Bug Report Error: Unknown speaker setup, no downmixer available.

[vonmatt]

I get this error message when I select my USB audio interface as the audio input. Other Windows applications don't have a problem with this audio source, for example Adobe Flash Media Live Encoder, Skype, etc.

This is a 10 channel ASIO interface, and other applications just use channel 1 and 2 (stereo signal). It would be nice if OBS could accept this audio source as well.

OBS exits afterwards (no crash file).

If you found a solution, please update! I've had this problem with multiple audio interfaces and still haven't solved my problem.

OBS has no support for ASIO audio.
