I bought car holder for my Note Pro to listen music from it and use it as navigator.
I noticed that volume level is very weak over Bluetooth (I connect my devices to my car speakers over BT) when compaired to my Note 3. NP is same loud on max volume what Note 3 is with 3/4 volume. So max volume leaves too low (I have to trun so much volume to my car radio that I'm terrified of blowing up my aplifiers, since I have never turn volume so loud when using USB, radio, or Note 3 over BT).
Is there any way to boost that volume up, to get it at least same level as Note 3? I got rooted tablet, but no custom recovery or so.
I found somewhere that editing mixer_paths file, you can increase volume levels, but only for speakes and headphones.
So any help is welcome
