I have an Intel HDA audio card, and would like to record both my soundcard output and my microphone input at the same time. Getting to record my soundcard output (aka "Stereo Mix" or "What-U-Hear") is impossible for my soundcard without using the PulseAudio monitor, so I've set that up. Now I can record either the PulseAudio monitor for my soundcard, or the microphone input, but I don't know how to record both at the same time.
Currently, my .asoundrc looks like this:
Code:
pcm.pulse {
type pulse
}
ctl.pulse {
[code]....
So now I can choose either "pulse" as an input channel in, for example, Audacity or RecordMyDesktop applications (and then set in the PA volume control the actual channel which I want recorded), or choose "pulse_monitor" or "pulse_mic", in order to record either the PA monitor or the microphone, respectively.
I've read through the ALSA plugins reference, as well as the Asym and Dmix pages on ALSA wiki, but I'm still not sure how to put this together. I figured there should be a way either to route the microphone input into the ALSA output, and thus make the PA monitor "hear" what I speak into the microphone, or to make a completely new channel with both ALSA output and microphone input as "slaves", and then use that for recording.

I just installed skype 2.1 beta 2 (the deb file) from the skype website, but the only option I see under Sound Devices -> Recording is "PulseAudio Server (local)" This doesn't work for me, as the skype test calls don't actually record anything I say. I use skype a lot and FINALLY got it working under karmic, but I needed to upgrade to lucid and now it's broken.
When I open Sound preferences and look at the Applications section, Skype shows up as recording when I run its test call... but no sound is recorded? How is it possible that my sound card picks up something recording but doesn't actually record it when I'm in skype?

Due to the fact that with pulseaudio it is impossible to change the microphone/speaker/ring devices in skype, I had to remove pulseaudio.
After that I can choose a device in skype, but the mixer does not work anymore. There is a way to have a working mixer without pulseaudio package or a way to choose audio devices in skype with pulseaudio installed?!

i am using ubuntu 10.04 lts "lucid lynx", and has been encountering problems with audio recently.
i found out for some reason that my system fails to produce sound through pulseaudio, especially when an application is using it (e.g audacious).
the details of the problem:
1. i am using the pulseaudio equalizer from the repository, and i set a program (e.g. audacious) to use pulseaudio so that i can activate the equalizer.
2. while playing, all of my other applications lose the ability to produce any sound, and changing back to alsa during playback (which is using pulseaudio) in audacious indicates that the device is busy. examples include the loss of sound while playing a video from videos.
rough breakdown of what i want to (be able to) do: have sound for all applications using it, for example being able to play a video in videos from my browser and play music in audacious simultaneously.
is there a workaround for this? i'd like to think that there is, but so far my search returned nil.

I'm under Ubuntu 8.04 LTS Hardy Heron using pulseaudio. I've got 2 soundcards : one internal AC97 7.1 without midi (card 0 in ALSA) and a PCI C-MEDIA 2.1 with OPL3 midi (card 3 in ALSA) I have sound in most ALSA or OSS applications with full 7.1 + 2.1 duplex. I have MIDI playback in any ALSA MIDI players (client 29:0 in ALSA).
I'm trying to run Final Doom for W95 on WINE with OSS driver. I have sound effects but no MIDI music. I tryed with padsp and aoss wrappers. I know I can use ALSA driver in wine or timidity, but I would rather use padsp + hardware MIDI if possible. How do I configure ALSA OSS emulation for MIDI playback and check that it's working ? I tryed playmidi but whatever I told it, it couldn't find any midi device.

I am using a couple of Debian Distro (Sid and Lenny) add some Ubuntu into the mix. I made the switch because I was amazed and satisfied with Debian --> once installed, everything works. For me that's okay for o so many years now. I don't question a lot because it just works and I do my job on it satisfactorily. Namely programming the LAMP style programming. Lately I have been using Debian to communicate over the internet -- using Skype and Pidgin and other such things, not to mention listening to music, watching movies, just using the default applications when I originally install Debian.
Along the way, I need to configure something -- that is desktop related -- like the screen resolution of a new LCD monitor replacing the old one and such. Now about my sound -- I'm not touching it because it is working. But that is not the case always. Now I have a constant error -- it is irritating. Rhythmbox don't make a sound always when I have open a web browser (iceweasel, chrome, epiphany) and a site with multimedia object on it -- like a video or something. So how do I correct this? How do I know, too what I am using -- ALSA or Pulseaudio?

I've had nothing but trouble with Pulseaudio in Fedora 14. I had managed to get rid of it in Fedora 10 with the command: su -c "yum remove alsa-plugins-pulseaudio pulseaudio" I just don't want to have to deal with Pulseaudio anymore. It does not like my sound card and gets in the way. Is there a Linux distribution that does not use Pulseaudio ?

