General :: Pulseaudio Selectively Detect Sound Hardware?
Nov 2, 2010
I am running Ubuntu Netbook Remix 10.04. I have been having some problems recently with Pulseaudio, which has traditionally worked fine for me on this netbook actually. Specifically, when I boot the computer, the system will play the "Bongo roll" sound at the GNOME login screen, telling me that sound hardware has been detected and should be working fine.
Yet when I log into the Netbook interface, my volume notification icon has the three blank lines indicating my session does not have access to the sound hardware. Nor do any of the built-in Sound preference panels detect my hardware, only registering dummy output. Finally, the (hopefully) deprecated PulseAudio Device Manager and Volume Control applications also fail to detect my hardware.
However, this problem is inconsistent! It will only happen on certain boots, though the number seems to be hovering around 75% of boots where pulseaduio fails to load correctly. The daemon/service is running, and restarting it only returns:
jmmcl2@unteer:~$ sudo service pulseaudio restart PulseAudio configured for per-user sessions ask again, why is my Pulseaudio being so selective about detecting my sound hardware in Ubuntu 10.04?

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 ?

I installed a sound card but when I go to System->Preferences->Sound and go to Hardware it's not showing anything at all. If I boot from the Live CD then it will show the card and it works. How can I make my Linux installation detect this card? I was thinking that I could somehow copy the necessary files from the Live CD to make this work, but maybe there's an easier way.

need all spaces between two letters or a letter and a number exchanged for an underscore, but all spaces between a letter and other characters need to remain. One example for clarity:
Input:
force -- lamin 90 [label]
active A -- generation [label]
needed Output:
force -- lamin_90 [label]
active_A -- generation [label]
I tried solving this with sed but obviously s/ /_/g does not work, nor does any s/[a-zA-z0-9] [a-zA-z0-9]/[a-zA-z0-9]_[a-zA-z0-9]/g , because you just can't do this...

I just removed Pulseaudio from both Fedora and Kubuntu due to the way it stalls other programs from launching after logging into KDE. After rebooting Kubuntu, KDE sounds, JuK and VLC all had sound, presumably via ALSA.
However, Fedora has KDE sounds but no sound in JuK or VLC. When I launch JuK, KDE reports that the HDA Intel analogue device does not work. Could this relate to Gstreamer? If Fedora falls back to ALSA if Pulseaudio is removed, does Gstreamer require additional plugins? Kubuntu has "gstreamer0.10-alsa", but Fedora doesn't seem to have an equivalent.

I cannot get sound to work with my new installed Opensuse 11.2. If I check yast (sound card configuration), I can play a nice testsound. However, Kde (I am using kde 4.4.2) does not issue any sound at all.

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 did a system update a few days ago and now my sound won't work. The only packages that might of affected sound that were updated (that I noticed) were a few kernel updates and pulseaudio. Is there a way to downgrade pulseaudio? Or do I have to do something else?

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'm using Fedora 13 and think this behavior comes from Pulseaudio. To make it simple, all my sounds are played in my GNOME session. What's making sense because it's where Pulseaudio is launched. So, when I switch VT (CTRL+ALT+Fx), all sounds from my GNOME session is muted. What's not the actual problem. It's in fact a good behavior. The problem is I use some VirtualBox virtual machines on other VT launched with the xinit command.
These VMs emit sounds but I'm not able to hear them because I'm not on the VT of my GNOME session. But once I get back on my GNOME session I can hear all sound from the VMs. What I want, it's to be able to hear all sounds played by the VT on which I currently am and not everything and only in my GNOME session. How I can accomplish that?

I've run into a couple of issues that appear to be related to PulseAudio. First, since I upgraded to FC13 a couple of weeks ago, I get no sound from flash on websites. Yesterday, I had a need to record some audio into my computer via the mic input. So, I installed Audacity, but it couldn't see the signal coming in, even though it was playing from the sound source. I did a bit of digging and found a note on the PulseAudio website that said that Audacity didn't work with PulseAudio. So, I removed PulseAudio, rebooted for good measure, and under ALSA, Audacity was able to record from the mic input.
When I was finished recording, I started Amarok playing, and I could see the progress indicator moving across the interface, but there was no sound. I checked the mixer, but nothing was muted, and the audio from Audacity was working just fine. So, I reinstalled PulseAudio. Today, I needed to do more recording, so I pulled off PulseAudio once more. I did my recording, and then tried Amarok once more without PulseAudio, with the same results. It occurred to me that I should try a website with flash and see if those work without PA installed. Indeed they do.
So here's what I have: Audacity can't record from the mic input with PA installed.
Amarok doesn't produce sound without PA installed
Flash websites don't make sound with PA installed
This all worked while I was using FC12 (though I never tried Audacity), and I've only had problems since I upgraded to FC13.

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
Aborted
Execution of /usr/games/theocracy_base/theocracy.real failed!
What is the sound device when using PulseAudio on Karmic?

Yesterday I decided to remove pulse (mainly because Skype was unable to work with it) but suddenly the sound icon is gone. After some searching on the net I understood that it was part of pulseaudio, but now I feel a bit lost. Alsa works like a charm instead, but since I also want to use ubuntu to record sound I'm not sure if it will work, and also I have a sound source for my HDMI interface and don't know how switch if I want to.

