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.

Ubuntu Multimedia :: PulseAudio Won't Acknowledge Flash As A Playback Stream

Mar 12, 2010

I'm running 64-bit Karmic with the native 64-bit Flash plugin (not the 32-bit plugin with a wrapper).Before now, I had to pick between streaming music on Gnome or streaming music from Flash. In other words, if I was listening to music in Rhythmbox or Totem, I'd have to close all those sources before playing a flash video or else the sound wouldn't work. Likewise, if I was playing a flash video and wanted to listen to music in Rhythmbox or Totem, I'd have to close Firefox from the system monitor.

So I installed the PulseAudio Device Chooser, following all the instructions in this thread. Now I can't get any sound from Flash at all, but I can play as many Rhythmbox and Totem streams as I want at the same time. In the "Playback" tab of the PulseAudio Volume Control, Flash is never acknowledged as a playback stream.

Ubuntu Multimedia :: VLC / Phonon Randomly Drops Audio Stream

May 24, 2011

I have an Asus EEPC that I use in my classroom whenever I want to show a movie. I normally keep all of my educational videos as ISOs, and then simply move one over to the netbook when needed. I normally use VLC for playback. With the latest upgrade, however, I'm having a few difficulties. No matter what DVD I choose to show with VLC, the audio stream will randomly drop every 10 minutes or so whenever I am using KDE as my desktop environment. In order to re-enable the audio stream, I have to either completely stop playback OR reconfigure the audio output in VLC.

(It does not matter if I change it right back to what it was, I will get audio for another 10 minutes or so). I've also noticed that if I pause playback, sometimes the audio will not re-enable when unpaused. Strangely, however, I do not have this behavior at all when I'm using Gnome as the desktop environment. I get seamless audiovisual playback and never have to fiddle with the audio. Is this a documented problem in Phonon somewhere? How I might better backtrace what's going on?

Debian Multimedia :: Sometimes Phonon Is Listing So Many Devices

Aug 2, 2015

I've encountered this problem twice. Sometimes Phonon is listing so many devices like this: [URL] ....

Usually there are just two devices like this: [URL] ....

When there are so many devices listed the volume control by using volume keys is different. It's usually up or down by 5%, but if the condition is like that the volume not up or down by 5%.

I've never encountered this kind of problem in other KDE distros. I'm using Jessie.

Ubuntu Multimedia :: Cannot Run Jack And PulseAudio Simultaneously

Jan 10, 2011

I'm on Ubuntu 10.04 64bit, and I've got JACK and Pulseaudio both installed, though I don't run them simultaneously. I also have LinuxSampler and Rosegarden, and I have the necessary ALSA drivers. Pulseaudio can output to my external sound card, but JACK doesn't, even if I tell it to. I've seen its full name (Guitar Rig Mobile IO) and chosen it as the output device under Settings, but to no avail. It still sends the output to the internal (and crappy) sound card.

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:


pcm.pulse {
type pulse
ctl.pulse {


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.

General :: File Output Redirection - Redirect Stream To Multiple Files?

Dec 7, 2010

I'm working on some scheduled task script files to keep nightly backups of some of our database information in place, and it's a bit annoying when they blow up. I know how to redirect stdout and stderr to a flat file I can view when I come in, and I know that 2>&1 maps them both to the same file (whatever was named in 1). However, I'm running into some cron-time situations where it's easier to have the two streams together, and other cron-time situations where it's easier to have them separated. I can't really tell which is going to happen; is there some way I could create both kinds of output file for my scripts, so that I've got a std_err only file and an interleaved std_out/std_err file?

Note: I've looked at the 'tee' command, but I don't think it will work for what I'm after. 'tee' appears to only work with stdout; I'm trying to work with stderr.

I always keep my headphones as well as my 2.1 speakers connected simultaneously on my PC (Gigabyte motherboard). Both these audio devices work fine simultaneously on my Windows 7, but in Ubuntu, only my headphones work, speakers don't work at all. I tried changing some settings in SOUND PREFERENCES as well as ALSA SOUND MIXER, but not luck so far.

