No Audio over Nvidia Geforce 210 HDMI

I cant seem to figure out how to get sound over HDMI on my NVIDIA Geforce 210. As a starting point, it works in windows 7, so I'm pretty sure ts not the card. I tried to install the NVIDIA proprietary drivers, but the install script kept failing. I read a bunch of posts, mostly ubuntu based, played around, and did more damage than good. I eventually just did a fresh install and update, and am going to try again. Since I consider myself a beginner, working on intermediate, linux user, some of the command line output is a bit foreign. I'm pretty sure the sound is recognized, but not configured properly. If someone could point me in the right direction to start, I think the feedback could become more constructive.

Thanks.

this worked for me on an Asrock 3D-ion.

first, in terminal, type alsamixer and unmute everything
or, if you don't want to use teminal, install gnome alsa mixer through synaptic

Then, edit the file /etc/asound.conf In my case, I had to create the file.

Code: Select all

sudo gedit /etc/asound.conf
and enter the following

Code: Select all

pcm.dmixer {
  type dmix
  ipc_key 2048
  slave {
    pcm "hw:1,7" # Always use pure hw. dmix will reformat/resample audio.
    period_size 512 # If you get stuttering/or non-working audio, fiddle around with these
    buffer_size 4096
    rate 48000 # HDMI, I'll assume 48kHz
    format S16_LE # Should be default for pretty much any soundcard.
  }
  bindings {
    0 0
    1 1
  }
}

pcm.!default {
  type plug
  slave.pcm dmixer
}
and reboot
