Mixer settings go wrong after upgrade from fc6
Last modified: 2007-11-30 17:12:05 EST
Description of problem:
After an upgrade from fc6 my mixer settings went mad: there were way too many
switches, and sound was much too low
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install fc6
2. Upgrade to fc7
Mixer settings are all wrong and sound is too low
Everything works fine as before
I have a Realtek ALC861 chip on an Toshiba Satellite A100-847 laptop. I managed
to work around the problem by putting:
options snd-hda-intel model=auto
into /etc/modprobe.d/alsa-base. Mixer settings now work as they used to in fc6.
Moreover, I installed an f7 kernel under fc6 a few times while debugging
suspend, and results were similar.
Still present in 2.6.21-1.3228.fc7. I deleted the workaround and mixer went
Thanks for filing this bug which I'm reviewing this bug as part of the kernel
bug triage project, an attempt to isolate current bugs in the fedora kernel.
I am CC'ing myself to this bug and will try and assist you in resolving it if I can.
There hasn't been much activity on this bug for a while. Could you tell me if
you are still having problems with the latest kernel?
If the problem has gone away then please close this bug or I'll do so in a few
days if there is no additional information lodged.
Thanks for reminding me to retest this one. Situation is similar to my suspend
problems: kernel-188.8.131.52-76.fc7.x86_64 is busted and needs the workaround,
while the rawhide kernel-2.6.23-0.174.rc6.fc8.x86_64 seems to work well without
it. I'll close the bug for now and reopen it should the f7 2.6.23 fail.
