[mythtv-users] Audio on HDMI - Need more suggestions

I have a new installation of MythDora-12, works pretty well, but I 
haven't gotten audio onto the HDMI wire yet.  The PC has an Asus 
motherboard with nvidia built-in sound, the video board is an 
nvidia-220.  I followed this tutorial (which is pretty good):


It looks like everything is right, but still no sound on the HDMI 
connection.  So far:

- built and installed alsa-driver from source
- added "enable_msi=0 probe_mask=0xffff,0xfff2" to 
- created this "/etc/pulse/default.pa", and put "load-module 
module-alsa-sink device=hw:0,3" into it
- unmuted the s/pdif device with alsamixer
- added user mythtv to the audio group
- changed mythtv "audio output device" to ALSA:plughw:0,3
- sound works through the regular speakers
- this test runs "speaker-test -c6 -twav -Dplughw:0,3", but nothing 
comes out of the speakers

Anyone have a suggestion on what to try next?  By the way, is 
pulse-audio needed for this...everyone seems to talk about it, but the 
tutorial barely mentions it.

PS - ...and I got this from aplay -l
