With pink noise you can't tell if the audio is played faster or slower.
I tested this by playing ITU speech codec test sample
aplay --device=plughw:0,7 male.wav
and audio played back on 1x speed.

Thanks for the update Mika. The issue will be that audio plays faster or
slower than normal. i.e it will be < 1x or > 1x. can you confirm if
audible sound plays after CD Clock change at 1x speed ?

Sivakumar

I tested this patch with the audio in place. With this setup in my HSW
machine I can hear the pink noise played back with DP-HDMI cable
attatched.
speaker-test -c 2 -r 48000 -F S16_LE -t pink --device=plughw:0,7

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.

sorry if i am missing something, HSW and BDW requires display audio
controller to be updated with new values once CD clock is modified. how
is this accomplished here ?
I'm hoping the audio driver will query the cdclk frequency after every
modeset.
