Ubuntu 16

My configuration:

Ubuntu 16.04 LTS
Nvidia Quadro K1000M
Nvidia driver 418

I want to connect my laptop to TV, but the laptop has only a display port so I have bought hdmi to display port adapter which supports audio and video transfer. A video transfer works fine but I can't play sound from the TV speakers. System settings / Sound doesn't contain any option besides Speakers (Built-in Audo). Even when I disable a laptop screen sound is still played from the laptop speakers. How to fix that ?

Try this.. go to Settings>Sound what is in the output? Should see HDMI/DisplayPort or something like that.. can you give a screenshot? Also run the command lspci to get an idea of your hardware.. perhaps a module not installed or not built in kernel.

To set sound output to the HDMI port:

Code:

pactl set-card-profile 0 output:hdmi-stereo

To switch it back:

Code:

pactl set-card-profile 0 output:analog-stereo

Once the above has been done at least once, you can use the GUI pavucontrol->configuration: Digital Stereo (HDMI) Output & Analogue Stereo Output to switch between the two.
