I think it basically comes down to lack of documentation about the chips.
The sound cards that work well in linux have one of two things: -

1) good specification documents.
A lot of manufactures seem to publish specification documents for their 
chips, but very few of these published documents are complete and 
accurate. I have not found any AC97 chip yet that has full details on 
how to set non-audio bits on the SPDIF, although the chip manufacturer 
has published specification documents for the chip. E.g. Realtek ALC650.

2) Someone with the time to tinger about and discover how to do it.

Cheers
James
