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.

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.

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 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!)

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?

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.)

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've setup an HTPC with xbmc, and I'd like to output the audio from the system to both my digital and analog outputs on my mother board. How do I do it? Can their be a script that duplicates the output of one to the other? Here's what aplay -l said:

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 trying to launch CoverGloobus (a fantastic little album art and current song display) and Rhythmbox simultaneously through a BASH script. Problem is that when I attempt to run the script the first time, CoverGloobus doesn't launch, but Rhythmbox does. Here's my script as it is right now:
Code:
#! /bin/bash
#Opens Rhythmbox and CoverGloobus
rhythmbox && covergloobus
done
I've double-checked the commands in gnome-terminal, and they're the right ones for launching the applications. Here's where it gets odd, though. The second time I run the script, CoverGloobus and Rhythmbox launch simultaneously. I've reproduced this scenario multiple times.

I work for a company that uses Ubuntu exclusively. Without going too much into detail, we need a single sound-card to do up to 3 things at one time. What I mean by this, basically, is that there needs to be 3 instances listening to a card's line-in port at any one time. For example (these are made-up), Audacity listening to the line-in jack and making a recording of what it hears, a custom script that streams the input to the internet, and a third instance that listens to this input and runs different scripts based on what it hears.
Currently, our company sends out machines with 3 sound cards to do this. One card for each job. Of course, we'd like to save money and only send out one. Whenever we try to set all 3 programs to run off of one card, they error out and say something along the lines of "device already in use". Is there a way to go around this? If so, how? We use the command-line version of Ubuntu 8.04. It is NOT x64. The hardware may vary a bit, but is for the most part, consistent. (We order in batches of 50.)

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 ?

Running 10.10 and win 7 on my HP dv6-2150us laptop and I'm having a few issues.
First how do I get HDMI audio output to my TV? I think I have just a integrated Intel graphics card. It works fine in windows but I can't seem to get it to work in Ubuntu. I tried searching but couldn't find anything pertaining to this issue.

This tutorial is meant for Ubuntu 9.10 Karmic Koala, but it might work in earlier or later versions as well. I wrote this tutorial mostly because it took me a full day of work using lots of help from people on #mpd and #pulseaudio from the FreeNode IRC server.The goal is to get the MPD daemon working using PulseAudio, but without it being dependent on the X server or a session. To do that we must configure PulseAudio to run in system-wide daemon mode (which is not recommended by the developers, but in this case we do not have a choice). This means it will be using the /etc/pulse/system.pa config file instead of the usual /etc/pulse/default.pa. We must also make sure the appropriate user/group permissions are set, or PulseAudio will be rejecting the connections.The result will be an interrupt-less music environment, not dependent on the X server. Meaning we can for example log out and log in without the music having to stop for even a second. Switching TTYs (Ctrl+Alt+Fx) will also keep the music playing (not possible by default). All that and PulseAudio will still be able to detect and configure all your devices automatically.
Instructions: Make sure you add your username to the following system groups: pulse, pulse-access and audio.Do that by going to System --> Administration --> Users and Groups.Click the unlock button (the one with a picture of some keys), then click Manage Groups. In the list of groups that pops up, for each of the previously mentioned groups click "Properties" and select all the users that you want to have this functionality.

I seem to be having a problem with my sound. Every time I start my computer, I hear the sound played at the login screen and the sound played when I login. Right then, every time, the sound cracks up and stops before it finishes. Running "ubuntu-bug audio" shows that ALSA works fine but pulseaudio does not. For reference, "pacmd list" says that there are 0 sinks, 0 sources and 0 caches.
Edit: Solved by a really stupid mistake: loose 3.5mm audio cable. Don't do that. your sound and you're on a desktop computer, go, right now, and check to make sure that you haven't made the same mistake as me.

