direct x sound

[GrandpaTrout]

I am messing about with sound channels in EoC and could use some assistance (ideas).

EoC supports streams of audio, and I can get the first 4 channels to play on my system.

Does anyone know how to tell the number of audio channels are supported by the hardware and drivers?

I am trying to tease out if the number of audio channels is fixed by hardware, or hard coded somewhere in the Flux (EoC) engine.

I have run DxDiag and it does not show the number of supported channels.

Thanks in advance for any advice on how to find an answer....

AFAIK Edge of Chaos supports Directsound 3D, which should mean that at least 4 speakers are supported.

Sorry, I think I was misleading. What I was trying to say was *input* sound channels. They get mixed in the sound card and output.

Flux uses the Stream package to get to Direct X like this

Stream.Play( int slot, string url, bool fade, bool loop );

That first argument (slot) is what I am trying to pin down. On my system I get the first 4 channels (or slots) to play, but no others. I wondered if other systems would get more (or worse, less) of these channels.

I think only 4 channels are supported in Pog.
