Hey there everyone, I just had this problem and stumbled upon this post. I wanted to let you guys know of a possible fix: I went back to the cave where teh Netflix Quest begins, and the music ends and sort of "fixes" itself.

However, if you die or load another save, that damn music continues, so I don't know. I might try the sewers in Novigrad to see if it fixes stuff for the rest of the game. The cave method seems to work until the next game reload tho.

thank you very much I had the same problem and when I entered Vizima the music went back to normal

Got the same issue, just noticed that when i played tried to play Gwent, nothing plays, going to combat, nothing too, it always plays the Devil's Pit exploration music, instead of literally playing anything

Edit: going to Novigrad sewers actually fixed it, bruh, they better fix this

The workaround also seems to be permanent unlike Vizima fast travel which only temporarily fixes it, so rebooting game / loading saves doesn't make the game plays Devil's Pit music anymore

Edit 2: The issue is back once you arrived in Skellige. Will report if the sewer can fix again.

Edit 3: The sewers are unable to fix the bug, but going to White Orchard (specifically the Nilfgard camp) fixes the bugged Skellige music.

I have the same problem, it started when I was playing the game on PC (GOG) and some time later I wanted to continue on my PS5 and the problem got transfered there too, so now both PC and PS5 versions only play that creepy ambient music from Devil's Pit. Going to Visima solves the problem untill I die and have to load from any save.
