I tried working through your guide and did successfully get sound to come out of the tv (no receiver). This was accomplished by following the directions in this thread and setting Audio output->Analog and Audio output device-> custom (plughw:0,3) in xbmc.

However, the sound is just static, pops, and clicks. This is the case when I try to play music/videos/dvd in xbmc, when I use aplay -D plughw:0,3 welcome.wav AND when I use aplay -D plughw:0,0 welcome.wav to play through the computer speakers (for debugging purposes only). For completeness, the result is the same when I set the Audio output->hdmi and make the Passthrough audio output device be the same as the Audio output device. What is going on?

Here's all the debugging info that I can identify as relevant:

for a variety of reasons, i had to upgrade my kernel to a version from precise, but other than that, the system is fully updated xbmcbuntu.

Code:

My suspicion is that I need to edit /etc/modprobe.d/alsa-base.conf and give some option to the snd-hda-intel module, but I have no clue what the option would be or how to figure out what it is. I would really appreciate someone giving me some suggestions of things to try.
