No sound from Samsung Chromebook 3

[DonaldsRump]

I have no sound coming out of my Chromebook, either from the speakers or the headphone jack. I've done everything I can think of including a hard reset, PowerWash etc, and still no joy.

It's still under warranty, so hopefully I'm ok there, but does anyone have any thoughts? When I move the sound/volume slider bar, it's constantly on mute. I can move it to any volume, but when I go back to it, it's back on mute again. The volume icon, interestingly, just shows the speaker and no lines emanating from it at any volume.

Have never seen this on a Chromebook, PC, or Mac. Have called Samsung, and they say send it back to them. I'm just trying to see if there's anything left that I can still try before I mail it off for repairs.

Thank you!
