where can i check this (audio driver) ? since there was no need for them
to check CD clock value till now i don't think they will be doing it.
also this needs to be changed in Display Audio controller, so not sure
if audio driver has access to it in the first place. will be good to
confirm this before merging as it will break display audio if it is not
programmed.

if any one has setup this can be confirmed by just switching CD clock
after boot and playing an audio file.
