The old driver configured nothing but the rate. Is there any mechanism to set the stream format?
Yes. It's AV/C stream format information command. [...] But in this series of patches, I don't use this command. I expected the models to change stream format according to parameters in AMDTP packets such like the value of dbs field.
Apparently, the firmware doesn't support automatic format detection completely, and requires this command for the 2ch 32/44.1 kHz modes.
(That 2ch at 96 kHz actually works is even more curious. There already is that bug regarding listing the seventh format; it's possible that they completely forgot to report an eighth format.)
