Is it possible that your card can do either surround sound XOR full
duplex? i.e. either stereo in + stereo out XOR surround out + nothing
in?

m-h-d should load the sinks before the sources and hence it should be
handling this fine, assuming that surround is more important to you
the duplex. The sink should load properly, the source will fail with
EBUSY, but PA should continue to run just fine.

In a future version I will make this switchable during runtime.

PA should be able to handle that properly. Could you be a bit more
elaborate about what goes wrong?

This is weird. Looks like a D-Bus/CK issue.

Thanks, applied.
