https://bugzilla.novell.com/show_bug.cgi?id=468436 Summary: sound card disappears periodically under 11.1 - no problems w/11.0 or 10.3 Classification: openSUSE Product: openSUSE 11.1 Version: Final Platform: x86-64 OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Sound AssignedTo: tiwai@novell.com ReportedBy: jnelson-suse@jamponi.net QAContact: qa@suse.de Found By: --- User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.5) Gecko/2008121300 SUSE/3.0.5-1.1 Firefox/3.0.5 I have a T61p Thinkpad which ran great under 10.3 and 11.0, but under 11.1 I've had no end of sound issues. The first thing after trying and failing several times to get pulseaudio to work, I gave up and removed everything pulseaudio that I could and made sure it was disabled in /etc/sysconfig and went back to using alsa. More or less things work OK except the sound system is very unstable - applications will either hang trying to access the sound device or, what happened today, in the middle of playback the sound device "disappeared". aplay now reports there are 0 sound cards installed The first symptom is that playback stops and the device is reported as busy, then subsequent attempts fail with permission denied, and then nothing works at all: The only messages I've found are in ~/.xsession-errors - there is NOTHING in /var/log/messages or dmesg output.

Sometimes it takes more than a day and sometimes it's immediate. I know that twinkle (VOIP phone) was pretty stable under 11.0 and is so far very unstable under 11.1, and using strace it appears to be sound issues.
