I just got my Surface replaced and while setting it up the sound volume suddenly dropped off, which used to happen with my original Surface. The first time it happened on my old Surface I thought it was Pandora. I contacted them and they said no, they were not having a problem. Eventually, the volume returned, it always did; on my original Surface, but why is this happening again, on a brand new machine. Just like it did on the old one? I checked and it's low to the external speakers attached to my docking station, it's low on the speakers on my external monitor and it's low on my Surface speakers, so it's not the hardware. And since it's a brand new Surface, and it's happening, again, the same way as it did on my old Surface, it seems safe to say that it's a Surface issue. Does this happen to anyone else.
