No sound after installing nVidia drivers in Xubuntu 16.04 LTS

  • 772

Sound stopped working on a display port connected monitor after installing nVidia drivers for a gtx 660.

I tried restarting pulseaudio and switching between each of output devices however no sound was coming through the display port.

Searching through the forums I found some diagnostic scripts however none of them resulted in sound coming out of the speakers.

>>> aplay -l

  1. Looks like it is a known bug in the recent driver versions. See: https://devtalk.nvidia.com/default/topic/1019761/linux/no-sound-using-displayport-audio-with-375-82-384-59-and-384-69/

    Looks like we have to either wait for an update or downgrade to an older version.
