As the title suggests when i am on my bluetooth headphones and i unlock the screen the sound stutters. I am on B511 and i tried turning off the lockscreen sound and disabling the huawei lockscreen. Nothing helped. Please help.

Even after I disable the lockscreen sound it still happens. It seems to have something to do with the bluetooth version also for example my headphones are old and and cheap but my sony soundbar is new and probably has bluetooth 3.0 or 4.0 and it happens only 1/5 tines with the lock sound on. It still happens but its much better.

Edit: It started happening on the Soundbar after a while also...

Edit2: I don't think it happened on 4.2... It started from B510 onward.

Logcat:
From what I can see for some reason not shown in logcat the bluetooth audio just stops for no apparent reason when unlocking the device.
