So having got the sound to work on my Acer Aspire 8920 there was one small annoyance left and that is that I can only use one sound application at the time. It does not sound as a very bad thing, but its annoying. Like when i playing my game and someone sends me a msn message, kde tries to sound a audible warning or notification and I cant here then – all will pop up when the game closes down.
When reading about pulseaudio it seems to promise to solve all the problems, multiple applications and even individual volume controls for each application, so it seems promising. The only problem is that kde is not handling pulseaudio direct so there might be some work necessary to get the kde notifications going.
First thing ofcuase was to get the sound to work at all. Without ALSA working i dont think this would have succeeded at all. I did found 2 notes/links to information about how to do this so i followed that and added some things of my own.
