View Full Version : [ubuntu] pulseaudio causes mozilla, thunderbird to freeze.

I've upgraded from Jaunty to Karmic earlier this week, and having a nasty time with it.

Pulseaudio seems to be a big source of my problems. I've noticed that when Thunderbird attempts to play a new mail sound at the same time mozilla is playing a flash video, one or the other or both will hang. If I run "pkill pulse", all is well again.

I *think* the error I'm getting in user.log is:

Nov 5 08:58:28 pergamon pulseaudio[2569]: alsa-sink.c: Error opening PCM device front:0: Device or resource busy

.. but I haven't explicitly checked it yet.

I've also had mythbuntu issues directly related to pulseaudio that were solved by uninstalling pulseaudio. However I'm worried about removing the ubuntu-desktop package and what that might do to my backend Karmic ubuntu server.

Pulseaudio has been the source of about 50% of my headaches for the household karmic upgrade.

Are there any hints for diagnosing a pulseaudio freeze? I'd rather try to solve this than simply delete pulseaudio and have a slightly broken system.

edit: mine was a clean install with clean firefox profile and the 64bit alpha flash

Well, I'm giving up... removing pulseaudio on my server. It may screw up future updates but not having to open up a terminal and type "pkill pulse" twice a day will give me a bit of peace.

EDIT: Well, if I attempt to play two audio sources at once, one is muted. Better than having one or both applications hang.

I also had quite a lot of trouble using pulseaudio, especially when I was recording sound. I also had stuttering playback of sound, which I fixed by just removing pulseaudio and instelling esound, and rebooting:

sudo apt-get purge pulseaudio
sudo apt-get install esound
However, this seemed to kill all my recording capabilities, but playback sounded quite ok. Now I just use an usb sound system I had laying around and that seems to work fine in pulseaudio.

BTW: removing pulseaudio didn't remove ubuntu-desktop for me, so it could easily turn it around when it didn't work
