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 argument 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): Kernel: 2.6.18-1.2798.fc6 System: Dell XPS 700 CPU: Intel Core 2 Duo ALSA: 1.0.12-2.fc6 How reproducible: Very. Steps to Reproduce: 1. Errors are reported during every shudown. 2. Invoked amixer from the command line. 3. Actual results: Expected results: Additional info:
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 Module: snd-hda-intel 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: kernel-2.6.18-1.2849.fc6 kernel-2.6.18-1.2798.fc6
FYI 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? -jef
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. :)
okay, closing.
