No sound on external monitor

I been trying to get sound working on my external monitor with success. I am running leap 15.6 and modifications i did to it was to install nvidia drivers from the repo.

The laptop and the external monitor are connected using an hdmi cable.

Not sure if this matters but I also have secureboot active. I created my own keys and signed the nvidia drivers and everything seems to work…

I also installed pipewire pipewire-jack and pipewire-alsa.

When I select the radeon card no sound when I switch the sound comes out of the laptop.

Here is some info:

one more thing, too make sure that the external monitor is nit faulty I booted a live usb iso and sound works on external monitor…

Is this a driver/kernel issue ?

I made i typo in the beginning. the sound does NOT work on external monitor

Please post commands and output as pre-formatted text. It is much easier to read and preserves the layout of the output as it was captured.

Please show us the results from
pactl list cards

If you have ‘pavucontrol’ installed, you can run this utility and check/adjust the desired profile.

is this rpm required suse-prime ?
