Strange bluetooth artefacts in audio connection

Show all headers | View raw

I'm trying to use blutooth to stream music from a couple of Android
devices using VLC for Android as the player.

I'm getting several strange (and annoying) effects when doing this,
these are definitely down to the Bluetooth connection as a direct
wired connection works without showing any of these effects.

The problems are as follows:-

    There's a strange sort of 'whoosh' noise at the start and end of
    each track.

    If you turn the volume up the sound breaks up completely (turn up
    at the amplifier that is).  The amplifier *isn't* being overloaded
    so I really can't understand this effect.  How does turning the
    volume up at the receiving end affect the sound?  It's not
    clipping or anything, the sound is overwhelmed by what sounds like
    a noisy volume control.

    On one device (Moto E, Android 5.1) the connection drops
    completely for a few seconds at varying intervals.  Moving the
    Bluetooth receiver about doesn't seem to make any difference.


I would emphasise that these problems are *only* when playing via
Bluetooth, there is no 'whoosh' when directly connected and I can turn
the volume up to painful levels without significant distortion.  The
noises occur on both Android devices so it wouldn't seem to be a fault
on just one of them.
