Blenshape names error after opening saved .USD file

I am experiencing a bug identical to the one described in this post.
After loading saved file I get 2024-03-22 12:58:58 [Error] [omni.audio2face.utility.scripts.utils] [StreamLivelink] the BLENDSHAPE NAMES input is empty. Please connect or enter a valid input before activating the streaming error.

I am using Audio2Face 2023.2.0.

Hi! I did connect it, however, the problem persists. Is there a temporary workaround?

Thank you for your reply.

Also, the problem is solved only after I click “Send example track” in my Streaming Audio Player, but as I want to run it in Headless mode, it is impossible to do so.

The workaround is to play some audio, then you’d be able to activate the StreamLiveLink.

If you’re using Streaming Player, you can right-click and send the example track.


And if you’d like to do it using REST API, you can send a very short audio to Audio2Face, then activate the Streaming like so:

    # send a very short audio to audio2face
    push_audio_track_stream(url, data[:10], samplerate, instance_name)
    # enable livelink
    enable_livelink_data = {
        "node_path": "/World/audio2face/StreamLivelink",
        "value": True
    result ="http://localhost:8011/A2F/Exporter/ActivateStreamLivelink", json=enable_livelink_data).json()
