Hello there,
I have been featsing on the wealth of information that exists on this topic. Despite all that info, I have only managed to get rid of "Dummy Output" in my sound settings to "HDMI/Display POrt - Built-in Audio" but still no sound.
Some helpful outputs from some commands:
E: [pulseaudio] pid.c: Daemon already running.
E: [pulseaudio] main.c: pa_pid_file_create() failed.
Code:
