Re: GT430 On Linux (Slackware64 13.1) not recognized by ALSA
An updated bug report would be helpful since that includes various other audio information.
Does your distro use PulseAudio, some other audio daemon, or do applications talk to ALSA devices directly?
You shouldn't really need to use alsaconf to get HDMI audio working. Try:
1) Make sure you're running X using the NVIDIA driver and it's driving your HDMI monitor.
2) Run alsamixer -c 2 and unmute everything.
3) Run the following; one of them should work:
speaker-test -c 2 -r 48000 -D hw:2,3
speaker-test -c 2 -r 48000 -D hw:2,7
speaker-test -c 2 -r 48000 -D hw:2,8
speaker-test -c 2 -r 48000 -D hw:2,9
