Red Hat Bugzilla – Bug 194009
Sounds fails on boot intermittently
Last modified: 2007-11-30 17:11:34 EST
Description of problem: I'm running FC5; it's fully up to date off the updates/extras/livna repos. When I have to reboot the machine, sound fails about half of the time. When the sound fails to work, I simply reboot again and that often, but not always, fixes the problem. I'm doing nothing to the machine at all from the time the sound fails to the time it works, aside from clicking System | Shut Down and then Reboot. I'm assuming this is an alsa issue, but really not sure. This problem has been present for me for several versions of Alsa in FC5, but never once in FC4. Version-Release number of selected component (if applicable): sudo rpm -qa | grep alsa produces: alsa-lib-1.0.11-4.rc2 alsa-utils-1.0.11-4.rc2 alsa-lib-debuginfo-1.0.11-4.rc2 alsa-lib-devel-1.0.11-4.rc2 /sbin/modprobe --list | grep alsa produces: /lib/modules/2.6.16-1.2122_FC5/kernel/drivers/media/video/saa7134/saa7134-alsa.ko /lib/modules/2.6.16-1.2122_FC5/kernel/drivers/media/video/cx88/cx88-alsa.ko How reproducible: An a machine with the CX88 driver, I'm assuming this problem should be reproduced. I can't tell why it happens in the first place, since sound sometimes works after boot, and sometimes doesn't. Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: Please let me know what other info I can provide... thanks!
Please attach output of "amixer" utility when sound works and when it doesn't (just after boot).
Since upgrading to the 2.6.17 kernel, I've been unable to duplicate this problem. Several reboots, both using kernel 2139 and 2145, have been normal with sound working properly. I've been keeping all packages up to date, so this may be coincidence... but this problem has not happened again since moving to the 2.6.17 kernel.
