HDMI output on TV doesn't work

Hello, am new to Linux, everything worked fine when i installed Zorin Os on my laptop but when i plug it using HDMI to the TV the sound doesn't work I fiddled around with the output configurations on the sound setting and on the pulse audio volume control and made sure that i was outputing to the tv but still no audio, the laptop speakers works fine and also the headphones (wired and wireless), i also changed the ports and used other hdmi cables but still no success, if anyone here had the same…

Original Post:

Just installed Zorin 17 Core as a replacement for Windows. Things have been pretty smooth except that I don't get audio output over HDMI.

I installed PulseAudio Volume Control based on another thread, and it works! I get Digital Stereo Output over HDMI. But as soon as I close the PulseAudio Volume Control application, I no longer get any audio output.

Is there a way to figure out what configuration change the application is making and make that permanent?

Other things I've tried.

• apply all updates
• disable all other audio output sources except for GP104 (an Nvidia 1070 graphics card)
• switch from X.Org Nouveau driver to Nvidia-driver-570.

The only thing that works is having PulseAudio Volume Control (installed through store) open.
