ALSA   : alsa-driver-1.0.8, alsa-lib-1.0.8 and alsa-utils-1.0.8

with au88x0_iec958.patch ( replace SPDIF SR control by IEC958 control )

store/restore /etc/asound.state by alsactl /etc/modules.conf

post-install snd-au8830 /usr/sbin/alsactl restore 0
pre-remove snd-au8830 /usr/sbin/alsactl store 0