Just like the title says, when I use mpd with pulseaudio, I get no sound but clients appear to be playing (ncmpcpp and gmpc). Other players such as vlc or mplayer work just fine. If I go under the mixer, I get "no application is currently playing or recording audio" under the "Applications" tab when playing through mpd. In contrast, when I'm using mplayer or vlc, both show up in that tab. It behaves as though pulse is simply not configured to work with mpd.Here is my config (edited out any commented line for brevity):
Code:
$ cat /etc/mpd.conf | sed '/#/d'
music_directory"/media/data/DM/Genre"
playlist_directory"/var/lib/mpd/playlists"
db_file"/var/lib/mpd/mpd.db"
[code]....

Pulseaudio setup. My pulseaudio was working when I was using FC11 and it stops working after I upgrade to FC12 using preupgrade. The system sees audio device and alsa is working correctly. No audio at all (system audio and mplayer) from Pulseaudio. I am using the onboard Intel audio. The verify from the alsamixer that the volume is not muted. I also tries all the combination of profiles in the pavucontrol and in some of the profiles, I can see the output volume bar is moving, but still no sound
pulseaudio-0.9.19-2.fc12.x86_64
alsa-plugins-pulseaudio-1.0.21-2.fc12.x86_64
Attached is the pulseaudio log when playing video from mplayer.

I took out some USB speakers that had been working for many months because I needed them on another PC. I plugged the audio out (lime colored female connector on back of Ubuntu PC) into my stereo receiver's VCR audio in (Red and white jacks), no sound. Yes, the cable is fine (same cable I took off the other PC which was working fine), and the receiver is set to VCR. I recall having to go through some hoops to get the USB speakers working way back when. The Pulseaudio volume control shows left and right pulsating bars when I have on Pandora, but sound is obviously not being sent to the right output. I also tried the optical audio out on the PC into the receiver's DSB optical in but again no sound.

Any sound playing through pulseaudio is distorted for the first half-second or so. Sounds like a buzzing or crackling or something. This happens, for example, in Pidgin and Clementine (music player). If I set these programs to output through alsa instead of pulseaudio, there's no such problem. Also no such problem existed in 10.04. And I tried the fix in the sticky, nothing changed. Probably less than a half second of distortion, really. Maybe 100ms.

I tried to change to 5.1 from stereo and lost sound entirely. To get sound back I had to uninstall pulseaudio, but that gives me sound only on my right front speaker and sub.Whenever I install pulseaudio again I lose sound all over again.

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've been trying to use Wine to make Foobar work in Linux. The program does work, but it doesn't make a sound. For the rest, is works perfectly. I'm having the same problem with any Flash application I try to run: everything works, but without a sound. Amarok, however, doesn't have this problem.Somewhere I found that such problem might be related to Pulseaudio. So I tried going on the Pulseaudio configuration under "other" in the sound panel in YaST, but it tells me that Pulseaudio is not installed or cannot be configurated. I tried installing the package via Terminal, but it tells me that patterns-openSUSE-kde4_pure-11.3-22.1.x86_64 conflicts with pulseaudio given by pulseaudio-0.9.21-10.1.1.x86_64. I would have to delete it, if I wanted to install pulseaudio.Now I don't know where to put my hands. I am not good at this I'm not even sure I would solve my trouble installing pulseaudio, anyway. I'm using a sony vaio VPCEA3C4E with openSUSE 11.3 KDE installed trough USB key.

I had sound in Jaunty, and I just upgraded to Karmic, and everything else is working 100% ok. Except for sound. I have no sound at all if I use any other driver than OSS. I have pulseaudio installed but it doesn't recognize my sound card.
Here's the output from pulseaudio -vvvv:

I installed the pulseaudio equalizer today on my Karmic desktop using the instructions at URL...When I enable the equalizer via the GUI checkbox, my sound instantly becomes garbled. When I disable it the problem disappears, but then I can't use the equalizer, which was the point of the exercise. I found some suggestions about editing /etc/pulse/default.pa, but the parameters concerning module-hal-* don't appear in my default.pa. I also have read through a couple of Audio Troubleshooting guides without finding this particular symptom.

I have Ubuntu 9.10. I was having trouble with sound in Skype. So I read on the forum that I needed to replace pulseaudio with esound, more or less as described here:
[URL]
I did that and skype is working!
But now there's no more sound control on the panel. It doesn't offer a sound control when I right click and look through "add to menu". I saw a post that said that the sound control would appear in the "indicator applet" on the the panel, but that didn't work.
Preferences--sound gives me a message "waiting for sound system to respond." The solutions that I've read on forums seem to imply that I need to reinstall pulseaudio. But that will bring me back to my original problem with Skype.Do I need to upgrade to the new version of Ubuntu to fix it? I hadn't upgraded because I've been told the newer version is a bit slower.

Here is the update to the old thread that somehow disappeared "HOWTO: A52 Encoded 5.1 Surround Sound Awesomeness with PulseAudio and ALSA on Hardy" thread (archived here). See also this bug report.There are two steps here: add the a52 plugin, and tell pulseaudio to use it.
Step 1:
Go to a terminal and do the following:
Code:
sudo bash
echo "pcm.a52 {[code]....
Pulse should come back on its own unless you disabled autospawn.Now pulse should be aware of your digital surround output. Go to System -> Preferences -> Sound. Click on the "Hardware" tab and change the profile to one of the 'Digital Surround 5.1' profiles. Play some sound (I like to test with www.pandora.com) and enjoy!If it doesn't show up, it probably means that alsa didn't create it correctly. To test if alsa sees the a52 device, type:
Code:
aplay -D a52:0
If it errors out (audio open error: No such file or directory) then that means it did not like your asound.conf settings. You might learn something by looking at the output of 'sudo alsa reload' or just 'aplay'.[code].....
