Yup, it works.
However, I can not do this everytime when this problem appear, because everytime i put my computer sleep. this problem appear.
I made a appoiment with Apple Store, I hope they can fix it, Do you guys think this is the MAC's problem (no enough power for USB port) or Display problem?
What i find is , the sound come from USB in thunderbolt. It also show as USB in OUTPUT, Therefore, i think the issus come from the "NO ENOUGH POWER FOR USBs in Display"
