I have an S-Off and rooted HTC One and have recently got AKG K451 headphones. The middle button works for pause and next track etc but unfortunatly the volume up and down does not. Is there an app or anything I can use to force the up and down volume to work?
I have done a search but all the threads I have come across are no longer pliable.
I assume your K451 has 3.5mm connector on earcup, so that cable above will work well. As I mentioned in some of my previous posts, multifunction button is universal and works for play/pause/call, double click to skip and long-press for Google play, but volume controls are usually for iDevices only. There is no way to fix it with an app or rooting. Its a hardwired thing (internal resistors inside of the remote). This replacement cable above has a remote specific to Android phones, works great with my Note 2.
