Red Hat Bugzilla – Bug 259061
kernel-18.104.22.168-42.fc6 upgrade killed sound on VIA VT1720/24
Last modified: 2008-02-07 23:24:16 EST
Description of problem:
There is no sound after upgrading to kernel-22.214.171.124-42.fc6.
Audio applications act normally (there are no errors), but there is no audio output.
Worked OK with kernel-2.6.20-1.2962.fc6
See the attached scsconfig.log
Created attachment 174941 [details]
After rebooting back into the 2.6.20 kernel, there still was no sound output.
I powered off, then flipped the master power switch at the back of my machine off.
I flipped this switch on again, hit power, then booted into the 2.6.20 kernel.
Now the sound is working again.
I have had to use this total poweroff routine in the past. Even on a pre-2.6.22
kernel sound would fail to work once every few months. I suspect the audio
hardware is not being properly initialized by the driver.
(This is a mass-update to all current FC6 kernel bugs in NEW state)
I'm reviewing this bug list as part of the kernel bug triage project, an attempt
to isolate current bugs in the Fedora kernel.

Please attempt to reproduce this bug with a current version of Fedora (presently
Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a

Thanks for using Fedora!
