[Zierath Bernd]

Hi,
 
as soon the non audio bit is set to 1 at reg  AC97_CSR_SPDIF there come up a error 
message in the kernel log
 
ALSA ../alsa-kernel/pci/intel8x0.c:521: codec_semaphore: semaphore is not ready 
[0x1][0x100]
ALSA ../alsa-kernel/pci/intel8x0.c:553: codec_read 0: semaphore is not ready for  
register 0x56
 
 I'm in stuck :-(

           Here's some more info of what I mean:

           I suppose the proper answer would be "IEC958 Raw"?  This would make more 
sense
        that "AC3-something" since this would apply to DTS-passthru and other forms of
        digital output.
