Well, you dont seems to any luck ... no SPDIF, no rear sound -:(
Do you know which CODEC's you card have ??, are AC97 2.0 or AC97 1.03
The problem is that the secondary AC97 2.0 CODEC uses:
BA0_ACSDA2, BA0_ACCTL, BA0_ACCAD, BA0_ACCDA, BA0_CSTS2
registers, using BA0_ACCTL reigsters TC bit to address primary or
seconary CODEC.
But seconary AC97 1.03 uses:
BA0_ACSDA2, BA0_ACCTL2, BA0_ACCAD2, BA0_ACCDA,2 BA0_CSTS2
registers to address the secondary CODEC.
(about what I can understand from the bloody spec. )
The case for 1.03 CODEC's is not implemented for the moment, I got no way
to test it.

Well, but I got yet another new problem here. the /proc/asound/card0/dsp_scb
entry is to long, and now it's not possible to view all entries, the
last entries
(SPDIFOSCB, SPDIFISCB and AsyncCODECSCB) are cut of.
Any suggestion about what to do ??
