Been stuck trying to figure out a solution to this problem...


I have a Windows 7 (Pro 64-bit) bases HTPC I built around a Ceton tuner, Intel Celeron G530 CPU w/ on board GPU/digital audio out, and ECS H61-H2-M2 motherboard with HDMI out. In control panel, I configure my speaker settings as 5.1 surround (side surrounds) w/ full range fronts, and set the audio output quality as 24-bit/192 kHz (so I can enjoy music from HDTracks.com that I stream from my NAS to XBMC).


The problem I've run into is that sometimes randomly, sometimes when I restart Windows, and sometimes watching TV in MCE with Dolby Digital audio bitstreamed to my receiver, and maybe when the HDMI handshakes, my audio output preferences get reset back to the default 16-bit/48 kHz stereo. Tried turning off exclusive mode to stop Dolby Digital bitstreaming, but that didn't help. Is this something to do with the HDMI output, like it's seen as new each time and thus uses the default settings? I can't think of anything else.


What's the best way to fix this? The only thing I want to avoid is anything that would lead to the first second or two of audio being cut off when I start playing a song in XBMC because the receiver has to lock in on a format change. Ideally, I'd like the HTPC to always output 5.1 24-bit/192 kHz, up sampling lower quality audio and/or leaving the surround/center/LFE channels silent on stereo sources. Bitstreaming everything would cause the aforementioned hiccup I don't want.


Thanks!

Do you ever rdp (remote desktop) into that machine from another one? I ask this because I used to rdp into my HTPC to do maintenance and such and it would always reset my audio to 2 channel, etc. Only thing I can think of.

Nope.


Consulted with some people who agreed the HDMI handshake seems like the culprit. Getting a Gefen HDMI Detective from Amazon to see if it fixes that and some other HDMI issues I have.
