ALSA Errors During Shutdown
Last modified: 2007-11-30 17:11:48 EST
Description of problem:
During a system shutdown the alsa system reports an error and after a reboot the
volume is set to muted. The error reported is as follows:
get_control:149: Cannot read control info '2,0,0,Capture Volume,0': Invalid
Also, when trying to start the amixer utility, the following error is reported:
amixer: Mixer default load error: Invalid argument
Version-Release number of selected component (if applicable):
System: Dell XPS 700
CPU: Intel Core 2 Duo
Steps to Reproduce:
1. Errors are reported during every shudown.
2. Invoked amixer from the command line.
One thing I failed to mention. When the system boots, the sound system works.
I get the system sounds, play music, etc. The volume is always reset to muted
and the errors are reported during shutdown.
Sorry for the extra posts, maybe I will get all of the information needed here.
The sound card detected was as follows:
Vendor: nVidia Corportation
Model: MCP55 High Definition Audio
I believe this is detection is proper. It is integrated with my motherboard. I
do have a second sound card installed, a Creative Labs Sound Blaster X-Fi;
however, I have not selected it as my primary sound card since there are
currently no drivers for this card (as I understand it).
Right, Sound Blaster X-Fi isn't supported yet.
Could you please attach /root/scsconfig.log?

I have attached the scsconfig log as requested. I have also attahced the
scsrun.log as it shows the error that I am receiving from amixer if I try to run
it: "amixer: Mixer default load error: Invalid argument".
Thanks for you quick response. Let me know if you need anything else.
I have the same error message on system shutdown.
This is on a Dell Dimension E520 with an integrated
Intel soundchip: 82801H (ICH8 Family) HD Audio Controller
using the 'snd-hda-intel' driver.
I see this with both the kernels:
current development kernel fixes my issue with snd-hda-intel.
alsactl, amixer and alsamixer now work for me without issue.
System is a Dell E521 Desktop currently running 32bit fedora.
with lspci reporting
Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2)
This is a real problem with the 1.0.12 upstream alsa drivers. I believe this is
fixed with the 1.0.13 drivers according the the alsa driver Changelogs I have
read. Who do I have to bribe to get newer upstream alsa drivers into the next
fedora core 6 update kernel?
I think Dave Jones makes updates for FC kernels. AFAIK he uses the latest
upstream kernels for it so the 1.0.13 drivers (or later) will be in FC-5/6 someday.
It appears the latest ALSA, or kernel updates fixes the issue. I no longer see
this error during shutdown. Thanks guys for the support. :)
