Avatars with a number of audio sources (More than 10? I haven't tested) seem to cancel all audio currently active when the avatar loads in, including world audio and other avatars' audio that's currently active. It doesn't matter if the number of audio sources on an avatar is all active or disabled by default, if it has a high count of Audio Sources, it cancels everything else for some reason.
Wondering if there is a planned fix for this, this started happening after the latest patch with networked IK and such. Scared to use some of my avatars now in other worlds that rely on world audio since it just breaks those audio sources.
