No DispalyPort option in audio output device menu, Nvidia Drivers

by Syndelis   Last Updated August 14, 2019 01:02 AM

I can't get my DisplayPort-connected monitor (AW2518HF, external speakers connected) to show up on this drop-down menu: Settings > Sound > Output > Output Device.

I've opened Nvidia X Server Settings and can assure that DP Audio is enabled. Additionally, I booted Windows 7 and was able to select it and play sound just fine.

I'm using a GTX 750 (EVGA; they added a DP port in their version) with the 418 driver installed from Software & Updates on Ubuntu 19.04.

Here's aplay -l
