Everybody, first look through this list: https://wiki.ubuntu.com/DebuggingSoundProblems/KarmicCaveats and if you're still having problems (and you're not the original bug reporter), please file separate bugs with this terminal command ubuntu-bug -p alsa-base Also, if you have the possibility to check whether the problem still exists in current Lucid, that will be most helpful.

This bug has been addressed at: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/424655 The bug is not resolved, but are two possible workarounds (choose the one you're most comfortable with). 1) replace udev 147~-6.1 with: udev 147~-6 (force version in synaptic) (NOTE: there is a known issue regarding auto mounting USB devices that is fixed in the later version. If this is a concern - see below) 2) rebuild udev 147~-6, apply patch to fix external USB device issue rebuild and deploy (follow instructions by Martin Pit starting: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/424655/comments/54) pulseaudio now sits at 6.4 MB resident and 260MB virtual - ah... machine performance is restored! PS I found stopping rhythmbox, reinstalling pulseaudio, then killing pulseaudio sufficient (rather than rebooting). Pulseaudio is set to autostart by default. -- [karmic] ALSA driver snd_hda_intel broken according to PulseAudio https://bugs.launchpad.net/bugs/430620 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
[Bug 430620] Re: [karmic] ALSA driver snd_hda_intel broken according to PulseAudio
I have the same weird behaviour from the sound system. HP Mini 2133, fresh Karmic installation. uname reports 2.6.31-14-generic. pulse says card not found - dummy audio. After several trials I can say the problem most likely stands in the (configuration of) snd-hda-intel module. In fact, the original installation left me with no sound; after some googling I commented out in /etc/alsa-base.conf: options snd-hda-intel power_save=10 power_save_controller=N Still no sound. Then I added: options snd-hda-intel enable_msi=1 This partially worked. Now if I open Rhythmbox and start playing a long sequence of songs, no sound comes up, at the beginning. Then I do al alsa force-reload and the sound appears, even if still are WARNINGs complaining about fuse .gvfs-fuse-daemon file system BUT THE SOUND IS NOT PERMANENT: randomly it disappears, maybe after 5 seconds or after 20 minutes; every time it disappears I just do an alsa force-reload, always with rhythmbox playing, and it reappears for another (random) period of time. Obviously the CPU load goes to 100% in sync when the sound is played, pulseaudio and pavucontrol accounting for a cumulative 50% of the load itself. Intersting to note, on another HP machine (Compaq 6710b) upgraded from 9.04 this issue is unknown... Hope it helps the ALSA guys. I'll keep in touch with this bug trail.

Note that the first error occurs 8 second before the rest (last 3 lines) so it may be unrelated. Ignoring the logs and moving to actual user experience with sound: * Ever since the switch to pulseaudio I get occasional random/spontaneous sound stutter, even when no sound is playing * Since the karmic upgrade the stutter events are much shorter in duration and much rarer in occurrence, so I'm speculating (and may be totally wrong) that the logs are evidence of better exception handling. Better get some log messages than actual sound stutter.

[Bug 430620] Re: [karmic] ALSA driver snd_hda_intel broken according to PulseAudio
I've noticed a problem with pulseaudio too - every so often my machine (msigx620 with 4MB RAM) starts running really slow. System Monitor showed (today) 1.8GB of virtual memory used by pulseaudio - without producing any sound. Uptime 5:35. Otherwise Karmic is running pretty well. uname -a 2.6.31-15-generic #50-Ubuntu SMP Tue Nov 10 14:53:52 UTC 2009 x86_64 GNU/Linux Machine is nice and responsive now (once pulseaudio was killed). Monitoring pulseaudio in System Monitor shows 2.8 MB of Virtual Memory being consumed per minute - so 1.8GB would take roughly 10 hours - so perhaps the rate varies.

I appear to have the same here on an upgrade to Ubuntu Karmic 32bit. It tends to happen more often with multiple audio sources playing simultaneously, and particularly with high bitrate FLAC audio. The app (Rhythmbox/Listen) will typically run with 100pc CPU utilisation thereafter, albeit successfully. Sound card is a PCI Creative X-Fi XtremeAudio running under CA0106.
