I am having issues with the audio output while running Ubuntu 16.04 LTS on my HP Omen laptop.
I had to install the latest Nvidia driver for the HDMI video output to work but still there is no sound. I have looked through Pulse and tried to modify the configuration to HDMI, however all outputs say that they are unplugged. It also does not come up in the Sound Settings and when I list devices in the terminal ,it says that HDMI output is not available. I am also unable to see Bluetooth audio devices in Pulse when they're connected (unsure if this is related).
How do I resolve this issue ?
