Too high delay

[ghost]

The delay is too high, like 2 or 3 seconds

Yes, there is buffering in VLC.

You should use scrcpy (if your device runs Android >= 12).

I used it, the problem is that I only want the sound from my android without screen

Run with scrcpy --no-video --no-control if you only want the sound.

Add --no-window if you want.
