2.$ xrandr --verbose
3.$ xrandr --output DP1 --crtc 2

Expected Result
After step 4, should play audio normally.
Actual Result
After step 4,the audio sound is abnormally.
Comment
The bug happens randomly and can be reproduced only on DELL U3011. What's more, we found after running the command `xrandr --output DP1 --crtc 2`, the display will be abnormal on the monitor DELL U3011. It seems there is offset to display the desktop.
