Ah well, you can use it on your PC if you swing that way. Should be cool, you can route audio to the internal speaker of the Dualsense from the audio control panel in windows, this also triggers the haptic feedback to "play" along with the audio that comes out of the speaker. So you can mute the internal speaker but you still get the haptic feedback that is generated from the audio that is routed into the speaker.
Would be kinda crazy with pounding music haha. If only you could route only the sound effects to the haptics it would be amazing. You could do that I guess but you'd need to mute all the other sounds in the game, music, dialogue, etc.
