Hey there, I've been having issues with the sound in this game, similar to what others mentioned - the sound works during the opening sequence/intro, but not in the cutscenes, main menu background music, or sound effects.

Some places suggested to ahead and start the game, then pause and adjust sound, and THEN the sound would work, but that didn't work for me
(Other thread from that https://gtm.steamproxy.vip/app/1225570/discussions/0/3800525036432420861/ )

What I eventually did find to work for me was to go to the
- Host Machine of the Steam Remote Play
- Steam > Settings > Remote Play > Enable Advanced Host Options
- My "Enable Hardware Encoding" was checked, and the "Enable Hardware encoding on NVIDIA"

This is the ONLY game that I have had issues with in regards to this, and all other sounds are still working fine through Steam Remote Play's connection

I also will be turning this Hardware Encoding BACK ON whenever I'm not playing Unravel Two, since it means that my graphics card's quality and remote connection in particular are MUCH better and smoother.
