Well, I'm in the Linux impared category, failing badly in my attempts to get the log files out (not giving up yet)... however, while fumbling with this I noticed something weird...
audio is setup thus
Audio output : HMDI
Speaker Config : 5.1
Boost volume : enabled.
Dobly Digital AC3 : enabled
DTS : enabled.
Audio output device : HDA NVidia hdmi
Pasathru output device : HDA NVidia hdmi
this is what, after a reboot, will play MP3 & AC3 audio all day long, but the first time you play a DTS track, all audio is lost till a reboot (no error message on screen, just silence)
Now, here's the odd thing.. whilst going thru some permutations... I noticed some duplicate(??) entries in the choice of devices?
For auto output, with the selector starting at "Custom" then clicking to go thru them
Custom
HDA NVidia hdmi
HDA NVidia Defaults
HDA NVidia hdmi
HDA NVidia iec958
HDA NVidia Defaults
hdmi
iec958

Custom (back where started)
for passthru -

multiple entries? as I said this is a Asus M2N board w/onboard audio and a Galaxy 210 card... now from what I can gather reading about... this is pertinent info? (I said Linux impaired here)

I tried some variable things I saw on other comments... plughw:1,3 and such... no change in behavior, except when it didn't even initialize audio.
Just for giggles, I tried a Radeon 5450 card I had.. and using the hdmi:CARD=Generic posted elsewhere.. It flipping worked properly!
Except the displayed image was shrunk by about 20% leaving a 2" wide window-boxed around the picture (47" Vizio).... close but no cigar...
I shall find a proper FTP program or something and get those logs yet
but if any of this points anyone anywhere I may have overlooked.. PLS LMK!.
addendum: I thought that the onboard audio of the board might have been confusing things.. so I disabled it and..... (again cycling thru the options)

no mention of NVIDIA drivers at all? and nothing would produce sound in any form (either silence or 'unable to initalize drivers). the aplay did show the 210 as CARD=NVidia but that made no difference either...
