Going through my system logs after restoring from backup. AFIK, do not have a problem to solve related to audio.
I found the audio log (below) with this entry near the bottom,
> “Most likely this is a bug in the ALSA driver ‘snd_bcm2835’. Please report this issue to the ALSA developers.”
So that’s what this is. If you know a better place to report, please let me know.
Log follows.
