It's difficult to offer any specific advice for the CODEC without any
visibility of either the hardware or the driver. In general you want to
look at what happens to the hardware when the playback has problems (do
any clocks stop or anything - presumably there is some hardware
change?), then work back from there. Might be worth trying suspend and
resume with playback running to see if that has any impact too.
It's possible that there is an issue in the CPU driver as well, I don't
know what the testing status is there. Things like suspend and resume
during activity won't always get tested, and your case with record
running is definitely fairly obscure.
