Looks like PulseAudio is not running. When I try to start it I get this:
[root at localhost ~]# pulseaudio

So this means that I'm nog going to be able to play audio on the  
LineOut1, LineOut2 and HP at the same time?

How can I use the mixer controls? Do I need some specific devices?

Sorry for my questions but I'm missing some items to complete my audio
