to eyagos:
the above modification was recommended to me by the author. it was working with 3528. its not working with 3529. can you check it with your setup? i will try your suggestion if i have free registers
to Daniel Drummond:
my tvaudioout is connected to my linein. the volume is ok. your suggestion will disconnect my ac3 sound then right?
i like the above modification because it does not disconnect any other feature. like ac3 sound and etc.
it just adds In0 and In1 to RO_rear_r and RO_rear_l everything else is by default.
