Talk via HomeAssistant Frigate hass-card microphone.#389

I'm using Neolink talk command with a non-doorbell reolink camera. This test command works, `ffmpeg -i https://rhasspy.github.io/piper-samples/samples/en/en_US/lessac/high/speaker_0.mp3 -f alaw -ar 8000 -f wav - | ./neolink talk front_door -c config.toml --volume=1.0 -m -i "fdsrc fd=0"` as I can hear the camera speak the arbitrary audio file. Two-way audio does work with this camera using the official Reolink mobile app. So I would think that Neolink should be able to do this too. I am running Home Assistant (supervised with docker) with the Frigate and Neolink addons. (_I still need to find out how to have ffmpeg/gstreamer preloaded and persistent across docker/addon restarts_). But I am now trying to get my frigate hass card with the microphone button working. I'm on the HomeAssistant Android app, and pressing the microphone button highlights it red, I speak into the phone mic, but no sound comes out of the camera speaker. ``` go2rtc: streams: cam_backyard: - "ffmpeg:http://10.0.x.x/flv?port=1935&app=bcs&stream=channel0_sub.bcs&user=admin&password=PASS#video=copy#audio=copy#audio=opus" - rtsp://admin:[email protected]/Preview_01_main cam_backyard_sub: - rtsp://admin:[email protected]/Preview_01_sub - exec:/config/neolink/neolink_talk.sh#backchannel=1 cameras: cam_backyard: ffmpeg: inputs: - path: rtsp://127.0.0.1:8554/cam_backyard input_args: preset-rtsp-restream roles: - record - path: rtsp://127.0.0.1:8554/cam_backyard_sub input_args: preset-rtsp-restream roles: - detect ``` /config/neolink/neolink_talk.sh --> ``` #!/usr/bin/env bash ffmpeg -fflags nobuffer -f alaw -ar 8000 -i - -f wav - | /config/neolink/neolink talk Driveway -c config.toml --volume=1.0 -m -i "fdsrc fd=0" ``` I am looking for documentation, tutorial or guide that describes how it is "supposed to work" with a Reolink camera.
