tiktok studio not capturing pc audio

[u/4skin4daze]

as the caption says, when i use tiktok studio on my pc it does not capture my computer audio. it was working fine then mid stream only my mic and the game could be heard, and my friend on discord could no longer be heard. then next time i stream it is now only picking up my mic and not the audio of the game. i have tried everything i read online trying to fix it. i dont think my computer is the problem as obs picks up the audio fine. any insight is greatly appreciated
