2-way Audio

This card supports 2-way audio (e.g. transmitting audio from a microphone to a suitably equipped camera). In general, due to the myriad of different cameras, security requirements and browser limitations getting 2-way to work may be challenging.

Requirements

Environmental requirements

Must have a camera that supports audio out (otherwise what's the point!)
Camera must be supported by go2rtc for 2-way audio (see supported cameras).
Must be accessing your Home Assistant instance over https. The browser will enforce this.

Card requirements

Only Frigate cameras are supported.
Only the go2rtc live provider is supported.
Only the webrtc mode supports 2-way audio:
Must have microphone menu button enabled:

Usage

The camera will always load without the microphone connected, unless the always_connected microphone option is set to true.
To speak, hold-down the microphone menu button.
- On first press, this will reset the webrtc connection to include 2-way audio unless always_connected has been used.
- Thereafter hold the microphone button down to unmute/speak, let go to mute.
The video will automatically reset to remove the microphone after the number of seconds specified by disconnect_seconds configuration have elapsed since the last mute/unmute press.
