We've got a new VRChat patch out for you. This is VRChat 2021.1.5p3, build number 1078.
It is a small patch that implements a workaround to mitigate the voice-breaking "audio bug"!
Changes, Fixes, and Additions
- Implemented a workaround to help mitigate the "audio bug". It should no longer kill your voice audio until you restart VRChat, but instead will only result in a ~1-2 second cutout. We're continuing to investigate to address the root cause!
