Red Hat Bugzilla – Bug 425871
pulse audio occasionally fails to initialize after a reboot.
Last modified: 2008-01-01 00:47:06 EST
Description of problem: Under certain reboot situations, pulse audio does not start. It takes a poweroff reboot to get it to function properly. Version-Release number of selected component (if applicable): How reproducible: It is random. I am curious about other distributions and also, my defaults, which are F8-64bit (on one drive) and F7-32bit on the other. If I "evaluate" the other distributions, and I then return to F8_64bit there is no assurance that pulse audio will start. Note. This problem is random. Steps to Reproduce: 1. 2. 3. Actual results: No audio whatsoever. Expected results: Pulse audio should always restart. Additional info: The mother board is an intel d945gnt, the system memory is 3gigs. The bios is dated Sept 2007. F8 is current as of filing this bug report.
Are there relevant error messages or log files generated when it fails? Check in /var/log/messages and dmesg for anything unusual at the very least. There's very little information for anyone to take any action on here.
Created attachment 289746 [details] cat messages | grep pulse > /tmp/pulse.log Hope this helps Jon.

This seems to me as a kernel/alsa or BIOS problem. Is there a BIOS update for the board available? Please compare outputs of "amixer -c0 scontrols" in cases when sound works and when not. Thanks!
Re bios update. My mother board is an Intel D945gnt with the most recent bios, as I indicated in the initial entry. Today is Dec 26th, and the problem has stopped occurring. Since raising this bug(let) ndiswrapper and some other related updates have occurred and I have not experienced this problem for at least 10 days. I would drop the priority of this problem to zero, and I will check back in January. If it works ok for 3 weeks, I will close this bug report. Since the bug is a small one, I call it a buglet.
Today is January 1, 2008. Since Dec 26, with around 5 boots per day (I have an experimental Fedora 8 system), pulse audio has started every time. I believe that patches in the system since the Nov 2007 release have repaired the problem.
