Software :: ALSA And PulseAudio - Recording Multiple Input Devices?

Apr 28, 2011

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.

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.

Ubuntu Multimedia :: Skype On Ubuntu 10.04 - Sound Devices - Recording Is "PulseAudio Server (local)" - Doesn't Work

May 22, 2010

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?

OpenSUSE Multimedia :: Output One Playback Stream To Multiple Devices Simultaneously With The Current PulseAudio / Phonon Setup?

Jun 9, 2011

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.

General :: Su -c "yum Remove Alsa-plugins-pulseaudio Pulseaudio" - Distribution With No Pulseaudio?

May 22, 2011

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 ?

Ubuntu Multimedia :: Recording Audio From Alsa Sound Card

Sep 26, 2010

I posted my question on Linx.com, but have not received an answer after 75 viewers to my question:
Ok my respected Linux genius. This is my project. First I have a Windows / Linux combo OS set-up!
In my windows, I use the latest realtex sound driver as this gives me complete control with recording output control and Microphone gain control. In the set-up, there is a stereo mixer component with is necessary to engage the direct sound recording from my sound card. To make this all come together, I use a sound recording software [ free sound recorder 9 ] and to convert the recording to a wma, wav, or meg, I use Roxio 10 to produce audio cd's to play on all CD Players.

The challenge for me in Linux is to create the same set-up with Linux applications to produce the same professional results.Presently, my kubuntu 10.04 has Alsa sound drivers, with a version of realtek incorporated. I have the Alsa mixer software as well as Audacity as the sound recorder program. But no matter what I do, audacity depends on the microphone to record, which makes the final recording pure crap. If I lower the microphone boost or gain in my Alsa mix, then Audacity can not record the ambient sound from the speaker output and it will only recognize mono and pulse as the sound method. With the pre mention set up, Who has a set up identical to what is offered to windows that will do exactly the same for Linux. I basically want to record directly from the sound card in my Linux, without depending on using my microphone and then a CD burning program to make the conversion to MPEG or the necessary file format for the burned CD to play in all CD players, not just on a PC) I am trying to stay away from command line language in the terminal. I really need a replacement for Audacity,cause Free Sound Recorder is made for Windows Platform......I need a Linux sound Guru for the answer.I am not doing this to pirate music....I have over 3,450 music track inside my Rhapsody subscription and I like to record music for personal listening on my portable CD player and at 0.99 per track charge to do this in Rhapsody, I might as well by a recording studio and hire the singing artist.Basically in short..I need to know if there is a setting I can engage in my Alsa Mixer panel that will allow me to record directly from my sound card without using my microphone as a default. When I mute the microphone in my Alsa control panel, my Audacity program will not record using the microphone, which I do not want to use anyway. I just want to record straight from my sound card, as this eliminates all hiss, distortion that is inherited with using a microphone.

Debian :: PulseAudio And ALSA - How These Two Interact

May 8, 2011

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?

General :: Recording Sound From TV Tuner Card Thorough Alsa Driver On Ubuntu

May 28, 2011

I have a TV tuner card with its output connected to the CD in of an integrated sound card. Video is OK, and the sound also gets thorough (to the line out) when running xawtv, for example. However, I found no ways yet for recording it.I'm running Ubuntu 10.10 with ALSA drivers. Pulseaudio was running in the beginning, now it doesn't, but it doesn't seem to make much difference.

capturing with VLC, using plughw:0,0 as the audio capture device. (Result: no sound track at all in the resulting video.)arecord, then aplay.alsamixer. The capture source is set to "CD" (and on the input side it's also "CD" where I can effectively modify the volume for audio going through...), but still no result.

Debian Multimedia :: My Sound - ALSA Or Pulseaudio?

Jun 18, 2010

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?

Debian Hardware :: ALSA - PulseAudio And Microphone On An Audigy2

Sep 22, 2010

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.

Ubuntu Multimedia :: Lost Simultaneous Use Of ALSA And PulseAudio?

Nov 7, 2010

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.

Debian :: Installed/removed Pulseaudio - Lost ALSA

Jan 8, 2010

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?

Ubuntu Multimedia :: Midi With Alsa Oss Emulation And Pulseaudio?

Sep 15, 2010

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.

Fedora X86/64bit :: No Sound From Pulseaudio , ALSA After 2.6.40 Kernel Upgrade / Get That?

Aug 2, 2011

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?

Debian Multimedia :: No Microphone Recording But Input Does Works In Some Way

Aug 12, 2011

For some time, my microphone input doesn't reach the recording application, but instead goes directly to the loudspeaker. If I make a sound in the microphone, it will go to the loudspeakers, and Audacity or Skype will not "hear" anything (and of course, with this set-up, there's a constant noise in the loudspeaker, coming from the microphone).This problem goes away if I install PulseAudio. So obviously, there's nothing broken with either of ALSA or hardware, only some misconfiguration somewhere, and PulseAudio can make a sense of the mess. Playing with all sorts of configurations in Alsamixer didn't help.

Unfortunately, I don't want PulseAudio, because it causes output problems which are a bit too subtle for me to describe coherently here. So I'd rather fix ALSA than Pulse.Please direct me into how to investigate this. The OS is Debian Unstable, the audio card is an integrated Intel ALC1200.

Debian Multimedia :: Alsa, Pulseaudio, ION2 & HDMI Sound Output?

Apr 29, 2011

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.

Software :: Pulseaudio Default Devices Overidden?

Aug 28, 2010

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)

Ubuntu Multimedia :: Make Pulseaudio STOP Copying Mic Input To Main Output?

Nov 26, 2010

I have a headset microphone plugged into the built-in audio input. The output is plugged into an amplifier > speakers.

Pulseaudio is "helpfully" routing the microphone input signal to the speaker output. I do not want this. I go to pavucontrol and disable the "monitor of the internal audio analog stereo" -- and what I say into the microphone is still coming out of the speakers.

Google gives a lot of information about how to live-stream mic input over the Internet. And, I found this here (that's for karmic, I'm running lucid):

[URL]

... but that's about how to ENABLE loopback. It says loopback should not be enabled by default, but I very clearly hear that something is doing the same thing as loopback.

(Of course, I need to hear sound from applications that are playing, and when I'm dictating text into NaturallySpeaking running under virtual box, I need sound input to go there -- so turning the mic all the way down to zero is not the solution.)

I'm fairly sure I remember hearing this behavior ever since installing Ubuntu, and I didn't do anything to turn it on. I can't imagine most users would prefer this behavior -- if it's the default behavior, why? It makes absolutely no sense to me. (Sorry. It's one of those piddly little configuration things that costs a couple of hours of web searching time, and after a while I just have to give up, but not before becoming much more frustrated than I should have to.)

So, to be clear, here's what I want:

- Applications playing audio should send sound to the main output.

- Applications receiving audio input should hear the microphone.

- Microphone sound should not EVER go to the main output unless I have explicitly launched an application making the connection. (The signal goes input -> output even when NO application is open - hence my consternation.)
