I have my S2716DG connected via DisplayPort and have a pair of Bose powered speakers connected to the Line-out port on the rear of the S2716DG. Things have worked well till today when I came home and I have no sound from the Line-out. I can swap the wire to the side Headphone-out port and things work, but my S2716DG sits at an area that I cant have anything on that side. Is there some type of toggle that would turn that port on or off? I don't see any errors in Windows Device Manager. The S2716DG is set as my default audio output device.
Windows 10 64 GTX 1080 Ti DP out port --> DP to DP cable --> S2716DG DP in port
I've installed/reinstalled video card drivers. Looked for any audio driver updates, uninstalled/reinstalled video/ audio drivers.
I've tried using older versions of video card drivers hoping it was a Nvidia error. Still same issue.
* Turn the out of warranty S2716DG off * Disconnect every cable (including the power cable) from the rear and side of the S2716DG * Press the S2716DG power button in for 8 seconds * Reconnect the power cable, single video cable, and the speakers to the S2716DG and retest
