hdmi audio stopped working after last update

I have a (7th gen?) NUC worked fine for years. Plugged into TV for HDMI audio & video.

SInce last update 2-3 days ago the audio is not working.

In the GNOME settings it says 'no sound'. I can see 'HDMI audio' as the output device on the login screen, but can't adjust the volume there.

aplay seems to know about the HDM audio outputs:

root@gronk # aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC283 Analog [ALC283 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Not sure how to proceed here. Can somebody suggest anything?

Thanks
Patrick

Well, reinstalling everything fixed it.
