[QUOTE="davidf, post: 646593, member: 19484"] Tourettes, I took a play with [URL="http://blogs.msdn.com/b/matthew_van_eerde/archive/2009/04/03/sample-wasapi-exclusive-mode-event-driven-playback-app-including-the-hd-audio-alignment-dance.aspx"]Matthew van Eerde's[/URL] exclusive WASAPI code on the Nvidia HDMI drivers and I have to admit defeat - I can't get anything to go past the initialization in exclusive mode (0x80070057). The drivers do provide proper errors e.g. 0x88890008 for formats which aren't allowed. When I try the same tests on an intel and AMD based chipset I do get my test sound outs so it doesn't look like anything I've done is wrong - and that's always a real possibility. So I suspect the drivers (at least v1.0.15.0) don't work particularly well and it may be a lost cause trying to make it work without Nvidia fixing some of the bugs in the driver. The only Nvidia machine is the main living room machine so I'll try to revert the drivers to older ones to see if any of the versions work when my wife is not using it (break TV = unhappy wife).
