I’m unable to get the audio speakers on my external monitor to work over HDMI with Fedora Linux 43. Gnome control center shows the device, however I do not hear any sound. Is this a configuration issue or am I missing the proper drivers?

Gnome 49. Kernel 6.17.7

Have you installed the nvidia drivers from rpmfusion?
If not the nouveau driver is being used and is probably the problem.

Installing the nvidia drivers did solve the problem.