It was recommended to me that I remove pulseaudio and re-install alsa. All the howtos on reinstalling alsa had instructions for re-installing alsa from the source. Is it possible to re-install alsa from the repos? If so what are the necessary packages that I need to install, for a complete re-install of alsa?

I spent a few days trying to make audio work on my TV connected via HDMI to a PC. The speaker test used by the sound preferences was dead, as was MPlayer. I managed to find a solution for MPlayer, giving the option "-ao alsa:device=hdmi", as specified in this article:So, basically ALSA can see all my devices. This is the output of aplay -l:Quote:

Just upgraded to Lucid (32bit), pulse generally seems to work ok: I get sound out, I can see various apps connecting via the Sound Preferences dialog (audacious, flash via alsa interface, etc.), and my mic seems to work fine too.
However, when starting skype (v2.1.0.81 which defaults to pulseaudio if it's running), it isn't able to output any sound and I never see a connection appear in Sound Preferences. Don't really want to force it to use Alsa or anything like that; I'd be fine with pulse if it would just work.
I've tried installing the .deb from the skype site as well as the official ubuntu package, with the same result. Any idea why pulse seems to be working, but skype can't seem to use it properly?

I'm having a problem all the sudden with amixer. set Master 5% used to control the pulse audio master volume. Suddenly, it will only raise and lower the headphone volume. Pulseaudio works, but I no longer have a master volume at all.

I have recently acquired a Lenovo Q150 machine and attempting to use it as a HTPC. I've been reading that with this platform a newer kernel is required to make wireless, sound and a few other tweaks work correctly--so I bumped up to testing repositories to upgrade to the 2.6.38 kernel.[URL]...
The audio on this device has been more than a pain. I'm currently using XBMC to play media on this device and after setting the outputs to custom: plughw:1,9 sound is played correctly. I found this out by using alsamixer, selecting the sound card with the F6 key (Nvidia 1) unmutting all outputs, quiting, and running speaker-test -D plughw:1,X where X is the sub-device from the output of aplay -l until sound could be heard from the receiver.
Now my problem is that applications like mplayer, and iceweasel won't output any sound. I'd prefer not to use the optical out on the device and would like to send sound over HDMI. Has anyone had any luck getting it to work as it should?
I've also installed pulseaudio, not too sure if this is really needed. I've also used module assistant before upgrading to compile alsa from source, it worked but i just decided to upgrade the kernel instead of dealing with m-a every time an update comes through.

I recently upgraded to 11.4, but skype seems to mute all other application streams when a call is active. I can manually unmute them, but it is rather annoying especially when listening to music in the background using Amarok since everytime a new track starts it creates a new stream and is muted again.
I installed pavucontrol just to see if it had more options then kde's built in multimedia settings, but it doesn't (just has the cool how loud is the volume currently). I like the individual application (stream) volumes.

When using Skype, the sound suddenly stops working, both ways (about 4-5 min into the communication). The message "connection failed: connection terminated" is displayed and when I click OK, Pulse Audio closes and Skype freezes. Actually, and I just realized this, the sound suddenly stops working on Firefox as well. (The Alsa plugin in Pulse Audio 'Playback' just disappears). However this occurs after a long period of use. I've just watched about 30 continuous minutes of live soccer through Espn3, before the audio stopped working. No message was displayed though, and just refreshing the page fixed it.
All this makes me think this is some type of Alsa-Pulse Audio problem. I really don't understand well what they are, although I believe Alsa is a driver and Pulse Audio a sound server? Sorry, I started using Linux very recently. I am using Ubuntu-Studio 10.04 and the rt Kernel (2.6.33-29-realtime). Sometimes I use Pulse Audio in Jack and vice-versa, using pactl load-module module-jack-sink and source respectively, but my problem seems to occur even if I unload the modules before using Skype. I believe all this started happening after I started using the rt kernel and/or the module-jack-sink/source.

Is it possible to output one playback stream to multiple devices simultaneously with the current PulseAudio / Phonon setup? The PulseAudio mixer only has radio buttons to choose one device per playback stream. I believe the hardware is capable of this, since I remember doing that before we had PulseAudio. How can I duplicate an audio stream?
Here's one application scenario: I am travelling with my family, all crammed in small hotel room. My wife and me want to watch a movie on my laptop without waking up our kids. I just happen to have one analogue headphone available and one wireless USB headset with me. (Of course, the low tech solution is to bring an 3,5mm Y-cable to attach two analogue headsets, but I would really love to use the USB headset together with the analogue one.)
Another similar thing that bugs me is that my laptop's built-in speakers now always seem dead when an analogue headphone is plugged in. This is mostly what one wants, and before PulseAudio, one had to manually switch them off which was generally annoying. However, the downside is for example with notifications.
For example, before PulseAudio, I could configure Skype to always ring over the laptop's built-in speakers, regardless of whether the analogue headphones were plugged in. This is no longer possible, since PulseAudio does not distinguish between built-in speakers and built-in analogue port any more, while old Alsa did. So in my office, where some analogue headphones are plugged into the docking station, I never hear Skype ringing if I don't wear the headphones.

