Any ideas on this? I have a Sony MDR XB950bt pair of headphones which only connects over A2DP (I checked in logcat) to my Galaxy S3. The headset should support apt-x according to their webpage: http://store.sony.com/extra-bass-bl...XB950BT/B/cat-27-catid-All-Headphones-Earbuds I should be running Samsung's stock ROM, so I'm not sure what else would effect it? Some hidden setting maybe? Thanks!