I have an ATI Radeon 5850 card with 2 17" monitors, plus a 46" TV via HDMI (disabled, except for BD plaback under windows) under Debian 6.0/Squeeze. When I first installed this system, it worked fine with all 3 screens (only 2 enabled at a time). Sometime in the past few weeks though, it's decided to revert to a single-display setup. I can't find any errors in the logfiles, and it works perfectly fine when I re-enabled the secondary display via the ATI Catalyst Control center.
The auto-generated xorg.conf isn't configured to use the second display (even after re-generating one using "aticonfig -initial=dual-head"), and it is not being modified when I change settings in the Catalyst Control Center.Updating display settings after every boot is just a bit annoying.

Using the Pulse Audio manager does anyone know if it is possible to specify a particular sink or source to be used by a named program? I am assuming it will not be the same as the default.

I'm on 9.10 and I use huludesktop often to watch my Hulu queue. Every once in a while (and more so lately) the video freeze and the sound stutters. I then find that pulseaudio is taking 100% of a CPU (I have a quad core AMD 64bit machine). Killing pulseaudio causes huludesktop to continue without sound and a new pulseaudio starts up. I have to kill huludesktop and resume playback and then everything's OK, until it happens again.

I installed "Theocracy" on my 9.10 Karmic system. The installer asks for a sound device, dev/dsp is the default and I didn't change it. When I now try to start the game, I get the following error:
Unable to open sound device: Device or resource busy

What is the sound device when using PulseAudio on Karmic?

Why do this? Two reasons:
1) Many of us use JACK for low-latency audio work, but it's annoying to have to turn it on or off to have to allow regular Ubuntu applications to work. It's even more annoying that both can't normally work together -- either JACK or PulseAudio must take control of the sound control. This method allow JACK to do, and PulseAudio just routes to JACK.
2) JACK is kinda super awesome. By routing PulseAudio through it, your regular Ubuntu sound application suddenly get super powers. Pretty easy to do! (Well, we count our blessings in Linux...)
1. DYNAMICALLY You need the PulseAudio utilities and JACK sink:
Code:
sudo aptitude install pulseaudio-utils pulseaudio-module-jack And then run this to get PulseAudio connected to JACK: Code:pactl load-module module-jack-sink pactl load-module module-jack-source Now, go to Ubuntu's sound preferences, and you'll see "Jack sink" in the output tab. If you use JACK Control, you can create a script for the above and have it set up in "Execute script after Startup". Then, PulseAudio will automatically load the JACK sink when you start JACK.
2. BY DEFAULT Edit /etc/pulse/default.pa, and add these lines:
Code:load-module module-jack-source load-module module-jack-sink You can test it without rebooting by restarting PulseAudio. In Ubuntu, PulseAudio is started in the user session, not as a system daemon. To restart it:
Code:
pulseaudio --kill
pulseaudio --start

So there's just one DVD (Narnia) that won't play on my Ubuntu machine using Totem: other DVDs play (I've installed libdvdread4 and libdvdcss2 like a good boy) and non-pulseaudio players like VLC play it properly. If I completely remove and kill pulseaudio, it plays in totem fine. It gets to the language selection screen and I select English, but as soon as any sound is involved it doesn't play. Clicking Go --> DVD menu causes Totem to hang. I don't want to be uninstalling pulseaudio, and VLC player is a bit complex for the mother.
The output of totem:
Code:
marcus@margit-laptop:~$ totem
libdvdread: Using libdvdcss version 1.2.10 for DVD access
libdvdnav: Using dvdnav version 4.1.3
libdvdread: Using libdvdcss version 1.2.10 for DVD access
libdvdnav: DVD Title:
libdvdnav: DVD Serial Number: 43D1F9FE (GEAR):
libdvdnav: DVD Title (Alternative):
libdvdnav: Unable to find map file '/home/marcus/.dvdnav/.map' .....
marcus@margit-laptop:~$
Note that before the last line, Totem does absolutely nothing. It just sits their. Like it's trying to devour my soul or something.
