I had a NUC media server running Kubuntu and Kodi v18, and HDMI passthrough was working well. Recently upgraded to a new NUC that came with Windows 11. Installed Kodi v18 so that I could copy my settings over from the old NUC - all went well, HDMI passthrough also working.
But with the new NUC, I'm getting intermittent (like once every ~20min) audio issues where the audio sounds like... Difficult to describe. It's tinny and robotic / digital-sounding, like a phone call with poor reception, or an mp3 with an extremely low bitrate. After a few seconds, it goes back to normal. Things I've tried:
Kodi audio settings:
Passthrough audio goes from HDMI into the TV, then out of the TV via optical into a DAC. But I'm fairly certain the DAC isn't the issue, as it works fine with the old NUC.

It's tinny and robotic / digital-sounding, like a phone call with poor reception, or an mp3 with an extremely low bitrate. After a few seconds, it goes back to normal. Things I've tried:
- searching the forum for answers, obviously - most of what I've found just says to set the Passthrough device in Kodi to WASAPI, which it is.
- swapping HDMI cables
- upgrading to Kodi v19.5.0
- rewinding to the same sections of a video - the glitch does not repeat on the same sections
- trying different video files - seems to happen across files of various encodings and various audio streams
- trying DirectSound as the passthrough device
Kodi audio settings:
- channels = 2
- output config = best match
- maintain volume on downmix = True
- resample quality = high
- GUI sounds = never
- allow passthrough = True
- passthrough device = WASAPI:HDMI - SAMSUNG (2-HD audio driver for display audio)
- all mutli-channel capabilities disabled (AC3, DTS, etc.)
