Wrong number of inputs reported

See original GitHub issue

After running a few times in to sounddevice.PortAudioError: Error opening InputStream: Invalid number of channels [PaErrorCode -9998] I noticed sounddevice reports the wrong number of inputs in some cases. It should be 4 in 4 out for the Behringer, as PyAudio reports.
