I have suddenly no sound after the january 2018 update (for reference I was one of the early testers of the stretch so I migrated to that some months ago).
in dmesg I have a lot of muting going on?!?

aplay -l looks normal:
osmc@osmc:~$ aplay -l

Anyone else with same issue, or is it just me?
SOLUTION: turn off and clean a bit, maybe related to something touching gpio22…
