I've got a Sapphire Vapor-X 5770 in my HTPC and have been suffering audio dropouts during movie playback (mostly mkv's playing in 7MC, using MPC's standalone splitter and ffdshow tryouts). I had very little hair left to tear out when I found this thread and discovered this is known issue; I'd already uninstalled and reinstalled, gone from x64 to x32 OS, tweaked filters, tried DIVX.... nothing worked.

Having read this thread, I currently have stable playback of most of my movies by getting the ffdshow DXVA video renderer to kick in (THANK YOU). But that doesn't work for stuff like iPlayer (in 'TunerFree MCE').

Unfortunately you guys are way ahead of me in technical understanding. The tweaks needed to disable PowerPlay are a bit beyond me. I have created a 'No Powerplay' profile in CCC 10.5 and the XML for it (from the '..<user>\Appdata\ATI\ACE\Profiles\' folder is below, but I have no idea what values to use... any chance someone could help me here? (I am not gaming on this box, so only need movie/video playback)

I have opened a ticket with AMD too.

Thanks.
