Sorry to post again but the new forum annoyingly scrolls my screen involuntarily when the message gets so long (can't see what I'm typing), so this is just a post to list some of what I've tried:
(Computer is using Windows 7 SP1 btw.)
-Tried disabling the on-board audio (both digital and analog outs). Problem persists.
-Tried changing every driver setting you can think of. What I found is if I disable exclusive mode (i.e. WASAPI) on the HDMI output, it does
eliminate the problem. However it creates two other problems!
One is that the audio gets down/up sampled to whatever the driver is set at for default output and doesn't use PAP I'm assuming (I'm thinking this is what it *always* did with the 4830 because I don't think it supported un-resampled output?). That one is not a big deal. However what is a big deal is the other problem.
The other problem is when I do that, for some unknown reason, it does NOT send the LFE signal (clearly the sub isn't outputting anything and the LFE level indicator on the receiver shows no activity). I have no idea why it does that because it never happened with the 4830. Disabling exclusive mode also prohibits me from using WASAPI streaming when using an audio player and playing [2ch] music (which I do quite a lot from this machine).
-Then I tried changing the HDMI driver up, thinking that if I tried an older version it would work right since I never had any problems with the 4830, audio-wise. I think the latest one is Realtek 2.67 or something. Went back to the driver before (Realtek 2.55) and nothing. Luckily I still had my old HDD with my OS intact, from before I switched to an SSD. So I looked up what driver version I had on the files on that drive (which would be what I had with the 4830 in there). So I went back to that driver (which was the one before 2.55). Again THE SAME STUPID PROBLEM!!!
I don't get it...it can clearly playback the audio fine, so where does this moronic pause problem come from?
When I pause, the audio stops (as it should) but then unpausing it's the horrid noise and then you can't recover from that until you either re-start TMT or switch the audio output type up (but you can't go back to LPCM anyway or it's the dumb noise again).
So at this point I think I've tried just about everything I can think of. Changed drivers, changed every setting imaginable in TMT and Windows, disabled this and that...I even tried using the ATi DVI-HDMI adapter I was using with the 4830 (because it didn't have a native HDMI port) on the DVI port of the 6750, and the audio behaviour is exactly the same. In summary BD playback in TMT3 is totally broken (stuttering) and it's nearly useless in TMT5 (loud noise)...all from going from a 4xxx series to a 5xxx series.
I've seen this referred to as the "pause bug" in a few threads I've searched, but nobody seems to have posted a solution? I'm hoping someone else here has been able to fix the problem? Any help would be appreciated!
