Yes. PA doesn't know what to do with the 8 or more identical
channels because ALSA doesn't provide any info on how they
are supposed to be used, and ALSA is right in doing this as
there simply is no such information. The user decides how
to wire up the channels. If he wants to use channels 7 and 3
for stereo, and 8,1,6,2,4,5 for 5.1 surround that's entirely
possible, as it should be for any pro or semi-pro card.

So this could probably be solved if PA would accept some manual
configuration in such cases. Maybe it does, but so far apparently
no-one knows how to do it. I guess it's just not possible as manual
configuration sort of goes against the grain of Lennart's work. 

One practical solution could be to run PA as a Jack client. Most
people using this type of card would be running Jack anyway.



There are three of them, and Alleline.
