So basically I use many different driver updaters such as Driver Booster, Driver Easy and DriverMax, these three I prefer most of all as they provide most reliable drivers compared to the other ones I used recently which messed up with my drivers including Auslogics, TweakBit, Smart Driver Updater etc.īut only the DriverMax happen to backup all my drivers that I had installed on January, I started to restore drivers one after another while keeping my headphones paired to the PC and turned on during all that time, after third driver that I restored it automatically connected and I've heard in headphones 'Bluetooth connected', such a relieve. I was right when I was talking about the drivers. But thst codec does not work with snytning other than a bluetooth infrastructures that can accomodate it and speak the same jive.Īfter hours and hours I finally solved it and know exactly what was causing it. So its a bit better even that it would had been of it has worked on the first attempt, and thats what most atr Happy with, thst means abandoning the A2DP Codec replacing it witj the APTX as per above.

Anyways I got it to work and with HD Sound from the new ApTx codec from My conclusion is that the m3’s are very picky when it comes to drivers and while Bluetooth generally is very generic anything kind of works with something Thad works for most things. I had to go a bit outside the normal install routine but I explained that in my post above and provided links. What i finally did was to go and buy a Bluetooth dongle,disabled the orrfinal Bluetooth and installed this one, mind that it’s in Swedish but you can still see that it’s a Bluetooth dongle that has the APTX Codec enabled and that’s Bluetooth HD sound a codec the M3’s understand.
