The sound is not loud enough. Simple as that. It is not even half as loud as the original Surface. YouTube videos are barely audible even at full volume. I never use headphones.
Could you check the sound driver version and if you have the sound enhancements enabled?
I do not have this issue.
Thanks. My driver version is 9.17.13.2774, dated 11/26/2013. I'm wondering if I try to return it under warranty. But from what I have read, people seem to still have the problem on the replacement device as well. I'm losing optimism that a driver fix is coming.
Did you check the enhancements check box? It should be enabled.
