So with my Evo 4G I had great sound quality when playing music through the bluetooth in both of my cars. Now with the Evo 3D sounds like crap, its all quite and has no bass or mids sounds like all treble. I've downloaded a app called Bluetooth Volume Lol that didn't do anything at all.
Anyone have any ideas? The only thing I can think of is I was running the latest Fresh rom on the 4G, maybe there was a tweak in there?
Did the phone recognize the car could accept a stereo stream? I had problems once when the phone connected with the phone profile instead of the stereo streaming profile. I had to disconnect the device and re-pair the devices and that resolved my issue. I don't know why it connected via stereo stream the second time.
