Bluetooth Headset: No good block received #40

Open patricktouchette opened 4 years ago

patricktouchette commented 4 years ago

I have the following issue with my bluetooth headset. I am on Windows 10 running caster with kaldi. If I use separate sources for input (bluetooth microphone from headset) and output (Speakers hooked up to my screen), i get the following error.

...
INFO:engine:streaming audio from 'Headset (VXi B350-XT v3.33 Hand' using MME: 16000 sample_rate, 10 block_duration_ms, 30 latency_ms
...

*- Starting Caster v 1.6.16 -*
INFO:engine:Listening...
WARNING:engine:<dragonfly.engines.backend_kaldi.audio.VADAudio object at 0x000000000ED90E88>: no good block received recently, so reconnecting audio
Press any key to continue . . .

The mic works in audacity or for skype. Caster seems to recognize it, but then it crashes once the caster/kaldi engine is listening.

Hmm, strange. Not sure why that would happen, but there is an easy way to disable at least the reconnection feature: set the engine parameter audio_auto_reconnect=False. You can do this on the dragonfly or caster command line, although I forget how exactly at the moment. Hopefully that gets it working. There is also an easy way to enable debug logging, which should hopefully display some useful messages to identify where and why it is exiting abruptly entirely.

Just modify the bat file for now python -m dragonfly load-directory . --engine kaldi --engine-options "model_dir=kaldi_model, vad_padding_end_ms=300, audio_auto_reconnect=False"

List of kaldi engine parameters for configuration.
