i made an error. <<if i set webcam to "default alternative" and i restart pc then webcam is no more "default alternative">> is false
Can you attach the output from "pactl list"?
Created attachment 128759 [details] pactl list log
If I understood correctly, the problem there are two sources, the internal sound card and the webcam, and pulseaudio decides to use the internal sound card, even though it has no microphone actually attached to it. "pactl list" shows that all ports of the internal sound card source are unavailable, so PulseAudio knows that the internal sound card is unusable, but still does the stupid decision. I believe this is caused by module-device-manager, which KDE uses to manage the device priorities. It doesn't currently understand ports at all, which means that it doesn't check whether the currently active port of a source is unavailable before deciding to use the source. Thanks for the report, I hope this will get fixed. I can't promise any timeline for that, however.
I have one thing to add: I assume that by "default alternative" you mean the default source. There's always one source designated as the default source, which you can see in pavucontrol. I have submitted patches that improve the default sink and source handling, and if they get accepted, I think the webcam will be automatically chosen as the default source. However, I believe that won't really help you, because when module-device-manager does its routing, it doesn't care about the default source, because it has its own priority list of sources.
hello thanks for all i add a bug report also to bugs.kde.org about phonon. https://bugs.kde.org/show_bug.cgi?id=374460 i am going to complete it with your data about module-device-manager
solved with pa 11
