I am wondering if something broke in a lower level component there. It definitely should show 'Dummy Output' and since the tooltip shows it the text is probably set correctly but not showing up.

I'm having the exact same issue has well, I've tried everything, LSPCI is the only thing currently showing my audio device

Operating System: Arch Linux 
KDE Plasma Version: 6.2.0
KDE Frameworks Version: 6.6.0
Qt Version: 6.8.0
Kernel Version: 6.11.2-arch1-1 (64-bit)
Graphics Platform: Wayland

Memory: 16.7 GB of RAM
Graphics Processor: AMD Radeon RX 6600

System Version: 1.0

I would expect this broke at a level below us, yeah.

        // Don't ever show the dummy output, that's silly
        const dummyOutputName = "auto_null"
        if (sourceModel.data(idx, sourceModel.KItemModels.KRoleNames.role("Name")) === dummyOutputName) {
            return false;
        }

:D

*sigh*

I think I found the problem. Dummy output has no ports and we have code that assumes there's a port.

fix text display for auto_null device

the device has no port so the currentPort text choice ended in nothing
but a warning. instead fall back to the default button text, the same
source used for the tooltip
