Describe the problem you are having

When i play the live video stream in VLC all is well.
However, when i play the stream Home Assistant or Frigate, I do not get audio in the live view (web gui) or recordings.

Logs do not indicate an issue. tried to play it using Go2RTC plugin in home assistant, this is the below probe i get.

Any other information that may be helpful

I see from ffprobe, that it is mpeg4/h264, not sure if that means i should change my config to mpeg4

Your go2rtc line isn't copying or transcoding audio. Depending on what kind of audio your camera is sending, you may need something like:

#audio=copy#audio=aac

Check the docs here.
