Hi, if I plug in an USB audio adapter, I want sound for all applications to be switched from internal speakers to the USB adapter, automatically. And if I remove the adapter, back to internal speakers. what is the recommended way of doing this? I noticed that pavucontrol does not see new connected USB devices, not even after restarting it. I have to do (kubuntu 12.04, pulseaudio 1.1) service pulseaudio reload first, but this not only reloads configuration, it actually does a restart, killing pulseaudio. So my application (vdr-sxfe) loses sound, and I have to restart it too. removing the USB audio adapter works, sort of. The sound is switched elsewhere. But there is my 2nd problem: My notebook has a graphics adapter with HDMI output. I want to disable this forever. But if I do that in pavucontrol or in the KDE sound mixer, this only holds for some time, the device always comes back and is preferrably used by pulseaudio. when I disable sound profiles in pavucontrol and reload/restart pulseaudio, they are enabled again. So how can I permanently disable a specific audio sink? -- Wolfgang
