Default Re: GT430 On Linux (Slackware64 13.1) not recognized by ALSA

alsamixer will only show a mute control for HDMI audio cards; since the signal is digital, there's no other volume etc. controls that are possible. alsamixer should show OO for unmuted; MM is muted.

Your TV's information shows up in /proc/asound/card2/eld#3.0, hence the correct test command is:

speaker-test -c 2 -r 48000 -D hw:2,9

Perhaps you can try unplugging your webcam, and perhaps even disabling your built-in ATI sound-card in the BIOS, and rebooting. Perhaps there's some confusion within the ALSA driver. Note that the appropriate test command may change depending on the number of sound cards you have active; tyr also the following:

speaker-test -c 2 -r 48000 -D hw:1,9
speaker-test -c 2 -r 48000 -D hw:0,9
