So I have had this problem for around a month and I have tried everything but I can not figure it out. So I can start up OBS or OBS Streamlabs and start up a game and sometime's when I start up the game I lose all audio broadcast to OBS even though it shows on the meters it's registering it but you can't hear anything on my page i'm streaming to. So then I have to restart pc to get it back and sometime's that doesn't even work. Also it could work fine but as soon as I have to Alt Tab out to fix chat or something I lose all audio again and forced to stop and restart. Please someone know the fix.
