Can somebody point me to a link, or explain how the sound is supposed to work. On my last system, there always appeared to be a contest between Firefox (e.g. after YouTube) and other applications. Sorry for being so dumb on this, but I am a software developer and rarely tried running sound before. In my home I have a receiver that allows me to chose the desired input channel. How is this accomplished under linux? It also is not clear to me which software components need to be loaded. I saw on the online setup how to make the system bark, but not how to select between Firefox and Rhythmbox, for instance. I also installed the Rhythmbox RPM and cannot make it operate. It will not load my large directory of music file. If I select a single track, it appears to be playing the track (as the bar moves across the top) but no sound comes from the speakers. I did a Google on opensuse 3.2 sound and most of the listings were ancient, like 2001.
