Bluetooth speaker volume very low with Z U

[SunnyEricsson]

 have a TDK Trek Bluetooth speaker which as work very well with Z Ultra (and ZR and even Ray).

A few days ago the TDK speaker volume is very faint compared to before, and despite checking all volume related switches it remained the same.

The ZR is working fine with the TDK speaker.

However there is no problem with the Z Ultra volume when connected to a bluetooh headphone SBH80.

Has anyone experienced this?

Hi,

Have you tried to remove the pairing between the devices and try to connect them again to see if same behaviour appear?
