alsamixer --> snd_ctl_open failed for default: No such device


Hello. I installed all the alsa business yesterday and got it all set, or so I thought. I ran alsamixer, unmuted everything, and I looked good to go. Since that time, I downloaded and installed MPlayer and XMMS.

Today I booted up and listened to a CD. When I closed out XMMS, a dialog box popped up with a message that said "alsamixer: snd_ctl_open failed for default: No such device."

I tried to run alsamixer, and it will no longer run. What did I do? How can I change things so I can run alsamixer and no longer see the error dialog box after using XMMS?

I'm not an experienced linux user by any means, so any help described in "plain" terms is greatly appreciated. Not to say that I've got anything against jargon, just that I don't pick up on it as quick.

Thanks.

I got this error by following the instructions in the first post here:

linuxquestions.org/questions/linux-newbie-8/alsamixer-function-sndctlopen-failed-for-default-no-such-file-or-directory-157454/

I started again from scratch, and in addition to alsa-driver, alsa-lib and alsa-utils I also installed alsa-firmware. Now it works fine.

Normally those ctl_open errors happen when the /dev/'s for alsa disappear (or never existed in the first place). If your user is in the audio group and udev is running you might try restarting udev, rebooting, or running the snddevices script in alsa-driver as a last resort.

# /etc/init.d/udev restart

Otherwise your alsa might not be fully installed. I've been getting some sort of /etc/modprobe.d/ stuff about must have a .conf extention, perhaps your distro implemented that and your configurations are no longer being looked at. Renaming and rebooting should fix it, at least temporarily, IF that's your particular problem.
