No audio on Webrtc card and HomeKit despite being present on go2rtc interface and Frigate

[IliasEagle]

Hello!

with the following go2rtc configuration for a RLC-520A Reolink camera

  Living Room: 
    - rtsp://user:[email protected]:554/h264Preview_01_main 
    - ffmpeg:Living Room#audio=opus

when I open the camera stream via the go2rtc dashboard

I can hear the audio which is also seen below

When use the webrtc card though there is no audio as can be seen below

Below is the webrtc card config

type: custom:webrtc-camera
ui: true
style: '.screenshot {display: none}'
shortcuts:
  - name: Central
    icon: mdi:light-switch
    service: light.toggle
    service_data:
      entity_id: light.lounge_central
streams:
  - url: Living Room
    name: Lounge
    mode: webrtc
    media: video,audio
  - url: ''
    name: Poster

The same applies when trying to view the camera via HomeKit

This issue is not unique to the aforementioned Reolink camera. The same applies to the Eufy Solo IndoorCam C24, 2K Also, if a camera is recorded by Frigate audio is passed to it as expected. So the issue seems to appear only on webrtc card
