I have a Sony Xperia Aqua, and when it was running Lollipop, when I connected to my car stereo via bluetooth, it used to be all music and really quiet vocals. I realised that the phone was set up for surround sound, changed it to stereo, and this fixed the problem. I've just upgraded to Marshmallow, however, and am having the same problem, but this time I can't work out how you switch from surround sound to stereo. Any pointers?
