When my Surface RT is in standby with cover closed and notification comes up, sometime sound plays but the speakers are distorted and the noise crackles. The audio is just stuttering. However, I listen to music and play games and the speakers work just fine without blown. My friend also have the same issues. After the tablet is in sleep or standby mode, the audio is crackly sometimes. Try making Windows updates/drivers can’t fix the issues.

* Tap on Change when the computer sleeps.