OpenSUSE Multimedia :: Worfklow - Photos In Sync Across Multiple Devices Without 3rd-party Services?

Sep 2, 2011

I *take* photos with both my Android smartphone and a fullblown DLSR. I *manage* photos organize, rename, rotate, etc. -- on my Opensuse box with KDE's Gwenview, and on my phone with Pixie Reef's "Fishbowl" Photo Gallery [URL]... I'm interested in your ideas about ways to keep everything in sync -- without using 3rd-party online services (No Picases, Flickr, Smugmug, etc). What needs to be kept in sync, somehow, includes:

The photos themsleves. Their organization among, and order in, various 'albums' Photo & filesystem metadata -- timestamps, filenames, EXIF data. PhotoApplication-specific data recognizing that at any time a change may be made on either device. rsync is a possibility, but once photos move into different dirs, it'd get messy. What workflow can I use to do this? Do I need a central server in the mix? If not using the 3rd-party services, is OwnCloud my best/only choice assuming that after each (group of)change(s) on each device I manage to sync with it?

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 :: 10.10 - Speakers And Headphones Output Sound Simultaneously?

Nov 1, 2010

I just installed 10.10 and I'm having an issue where sound outputs from the headphones and my speakers simultaneously, and the volume control controls both outputs rather than one of them individually.This has been asked about before at this thread, but none of the solutions I've tried from there have worked. I tried installing linuxant, but it just killed my sound altogether despite uninstalling it afterward. I tried updating the Linux audio modules as per this page but to no avail.I'm running Ubuntu 10.10 (64-bit) on my own custom built desktop, which for what it's worth, contains this motherboard.

Ubuntu Multimedia :: Multiple USB Mics To Be Used Simultaneously?

Nov 11, 2010

I recently purchased a set of three professional mics and converters for them (they are XLR mics, so i bought three icicles to convert into the USB port)The computer sees all three microphones, but I can figure out how to be able to record on all three at the same time.Is this at all possible, or did I just waste a ton of money on converters?EDIT: I would like to add that these mics are identical, and I'm wondering if nothing else if it's possible to merge the two mount points so that it appears as one micEDIT AGAIN: I have also just installed Pulse Audio Volume Control, and it picks up both mics. How can i tell audacity to use this?

Ubuntu Multimedia :: PulseAudio Lag With Simultaneous Output

Jul 1, 2011

I've got two soundcards in my new machine - Realtek ALC8892 onboard, with headphones plugged in, and an M-Audio Audiophile 192 with speakers. There's also HDMI sound out on the graphics card, but I don't use that.

Audio with PulseAudio's output through the sound card is fine. Audio with PulseAudio's output through the onboard sound is fine. If I set the output to Simultaneous Output, however, I get significant lag. Almost half a second. It's quite distracting.

Is this just a problem with PulseAudio's simultaneous output implementation, or is there a fix that I've overlooked? Running 64-bit Natty, btw.

Ubuntu Multimedia :: Pulseaudio Disabling Simultaneous Output?

Mar 16, 2010

sat in an internet cafe with my music on loud using my headphones when my cell phone vibrated and upon taking off my headphones I noticed that pulseaudio was channeling all my music not only to my headphones but also to my regular monitor out!

So I was actually listening to music using my headphones when in fact the sound was LOUD on my laptop speakers...

Is there a way to configure the thing to not do that? I want the sound to be muted as soon as I plug in my headphones.

Ubuntu Multimedia :: PulseAudio - Mute Mic Output Through Speakers

Nov 9, 2010

I don't want to monitor my inputs. In other words: My microphone input plays through my speakers, adding a lot of undesirable noise from the mic. I can mute the mic inputs in alsamixer and/or in the Pulse volume control. This works to get the mic out of the speakers--but it also mutes my mic entirely, so I cannot record audio or use Google Talk. I want the microphone muted in my output, but available to my apps.

(I try to get on the Pulse bandwagon but it is so hard--I thought this was exactly what it was supposed to do, give easy mixing control over inputs and outputs. But I have to search for "fixes" with every single Ubuntu release for two years now, ever since it was first included. Ok, venting over, time to get it working!)

