thanks for the confirmation. i'll apply the patch to cvs. > By looking at your code, it looks like you are making sure the rate for > the Front, Surround and Center/LFE all change together, which seems to > work, although, the alc650 datasheet spec does not seem to mention that > this has to happen. Why have 3 ac97 registers, if they all have to > change together? we're fooled :) sometime it is explicitly written that the surround and LFE rates are simply the mirror of the front/center rate. that's why the fix came into my mind.
