Folks, following situation: * A notebook with working loudspeakers but failing headphones ? as soon as the headphones are plugged in, there is no sound. This is most likely a hardware problem since it happens with Windows also. * A small USB audio adapter which is properly recognized by openSuSE (this is, by ALSA). I now want to have this behaviour (which is independent on the hardware failure; I believe that such a behaviour would be beneficial in general): * As soon as I plug in the USB audio adapter, the whole system should use it instead of the built-in sound system. Of course, as soon as a remove it, the built-in sound system should be used again. I was told that PulseAudio might be a solution (I've never tried it yet). How can I do this? Werner
