I have a similar issue, on the main menu music plays but recently I stopped getting ambient or time activated music on a realm. Music discs work for me. I was getting biome specific music regularly while working on a base that extended down into an ocean but that isn't triggering anymore either. Cave noises also play and all other sound effects seem fine, just no regular music. I'm on windows 10 and Android (same realm 2 different devices same issue) and the realm does have a few add-ons but the music worked fine when they were added so I think this was as of 1.21

No it is not, the seemingly related error still pops up on the log occasionally but the sound engine doesn't crash anymore. Thank you!

Attached contains multiple occurances. It seems to happen most often when placing cobble slabs or blocks or breaking smooth stone during an animal noise. I initially thought it was the fact that I was amassing as many chickens as I could in a 3x3 pit, so there was a constant chicken noise being played, and the engine would crash when I placed or broke a block. But I cleared it out and still had the same problem with cats or sheep, and also had it happen once after placing a torch. However, I had it happen in a creative single player world with no mobs around as well.
