Could you confirm that this workaround is still necessary for the latest code? We switched to the write-sync on the recent Intel chips, and this may already cover such errors.
thanks,

Thank you. We cross checked with latest code and specifically applied the below commit: ALSA: hda - Fix intermittent CORB/RIRB stall on Intel chips
Now, we see suspend & resume time significantly reduced. So, current WA patch is not needed.
