I posted about this in the 3D HTPC thread, but I'll ask here: I am getting massive and horrible audio issues with TotalMedia Theatre with the Tron: Legacy 3D blu-ray. The audio will pop and de-synch completely after about a minute. It's especially noticeable in the Pirates of the Caribbean trailer and in the disc battle. I've tried multiple audio settings, and even different outputs, but I get the same results no matter what.
I'm running: Athlon X2 6000+, 4 gigs RAM, Radeon HD 5870, Audigy 2ZS all under 64-bit Windows Vista Ultimate. The sound issues crop up regardless of whether I use the HDMI audio-out on the Radeon, 5.1 output through the soundcard, or SPDIF output through the soundcard (using PCM, DTS or Dolby Digital downmixing).
I don't get these audio issues with PowerDVD 10, but I do get some really nasty video artifacting, so that's no good either.
Anybody have any ideas? I've tried TMT 3 and TMT 5 and it's exactly the same on both. I'd prefer not to have to upgrade my video or my sound card (of the two, I'm more amenable to a sound card upgrade, though). I'm tempted to install the copy of Windows 7 that I've had for a while to see if that will ameliorate any of my issues, but I don't want to waste the time doing an OS upgrade if there's some other issue at work here that might have an easier fix.
Just tried 'Cloudy With a Chance of Meatballs' and I'm seeing the same audio problem. Presumably this effects all Blu-ray 3D discs.
