Okay,
I found this online, and I know it says to tweak it, but i'm not sure how to
do that. i can watch HDTV no problem using my hd3000 card, but the sound is
nothing but static. Now I can hear music and tv fine over the analog
output, but no sound via spdif output both are from onboard audio. This
first part is what I get when i run aplay -l. I've read of other people
having the same problem...but i can't seem to fix mine.

# ~/.asoundrc or /etc/asound.conf
# ALSA configuration file
##### USAGE #####
# Save this file as "~/.asoundrc" (for user-specific sound configuration) or
# "/etc/asound.conf" (for system-wide sound configuration) and specify ALSA
# device names ad described in the next section.
##### DEVICE NAMES #####
# This configuration file defines four devices for use by the user. Those
# devices are "analog", "mixed-analog", "digital", and "mixed-digital". The
# user may also re-define "default" to be identical to one of the
above-named
# devices ( i.e. to send all sound output to the digital output unless
otherwise
# specified). Use the device names as described below:
# - "analog" outputs to the analog output directly and (at least on
software
# sound cards) blocks other audio output. After playback completes,
"queued"
# sounds are output in sequence.
# - "mixed-analog" mixes audio output from multiple programs into the
analog
# output (so you can hear beeps, alerts, and other noises while playing
back
# an audio stream).
# - "digital" outputs to the digital output directly. Since most (all?)
# digital outputs expect 48kHz PCM audio, this may not work for some
playback
# (i.e. CD's--which are 44.1kHz PCM audio--or 32kHz audio streams from TV
# recordings, etc.).
# - "mixed-digital"
# All other devices created within this file are used only by the
configuration
# file itself and should /not/ be used directly. In other words, do not use
# the devices "analog-hw", "dmix-analog", "digital-hw", or "dmix-digital".
##### IMPORTANT #####
# To make this ALSA configuration file work with your sound card, you will
need
# to define the appropriate card and device information for the "analog-hw"
and
# "digital-hw" devices below. You can find the card and device information
# using "aplay -l".
##### Configuration File #####
# Override the default output used by ALSA. If you do not override the
# default, your default device is identical to the (unmixed) "analog" device
# shown below. If you prefer mixed and/or digital output, uncomment the
# appropriate four lines below (only one slave.pcm line).
#
# Note, also, that as of ALSA 1.0.9, "software" sound cards have been
modified
# such that their default "default" device is identical to the
"mixed-analog"
# device. Whether using an ALSA version before or after 1.0.9, it does no
harm
# and has no affect on performance to redefine the device (even if the
# redefinition does not change anything). Also, by using this ALSA
# configuration file, you once again have access to unmixed analog output
using
# the "analog" device.

# - Therefore, we can specify "hw:0,0", "default", or "analog" to access
analog
# output on the card
# - Note that as of ALSA 1.0.9, "software" sound card definitions redefine
# "default" to do mixing, meaning this device is different from "default"
and
# allows playback while blocking other sound sources (until playback