When I installed my 64 bit system of Ubuntu 10.04 the sound worked very well and I were very happy. The problem started however when I installed Skype which uses pulseaudio. As soon as I start skype (or any other application that uses pulse, HoN for example) the applications sound output or input does not work at all. If I have pulseaudio started in some way, applications that I suppose do not use it like spotify or flash player stops to produce sounds. And when I type "pulseaudio" in the terminal it gives me this:

I'm using XFCE with pulseaudio. I don't have a keyboard with dedicated multimedia keys. Getting to alsa to work with f1 f2 and f3 (mute, volume down, volume up) was easy. I want to use pulseaudio instead of alsa. What do I use for mute, volume up and down?

Is there a way to just temporarily disable pulseaudio and use alsa instead?
Or run a program under alsa while letting pulse sit in the background?
I'm getting sick and tired of not being able to play any platinum games on wine...

Regarding ALSA and PulseAudio - Explanation on how these two interact. After installing Debian I realised that my sound control (Volume Control: HDA Intel ALSA mixer) was different from what I had with Ubuntu where it would display a window called "Sound properties" in which allowed me to control the sound of each program running - I believe this is the PulseAudio aspect. (If I'm wrong at this point please correct me)
Now I have managed to get PulseAudio setup correctly for me (not as easily as Ubuntu but I moved to Debian to learn, not be spoon fed), however the way in which I did it may of been wrong - pretty much just went to synaptic and installed everything with PulseAudio in its name
Currently the sound icon in my top Gnome panel (within the notification area applet) has the ALSA mixer, sometimes when I log on it has the PulseAudio one (Sound preferences window), I don't really mind which one is loaded thanks to the PulseAudio Volume Control program (under Sound & Video). Is there a way though to stick with just one?

I've recently switched to Debian Squeeze x64 from Kubuntu 10.04 x64. Overall, I like Debian.
I have one small problem: I play Runescape occasionally, which requires Java. On Kubuntu, I'd use Sun Java, however on Debian it just crashes.
So, I decided to use OpenJDK. Now OpenJDK works fine... But I can't get it to work with ALSA audio output. I installed PulseAudio, and that took care of -that- problem.
Now, currently I have both ALSA and PulseAudio installed. For playback, it works great. PulseAudio is a bit laggy, which isn't too noticeable in Runescape, and for things like media, it seems to work OK. For TF2, which I play through Wine however... No. So, I set that to ALSA, and -that- worked right.
Now comes my main problem: I can't get mic input. I'm trying to use Teamspeak 3(proprietary), and while audio output works, I can't get any input.
TS3 lets me use ALSA or Pulse(along with a couple more), but:
1. Selecting PulseAudio lets me select "SB Audigy Analog Mono", the same thing but a "monitor", and "Default Input Device". None of those work, I get "Error: could not open the selected capture device". On top of that, in the PulseAudio control panel, I get zero level on the monitor, making me think its not setup correctly.
2. Selecting ALSA gives me a whole list of options... But they appear to be audio -outputs-, not capture devices. Also, I get the same error as above.
When running "arecord -l", I get:
Of these, I believe the first one was what worked on Kubuntu. Now, of note is that I'm using my "Line in 2" port for capture; On my previous installations I'd simply set its volume with alsamixer and be done with it.
That all being said, I need a solution to one of these three problems:
1. How can I get OpenJDK to work with ALSA, and thereby remove PulseAudio; get everything standardized with ALSA like I had on Kubuntu, OR
2. How can I remove PulseAudio lag, and get the mic working with that, remove ALSA and get everything standardized with PulseAudio, OR
3. How can I simply make my mic work with the current setup?
Any of those will do. I just need to get my mic working.

At one point, I thought I needed pulseaudio for sound, so I messed around with installing it, even though at the time I had ALSA installed. (suffice to say, I know very little about linux sound). Pulseaudio never did work, I removed it with aptitude. But now ALSA seems to reach to pulseaudio for some reason.
Code:
More confusing is that there are no "alsa" looking processes in ps -A. But apparently, the basics are there
Code:
There's only one thing in init.d that seems relevent to alsa:
Code:
But doing this does not help anything. Does anyone know what to do from here?
And because I'm curious, how come I get sound from Flash Player and Audacity with no problem?

