In addition to the mask the test should also not be against using_channels
(which specifies the current output), but rather stream_channels (which tracks
the input stream channels).  The original patch would repeatedly renegotiate if
e.g. downstream could only handle 2 channels (using_channels) of the 6 input
channels (stream_channels).
