I just purchased two new Surface 2's and I am noticing a significant reduction in volume from the speakers compared to my old Surface RT. The speakers also lack any kind of bass. They are very "tinny" and shallow sounding. When using headphones, there is plenty of bass sound and the volume level is not an issue.
I am also experienceing a significant amount of sound crackling (from the speakers and attached headphones) when streaming video from Amazon Instant Video using both the desktop and metro versions of IE. I do not experience this crackling problem with other sound sources like Xbox music, gaming, or other website streaming video (i.e. YouTube).
Since I was experiencing this on two different Surface 2's, it seems unlikely that this is a hardware issue. This is most likely a software/driver issue. Is there anything that I can do to resolve this problem, other than wait for a possible software or firmware update?
