The volume of my ST 300 does not synch with the Bluetooth device. While the ST300 is connected to any Bluetooth device, if I increase or decrease the volume from the ST 300 remote, it does not affect the volume of the source device. The volume goes back to the same volume as set on the source Bluetooth device as soon as the new song starts. However, if I change the volume on the source device (phone or iPad) it continues to work on the same volume as set through the source device. I started facing this problem after a certain ST 300 firmware update. I am using an iPhone X with latest software.

Firstly, can you please confirm if you have attempted any troubleshooting so far on the SoundTouch 300 Soundbar? Also can you please let me know what streaming service you are using when attempting to connect to the system?

I tested on Amazon music and Gaana. It behaved differently on both. Having said that, in both the cases, the remote did not increase or decrease the volume of the sources Bluetooth device. Earlier when I changed the volume using remote, I could see it changing on the source device as well. Now if you decrease the volume from remote and then unlock the device the volume goes back up all of a sudden which is irritating sometimes.