I just got the upgrade for the Linux Kernel version 2.6.40-4 on my Fedora 15 x86-64 box today, and the installation completed with no problems. However when I rebooted after doing the upgrade, I noticed that I had no sound. I use an ATI Radeon HD 4350 video card, and the opensource ATI driver, and use the HDMI audio from it for sound, since my monitor has a sound output jack on it. I've booted into the previous kernel (2.6.38.8-35), and sound works fine. I've tried with the new kernel in both KDE (my default desktop environment) and XFCE to get sound, and it does not work in either one. I've tried installing the VLC Phonon Backend instead of the GStreamer Backend, reinstalling Pulseaudio, reinstalling Alsa, modprobing the necessary modules needed for the card, checking all configurations with the available Pulseaudio tools (paprefs, pavumeter, pavucontrol), checked the volumes using alsamixer, and reinstalling the ALSA Pulseaudio plugin. After trying all of these, I can still get no sound out of any application, and I also noticed that Flash video plays at 2-3 times it's normal speed after the upgrade. Again, these problems do not occur on my previous kernel. Did I maybe overlook something, or can anyone else think of something I could try?

I am using 8.04, Pulseaudio, Microsoft Lifechat USB headset and Skype on a Compaq 210. Pulse works fine for everything else. One day, it just stopped working for no apparent reason (only on the Skype mic) so I uninstalled and went back to ALSA (for a few reasons) but couldn't get that working either so now back to square one. When I boot Skype, all goes well, can place a test call, no errors. But on playback of the message it's pure fuzz, basically white noise, no sign of my voice. I've twiddled with just about every volume control and toggle I can find and then some, but nothing. Another interesting thing; Pulse is now NOT working unless I input 'pulseaudio -D' in a terminal after boot. Then it seems to be okay, 'cept the mic.
Strange as the mic works perfectly and crystal clear in Sound Recorder. No probs. So:
1/ How do I replace the recorded white noise in a Skype test call with my own mellifluous tones and;
2/ Where do I put 'pulseaudio -D' (what file) so it will be read and turn pulse on at boot?
Using Skype 2.1.0.47 (I know there is a newer version, .87 I think, but that was even more problematic). Another strange thing; the newer version (.87?) worked flawlessly for months before the mic just one day died (ONLY in Skype). As explained on my last thread; wife's uni/entertainment machine and me being the house computer dude, one of the reasons we use Linux is so I am not fixing Windows problems constantly. I only go near this machine when something goes pear-shaped so that is rarely. My wife doesn't tweak with her computer AT ALL.
Sound issues on this machine have been pretty much constant and I am really sick of it. I have two desktops running ALSA and Skype flawlessly with any USB headset AND they can ring incoming calls through the external speakers and you can take the call through the headset, something that is seemingly impossible for some reason in Pulse. Despite its bells and whistles, this is a serious oversight by Pulse developers in my opinion. (Unless I'm missing something and I've have searched for hours trying to fix THAT little mystery).

I shall try and keep it short. Under Sys->Prefs->Sound I have selected pulseaudio server for input and output. Under Pulse-Audio manager->devices I can see the motherboard, a usb webcam, and my new soundcard. I edited the ~/.pulse source and sink files to match the new soundcard (alsa_output.pcixxxx_alsa_playback_0 and so on) under PulseAudio manager_> modiles the id numbers match the right info in the /proc/asound/cardX/pcmi0/info files
Under pulseaudio volume I set the default input and output to be the new soundcard. But in pulseaudio volume control I can see the USB webcam is still the input, and any sound still gets output to the motherboard. Is something overriding pulseaudio, or have I missed something. (The motherboard mic socket is broke, and the USB mike isn't good enough so I really need to get the soundblaster Audigy SE up and going)

I've got Karmic installed on a MacBook, and I'm trying to get Skype up and running. I've already patched the iSight firmware, so the the webcam itself works fine, but I have no microphone support. If I go to Sound Recorder, the microphone picks up my voice fine, but not Skype. In the Skype audio settings, all are set to Pulseaudio server (local), and that is the only selection available.

I installed skype 2.1 beta and pulse audio. Just installed the packages and it worked. Surprisingly. Problem is that Skye now selects pulseaudio for microphone, out and ringer. No problem it actually set it up to my logitech headset which is by default almost right. It set it up to use my logitech microphone and headset speakers for talking, which is great. But I want to switch my ringer from headset speakers to main computer speakers. Anyone know where this can be done. Skype only lets me select pulseaudio (locla server) for all three. Yet somehow it knows to use my logitech headset for talking. But I want to direct my ringing of incoming calls to main speakers. pavucontrol does not let me do this. Anyone has an idea of how to do this? If there is a graphical application that can do this, please let me know.
Used ubuntu for years and loved it. recent bugs in flash and loggin out and others made me try debian for extra stability and security at the risc of loosing myself in the complexity of debian as it's no plug and play here. So far seems to be very similar in use to ubuntu, surprisingly. Running nvidia-xconfig seems to be the only difference. So far I have been able to figure things out to make it work, we will see how I do in the long run. Ubuntu was sure easy.
