David, were the "suprises" pleasant or unpleasant?
Ha, of course I meant "surprisingly good" results, with little to no clicking (but sometimes occurring with even moderate DSP cpu loads)
I ran the code with my onboard NVidia AMD nforce4 ac97, a Roland ua-1a device running "USB composite device", and my Terratec EWS88MT's extra output (fixed at 48 Khz) - not the full 12/10 combo which doesnt appear. cant try my various SB cards, because of lack of working drivers.
I'm trying to put latency down, but i got tired of shooting in the dark with trying things. Thats why i'm awaiting answers before continuing. Knowing that vista is now scheduled to release in 2007, its not that urgent it would seem. The way it currently works is a bit odd, with the 100-nano second "periods" settings, which cant seem to fit on even sample frames in some circumstances, or .. sigh allow for power of two sized buffers.
Also since no pro audio card has Vista drivers yet, my biggest gripe currently is not knowing if its possible for a device manufacturer to define a huge 16 output (or more) endpoint in one IAudioClient without having to fake it with WAVEFORMATEXTENSIBLE's nChannels set to 16 and dwChannelMask set to 0x00, or to have that manufacturer define a bunch of separate stereo pairs to do the job.
(i never implemented WDM-KS's pin querrying stuff mind you - so might be a similar thing)
I've got another bag of questions...
