A more general question: Who has gotten multi-channel in ChucK working under windows XP? What brands/models of soundcards?
Well, yeah, that's a good question too. I had sorta kinda asumed that if nobody complained it should probably work generally. I know for a fact that the EMU's used to have issues with non-asio multi channel. EMU tried to get out of it saying they were "professional cards", then there were lots of complaints from people working profesionally on DVD's and it's supposed to be sorted now.
Does winamp have the option of using DirectSound as the output (the primary sound driver belongs to winmm, I think)?
In fact Winamp does. I got one six channel wave file for testing and in winamp the "primary sound driver" works perfectly that way. The DirectSound one stripped it to the first two channels (no down mix). This bothered me a little but chuck --probe doesn't mention any Direct Sound and does mention the "primary sound driver" so this is why I started to suspect ChucK might be to blame. I'm starting to suspect the Windows "consumer" sound standards are a little bit more of a jungle then they pretend to be. Still; there must be some straightforward way because I think these days you get a surround system aimed at wintel computers for free with three boxes of cereals. I have no idea at all how those people make sense of this stuff but seemingly they do. Kas.
