Back in August 2022, me and other players have seen Avatars with audio sources and their was a audio slider in the Launch Pad (even after new UI was introduced). It was fun until VRChat took it out for the Quest Platform. I don't recall ever crashing from audio but people kept on tell me it put too much stress on the Quest 2's GPU which I found to be false after researching how mobile apps handle the issue (it was a little different than how constraints were reworked). Anyway, I understand that if audio for the Android and iOS platforms will enable some classic trolling and crashing, but I believe the new Security Check system will heavily help eliminate issues such as frequency, audio levels, and overall memory usage. Otherwise, vrchat is just quiet and dead.
Please consider bringing back Avatars Audio and please create a Range Limit in the SDK so nobody beyond 30 meters goes blasting off audio like crazy. Might as well add an Earmuff Mode for it just in case. This specific issue has always been a problem on ALL platforms.
(Keep in mind, Unity has a ridiculous amount of versions they released, so I'd suggest checking which one does best with audio compression and quality for mobile app gaming.)
