If you are using multi channel audio equipment with 24-bits, try to avoid FULL-speed ones!

Well... first I want to get the 2 channel 16bit case working... then I will have a look at extending this to 5.1 (most probably 16bit, that's enough to watch action movies).


Some more ideas:

2 channel 16 bit will only work if you turn off bitperfect. The lowest number of channels the device exports is 4 for playback. That means the kernel will re-format 2 channels to 4 channels always and that is done by the PCM feeder. You'll need to check that there is a filter which handle that.

You might want to install virtual_oss from ports to handle this device properly.
