Blue tooth connection falters and stoppped

[Jacq1]

Hi,

Two weeks ago Spotify was doing fine with a blue tooth connection to my Sony Audio system/speakers.(about 4 meters away)

Now no more music, sometimes just a crackling sound. Unless I take my desktop (Win 10/64) next to the speakers, then the connection is fine. If I move one meter the connection is very bad and then gone again. I switched off WiFi that might block the signal, no result.

Any ideas how to solve this problem?
