How to stop detection of HDMI speaker?

Hi all.

I have an HDMI external monitor, connected to a USB-C hub. It has a horrible speaker. Sometimes when i plug the USB-C hub, the display speaker is recognized and it starts being the default output. It even goes as far as unmuting itself (because it's muted in the KDE sound applet).

Is there a way to exclude this speaker? Actually in pavucontrol there seems to be unplugged entries for all possible video outputs which may have sound, and i'd like them to be permanently set to off at all time, and never hijack the sound output.

Thanks.

If you're using pipewire/wireplumber https://wiki.archlinux.org/title/WirePl … evice/node if you're using pulseaudio you can sticky the selected hdmi/usb card profile to "off": https://www.freedesktop.org/wiki/Softwa … ettosticky
