Ah, sorry...  Should I have been listening on an analogue input on
my receiver instead?  Ok, switched...  with -Dhw0,1 on an analogue
port (and keeping VIA_DXS_SRC) I hear signal.  My settings are:

Also get signal with -Dhw0,0 on an analogue port...


(Still the same warning about the rate mismatch, though...)

I tried not changing ac97->rates[AC97_RATES_SPDIF] at all, but that
didn't make any difference...
