Hi
I ended up taking back the 2nd surface 3 for a SP3. I tried what you said....it didn't work. I took the first 2 back because both had the same problems. The audio would work on/off.....the volume rocker would not go up or down, when released it drop or increase
by 10 whichever way you were pressing. As well as the keyboard issues. I don't know why they released this... it certainly wasn't ready for release. This one wouldn't keep my micro sd info in the drive.... you would be listening to it... it would stop and
all songs would disappear from WMP....I would look in the library, sure enough that drive (D) had dropped. The card isn't corrupt.... you could play it from the USB drive. I had another new one... opened that and no problem. I think the lock screen is the
problem with this. I use WMP because the equalizer works with my Bluetooth speakers. In the WMP player tab settings the box you check to keep the music playing with the screen off states to allow playback while screensaver is off. We don't have the screensaver
anymore.... if I set my screen to go off in 1 minute... it does but that is when the playback stops as well, even though I check the box for it to never go to sleep. There is a way to go in and disable the lock screen. I saw that on you tube, but haven't tried
it yet. I'm glad it's even playing music and not disappearing, but feel they have charged way too much for something not ready for prime time. Samsung has it down pat as far as the music players..... in fact they make great tablets, I've had a few. I wanted
windows tho. Good Luck....nt
