Don't you think that we should use SUPPORTED_FREQUENCIES_STEREO for
stereo freque

I can confirm that the problem exists. My SADs (Onkyo TX-SR605):
Forma
The current code writing SADs to the audio registers seems to assume
that there is at most a single SAD per audio format.
However, that is not the case. Especially for PCM it is somewhat common
for sinks to have two SADs, one for 8-channel and one for 2-channel
audio, which may have different supp
