**Describe The Problem:**
After updating to [v6.1.0](https://github.com/hjdhjd/homebridge-unifi-protect/releases/tag/v6.1.0) the audio is missing. Rolling back to [v6.0.3](https://github.com/hjdhjd/homebridge-unifi-protect/releases/tag/v6.0.3) resolves the missing audio.

**To Reproduce:**
Update to v6.1.0+ and view the camera in the Home app.
