Overly long sound card descriptions is a problem and they sometimes cause problems for some GUIs as pavucontrol where you need to make the window very wide in order to accommodate the strings. With pulseaudio you can rename them directly in pavucontrol by right-clicking the Port dropdown as long as you have the module-device-manager pulseaudio module loaded. Here is how to do the same in pipewire:

Add something like the following to your `/etc/pipewire/media-session.d/alsa-monitor.conf/ file:

    {
        matches = [
            {
                node.name = "alsa_output.pci-0000_02_02.0.analog-stereo"
            }
