Guys, my replacement arrived yesterday and after installing all updates sound still is amazing. I now need to send my 'broken sound' Surface back to Microsoft and I did a full format to delete all my stuff, and after the format sound is still bad.
I don't think this is a software issue and a replacement will be the only solution. I'm not saying get one now, if you are ok to wait then do so, you still have like 11 months of warranty.
how long did it take to arrive? I'm waiting on my replacement from MS too. Hope I get the same results as you!
I reported the issue on Friday, got a email saying the new Surface had been dispatched on Monday and new tablet arrived on Tuesday by UPS...
And the replacement, the sound is good?
