Thank you for reporting this bug to Ubuntu. Ubuntu 9.10 (karmic) reached end-of-life on April 30, 2011.

[Bug 466957] Re: pulseaudio takes 100 % CPU when using 5.1 profile
As I never figured out how to solve this problem, I switched to my Realtek-Onboard-Sound for a while. A few days ago I tried to use the CA0106 (SB Live!) again with 5.1 channels and noticed, that no more 100% CPU occured. Instead pulseaudio randomly crashed and sound suddenly stopped on any application. /var/log/messages: stale PID file, overwriting, due to the auto-respawn-option I guess. I deactivated that and started pulseaudio manually -: E: alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write! E: alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_ca0106'. Please report this issue to the ALSA developers. E: alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value min_avail. D: protocol-native.c: Underrun on 'Audio Stream', 0 bytes in queue Even when I tried to fix the 100% CPU thing, there were some thoughts about it being a CA0106 driver problem, and not really a pulseaudio issue. So I decided to try the upstream-version of linux-alsa-driver- modules, following this guide: https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules That did the job. No more 100% CPU, no more sudden crashes, everything is working fine now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/466957 Title: pulseaudio takes 100 % CPU when using 5.1 profile -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

One year ago I switched to Arch Linux and pure alsa without pulseaudio and never noticed something like this bug.

I tried putting the line export PULSE_NO_SIMD=1 in /etc/profile which did not help. Before that I tried putting it in /usr/bin/start- pulseaudio-x11 which also did not change anything.

[Bug 466957] Re: pulseaudio takes 100 % CPU when using 5.1 profile
I was seeing this with Karmic (x86) and a CA0106 when trying to use more than 2 channels: 4, 5.0, 5.1, or the surround-sound system installed with this PC, 7.1, for home theatre. After upgrading to Lucid this same issue occurs. The only workable configuration is stereo. It is incredibly frustrating, especially as the custom 7.1 ALSA configuration that was used pre-Jaunty worked fine. -- pulseaudio takes 100 % CPU when using 5.1 profile https://bugs.launchpad.net/bugs/466957 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
