TP-Link Tapo C220 2-Way Audio Issue

[sam7567]

I followed https://github.com/AlexxIT/go2rtc#source-tapo and it seems 2-Way audio worked for many users. However its not working for me. Not sure if I am making any mistake here.

My go2rtc config:

streams:
  # TPLink Tapo C220
  tapo1:    
    - rtsp://tpadmin:<Local_Plain_Password>@192.168.5.225:554/stream1
    - "ffmpeg:tapo1#video=copy#audio=opus"
    - tapo://<Cloud_Plain_Password>@192.168.5.225                          <<-THis does load the stream
    # - tapo://tpadmin:<Cloud_MD5_Password>@192.168.5.225            <<-This does not load the stream. Cloud Password is correct

Hello, Try changing audio to AAC instead of opus, this works for me :)

Have a nice day, Azerty

And I only use the tapo:// line, not the rtsp one :)

FYI There apears to be an issue with the tapo cloud password with newer firmware https://github.com/JurajNyiri/HomeAssistant-Tapo-Control/issues/551

The correct problem with updating Tapo cameras firmware was mentioned above.
