Audio not streamed with sample_video.py

[vli-syngular]

Hello, I'm testing with sample_video.py. All sensors data can be streamed except the audio. Am I missing something?

Hi, Audio playback is not implemented in sample_video.py.

Then is there any example demonstrating how to stream pv and extended audio at the same time?

[jdibenes]

There wasn't but I just added an example in sample_pv_audio.py

[vli-syngular]

It works well! Thank you so much for adding this example.

Did you ever try using StreamingCaptureMode.AudioAndVideo to achieve that? Though I suppose your current solution is better in terms of performance.

I tried it a long time ago. When using Exclusive capture, the audio controller would report 11 channels but the callback would not receive any audio frames so I didn't continue down that path.

Thanks for sharing those findings

Any idea how to eliminate the echo? I've tried changing MediaCategory::Meida to MediaCategory::Communications in c++ project, which will use sample rate 16000 instead of 48000, but then the microphone capture cannot be heard.
