I just downloaded TMT3 trial version, and connected PC to AV receiver using analog outputs. Surround sound for BluRay discs does work, but I haven't found a way to adjust volume levels or delays for different channels (center + rear).

I have Gigabyte motherboard with ALC889c soundchip. Is there a way to do this somehow?

It would be in vista/win7 in sound properties of the 'speakers' output, check under control panel. Look for 'enhancement' tab. If your soundcard isn't supported by windows to use those controls, then you'll have to do a registry trick to get them to appear. Upgrade your soundcard drivers first as well.

Thanks for the tip!

...and sorry that I forgot to mention in the first post that I'm still using XP.

Yesterday I upgraded to latest Gigabyte drivers for my chip but didn't address this issue.

Any chance of getting this to work with XP?

Have you tried SPDIF to the A/V receiver?

Xp won't help you. Only if the drivers offer support for it, which sounds like they do not. Check out win7 when you get a chance.

It should be possible to somehow manage that for you.

I know you can find these kind off settings in different codecs.
For example in ffdshow audio codec you have these kind off settings to mess around whit.
But I don't know if you can use ffdshow in TMT...

Can't you make the adjustments with the A/V receiver? i wouldn't trust my HTPC to make the adjustments for me, but then I also bitstream my digital audio via HDMI. If the receiver has multiple channel outputs then you should be able to adjust the levels for each one individually. Many of them also have the ability to adjust for time delays. A home theater calibration disc, such as Digital Video Essentials, has test tones for calibrating the levels of your speakers. You may need to invest in a sound level meter like the one sold by RatShack (about $30-40, IIRC) for proper sound level calibration.
