Christoph, Here at home I have a Creative Audigy which one I guess have hardwaremixing capability but at my job I have a nForce2 based onboard soundcard which one I'm not sure if have hardwaremixing. I did a test killing all process of esd and arts and trying to play more than one instance of music playing and that's works very well with Audigy but don't with nForce2 onboard audio. An other thing that I've noticed is that skype just work without arts or esd, so I've to run "skype oss" to be able to use it (at my home machine, since I don't use skype at job yet). I think that at home I do not need any of this daemons but at my job I will give dmix a try, so I have to ask you if even with dmix I'll need to use arts and/or esd? Tks in advice.
