This looks like a bug in alsa lib. You can get the latest alsa lib hg snapshot at ftp://ftp.suse.com/pub/projects/alsa/snapshot/, compile it, and install it. The bug might be gone as things move very fast in alsa. If it isn't, it would be good to post this problem on alsa-devel. You can edit /etc/asound.state directly. This file resides in /etc or /etc/alsa/ depending on your distro. Here is a representative entry from mine. control.18 { comment.access 'read write' comment.type INTEGER comment.count 2 comment.range '0 - 127' iface MIXER name 'PCM Playback Volume' value.0 103 value.1 103 } What you want is to look for the same name (if you are using PCM), and then set the value.0 and value.1 to be something greater than 0. Try half at first (of the range) so you won't blow anything out if it is very sensitive. This at least gets you sound, though it isn't as convenient as using the mixer. You will have to be root to edit this and if you aren't familiar with unix editors (vim or emacs) you should probably use something like pico. Or Knotes or Text Editor in the gui.
