Hello @katawful, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/718#issuecomment-884554766.
proton 5.13-6x1 2021-07proton 6.3-5x1 2021-07
Problem:
On Proton version 6.3-5, the music to this game skips every 5-10 seconds to the next track in the music queue
Steps to reproduce:
Install Oblivion from Steam normally, making sure that Proton 6.3-5 is the Proton version use. Set up graphics setting as you like and then play the game. Music will skip repeatedly when in-game. Proton 5.13-6 does not have this problem
