Bug 422733

I have periodically experienced this but am not currently able to. :/

This is the same issue as Bug 422612, which will be fixed with https://invent.kde.org/plasma/plasma-pa/-/merge_requests/5.

Are you sure? This bug is not about non-available additional devices (like the bug you linked), but about the radioboxes. All devices in the attachment are available (there are the speakers and the speakers of the dock, so different devices, which are all available)

All right, maybe not then.

And this is happening for you in Plasma 5.19?

Can you run plasmashell on the command line (`plasmashell --replace`) and see if there are any errors printer when you click on one of the radio buttons that doesn't do anything?

Ok, I was able to reproduce it again. To reproduce do the following:

1. Plugin headphones.
2. In the sound KCM, configure to use the speaker port, not the headphones. (Note, maybe it is a result/combination of this https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/917)
3. In the applet or kcm first choose the speaker device, then any other output, this may be a bluetooth speaker or something else.
4. See, that both radio boxes are enabled.

However there wasn't an error output at the correct moment, but here is the output anyway:

qrc:/plasma/plasmoids/org.kde.plasma.volume/contents/ui/main.qml:580:39: QML DeviceListItem: Binding loop detected for property "width"

Still happens to me with 5.20, with the steps given to reproduce above in #5.

I think the underlying issue is that pulseaudio/plasma-pa doesn't go back from the headphones port to the speaker port if the headphones are disconnected. All pulseaudio configuration is unchanged and the default as delivered by the Arch package.

I haven't been able to reproduce this in a while. If you're right though, that would make this mostly a PulseAudio bug.

I'm going to close this until I know that it is indeed a plasma-pa bug. Though, plasma-pa could handle and resolve the issue too, but that's probably not a nice solution.

Ok, quick update: the buggy radioboxes are gone with 5.21. Only switching away from headphones and playing on speakers with headphones plugged in doesn't work, but that's a pulseaudio bug now for sure.

With Pipewire the switching works perfectly, in case anyone finds this thread in the future and has the same issue.
