WebRTC Error using stt.cloud_say on a webrtc stream

Since HA 2025.8 i can no longer send a text-to-speech to webrtc media player. i get the following error log. This has previously worked without any problems.

I have tried this on WebRTC v3.6.1 and v3.6.0 (in case it was the recent version which broke it). Same error in both

It's not a fact that it was the update that broke it. Maybe it's just a cumulative error in your camera. Maybe the go2rtc update affected the error.

There is no reason for the error in the log above. Just the fact that it exists.

It needs a detailed description of all your configs. Information about the camera. Logs. And stream info/probe from go2rtc WebUI.

Apologies AlexxIT, i should know better than that. Yes the error in HA system logs did seem pretty useless. In fact, I think this might have started after the recent frigate update so perhaps the go2rtc binary update as part of 0.16.0.

I have an Amcrest AD420 doorbell, configured through frigate below. i use a few custom:webrtc-camera components in the dashboard. One as a preview, and one fullscreen with 2way communication. These are still working fine, even 2way comms.

So, the only thing that stopped working is the TTS convenience buttons for "please leave the parcel" etc.

I can't seem to access the go2rtc ui on port 1984 at the moment. I'll have another look at that when i get home, but i've included the go2rtc logs below. What shouts at me is the RTSP/1.0 401 Unauthorized response which immediately follows the TTS POST request (log: 2025-08-27 15:38:40.205723103)

Looks like go2rtc run ffmpeg for transcoding MP3 from HA to PCMA. And immediately closes the connection to the camera. It doesn't like something.

You can add separate stream with only rtsp link to your camera (remove ffmpeg for audio transcoding). So logs will be cleaner.
You can increase log level to trace for all modules. Maybe there will be something useful.

Thank you, i really appreciate your help with this. I know very little about streaming video/audio.

I added custom_components.webrtc: debug along with changes below and ran another test with the direct rtsp stream as suggested. Same problem, but i'm unable to find the debug webrtc component logs. Have included go2rtc logs below.

Looking at it, it still seems to be setting the source to ffmpeg. Please let me know if there is more information I can collect from somewhere

go2rtc config (in frigate)

note: other streams in previous post still exist, this is in addition

go2rtc:
  log:
    level: "trace"
  streams:
    doorbell_talk:
      - rtsp://admin:[email protected]:554/cam/realmonitor?channel=1&subtype=0#backchannel=1

webrtc entity

media_player:
  - platform: webrtc
    name: Doorbell Talk
    stream: doorbell_talk
    audio: pcmu/8000

I have similar assertion issue for a long time. It looks like WebRTC is not fully initialized after HASS restart. The WebRTC telegram services do not work and produce the same assertion, and media player entities are not available. When I open the HASS page with WebRTC card and let it play the video stream, then all media players are initialized and error is gone. Tried to fix this by calling webrtc.reload service after startup but it did not help