Ubuntu Multimedia :: Redirecting Pulseaudio Output Without Padevchooser

Jul 30, 2011

Today I tried to use padevchooser on Natty to send my laptop audio to my home media machine (which has the good speakers) using the "default server" option. Turns out padevchooser doesn't work on Unity and the threads I have seen say it is deprecated for other gui tools,

So what is the easy gui way to switch from my local pulse server to another one on my LAN, without using padevchooser, or switching off Unity? Or is this a regression?

Slackware :: Current - Phonon Applications Silent - Muted ?

Jan 2, 2010

I have a very strange problem with Phonon. I am running slackware-current with KDE-4.3.4 on an old PC with CS46xx sound chip. The Phonon backend is Xine. The system is newly installed.

Applications which use the Phonon layer are silent or muted. I am not able to hear anything. Affected is for example Amarok, Dragon Player, Minitube or the Kde Notification system (when playing sounds). What makes the situation strange is the fact, that everything looks pretty fine:

Alsa works excellent and is configured correctly.
KMixer affects the alsa system settings as expected.
Mplayer works, Xine works, mpg321 works.
Inside Kde's system settings -> Multimedia, the Test button works and i can hear the Kde start up melody.
Inside Kde's system settings -> Notifications, the play button for sound events works and plays the given sounds.

The problem appears with a newly created user account, too.

What i also tried was to compile [url]. The output looks ok to me, too. No errors and ogg and mp3 support is available.

Last but not least i tried the Python coding tutorial at [url]. The fact, that this works, unsettles me totally.

Ubuntu Multimedia :: FFmpeg Unsupported Codec For Output Stream

I went to install libmp3lame-dev using
sudo apt-get install libmp3lame-dev

And it comes up with this:
The following NEW packages will be installed:

OpenSUSE Multimedia :: Disable A Sound Device In Phonon?

Jan 10, 2010

I have two sound cards active on this machine and they both work fine. However I would like to blacklist one card from being used for audio capture in KDE, because I am already using it outside of KDE for timed recording. The problem is that when I start amarok while timed recording is going on, it attempts to probe the card and this causes the recording to abort.

In Configure desktop > Multimedia, I can see the two cards. I can alter the priority but the Remove button is greyed out. So I can't remove a card from phonon.

Searching around for where phonon stores its configuration led me to ~/.config/ This certainly looks like the info I was trying to edit, but it's encoded in some way code...

How do I tell the xine backend to use the same vo as smplayer?

OpenSUSE Multimedia :: KDE 4 Phonon Xine-backend Configuration

Sep 6, 2010

So I have made an interesting Discovery with regards to using KDE4 Kaffeine version 1 and Dolby Digital 5.1. The basic problem seems that there is no way to configure the Phonon xine Backend in KDE 4 for use with Kaffeine version 1. There is however, a xine-config file located at:


There appears to be no GUI way to change the default xine configuration (for use with KDE 4 applications) and while you can do so manually, the options seem bewildering, at least to me.

When you run xine-ui or Kaffeine/KDE3 there is an option to adjust the xine audio configuration using a GUI. Any changes made here are ignored by KDE 4 applications. As luck would have it you can copy the old xine configuration (adjusted by Kaffeine/KDE3) over the new one for Kaffeine in KDE4. The old text file configuration is located at:


If you were to use the old Kaffeine/KDE3 to adjust your xine audio configuration and then copy this file to the Kaffeine Version 1 KDE4 location, those changes should be used by the new version 1 Kaffeine in KDE 4. After Kaffeine/KDE3 audio settings work as you desire, open up a terminal session and make the following file copy. You must overwrite or rename the old configuration file for backup.

cp ~/.xine/config ~/.kde4/share/apps/kaffeine/xine-config

Since this new xine configuration is in the new Kaffeine version 1 KDE4 location, it may only modify how the new Kaffeine works and nothing else running in KDE4, but it is still an interesting find.

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.

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):


... 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.)
