Along with the other volume settings like menu sounds and sound effects, allow audio sources attached to avatars to be volume-controlled as well
This is a good suggestion. We should also add the same limiter tech to the avatar sounds to keep volumes within acceptable ranges.
Wanted to add that there should be an absolute limit on the range of avatar sounds. Nothing more annoying that having a convo and someone next to you rocks out some music from their avatar you don't want to hear. Rooms should also have the ability to disable avatar sounds.
