Was playing in an online multiplayer game when the sound started glitch, for both me and the other member in my game. Certain sounds were working and some weren’t, then occasionally all sound was lost. The music and all other audio was fine in singleplayer, and in the main menu.
We tried quitting a few times, and it worked once but only for a few minutes, then the sound was lost again for the both of us. Both of our connections are very strong, with the appropriate channels open.
