After Android 6.0.1 update controlling the volume on my phone which is connected to a bluetooth device controls the volume on the bluetooth device. Before, when I changed the volume on my phone, the volume on the device still had his own volume control.
I understand, that for ease of use the merging happened - probably people disliked that they had to control two devices instead of one.
However, this means I lost a LOT of control over the fine tuning of the volume. This is a disadvantage for cases when you want to play through a bluetooth speaker a soft ambient in a low volume to fall asleep to. Now the lowest point of volume is high. Even though you can move the volume around in a non-discrete manner, you can hear, that only around 10-15 discrete volume values are used.
Is there no workaround, app, custom root modification or something I could do to switch back to two volumes instead of one?
