what I'm trying , change no audio bit to 1 reg 0x68 in ac97_codec.c
snd_ac97_spdif_default_put().
but I get errors in
intel8x0: clocking to 48000
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 try activate the SPSA control in snd_ac97_mixer_build() like cs4205.
I also have no clue right now about the registers 0x30 and 0x34.
0x34 is maybe Codec Write Semaphore Register
