In my device, clock to the codec is coming from modem (for voice call use case). After voice call termination, application Calls snd_pcm_close for voice device and then turns off the modem clock. Since clock is turned-off while Widgets are still on (power down deferred by pmdown_time), I am noticing the glitches.
This clearly isn't something that should be set in the CODEC driver, it's a system integration issue - on a different board there might be no such requirement.
