Of coz having touch sound + screen lock sound will use up some battery of yours. But it's not the continuous battery draining wakelock (draining even when you're not using the phone/screen off).  It only drains when sounds are played.  If you wanna eliminate Audio_Out1, mute your phone TOTALLY   Every time you touch the screen, a sound is played, for sure some battery will be taken
