thanks, mainly keep an eye on the audio hickups and "broken pipe" log messages you initially reported - I think current nightly builds should be fine now though.
Tbh didn't check logs for this but usually when there was a sound problem I could hear it right away. I'll try to check the log next time.
There seem to be occasional audio glitches with HD audio passthrough (which won't show up in logs), we are looking into it but so far I could not reproduce those here.
with the build you gave I could not hear any issues, sound was perfect all the time.
HDR output issues, like banding in the clouds, are also known - fixing those will take a while, kodi and video driver are currently missing several important bits and pieces.
understandable. Tbh it's much less annoying that sound going away in battle scene
