Thanks again for the help Takashi. Ok, I've created the /etc/asound.conf file with the appropriate group and now I'm trying to run the aplay binary and I'm not getting any error messages, but I'm also not hearing any sounds from the speakers.

I've made sure nothing is muted with the audio hardware by using alsamixer and changed the permissions on the files within the /etc/snd directory. Any other thoughts?

bump for help
You didn't give any useful information about the hardware itself, so no one can answer. Did it ever sound correctly with any other distro at all?
Please don't mix up the custom-build problem and the driver problem. The problem with silent output is more likely a driver issue (or a configuration issue).
Takashi
The hardware is an integrated HDA Intel audio sound card. The /proc/asound/pcm file has this listed:
00-00: STAC92xx Analog : STAC92xx Analog : playback 1 : capture 2 00-01: STAC92xx Digital : STAC92xx Digital : playback 1 00-03: INTEL HDMI 0 : INTEL HDMI 0 : playback 1
That's not enough. Which kernel / ALSA version, which model option? Could you alsa-info.sh output (run with --no-upload option)? This will give most of needed information.
Yes, this audio works just fine within Kubuntu.
Do both run the same kernel version?
At next, try to run "alsactl -f somefile store" on both systems, and compare the files. You may see some difference in mixer setup.
Takashi
I've searched the local fs for the alsa-info.sh script as well as looking through the package contents on debian.org without any results.
See Documentation/sound/alsa/HD-Audio.txt.
