[alsa-devel] Need help fixing pop/click artifacts in an ASOC driver

[Dimitris Papavasiliou]

I've submitted a patch for the pcm512x CODEC, that is relevant to
this problem.  The patch implements the digital_mute interface,
suppressing various clicks and pops, including the loud pop under
discussion here.  I still feel that fixing the machine driver, so
that it doesn't generate the pop at all would be desirable, as
I'm not sure whether the digital_mute callback is guaranteed to
have muted the device when the clock source takes place.

Does that sound reasonable, or would it be preferable to simply
rely on the digital_mute mechanism (assuming the patch is
acceptable)?
