miui v1.8.19 - music stops playing after phone unlock


Aug 25, 2011
After listening to music for a while, I'd unlock the screen and the music would stop playing. I click play again but I get no audio. Then I try to reboot the phone and the reboot and shut down toggles in the notification bar stop working, I need to pull the battery. This happens every time. I am unsure why the music problem is linked with the power controls. Does anybody else have this problem?
