Try it ingame, go into 1.20 and break blocks, listen to music discs, and etc. It will sound completely normal. Hop into 1.20.2+ and the audio is muffled, and sounds terrible. This is not an issue with my device, as my audio in other games, videos, and media sounds normal. I hope this gets resolved in the next snapshot, or in a small patch because the audio is noticeably worse.
