So "multi" does work fine on an SMP system. The timing problems are only introduced when "multi" is combined with "dmix" for 5.1 channels. I would like to help out in fixing this, but need a little bit of guidance from the experts here. Have I identified the problem correctly? Ie interaction between "multi" and "dmix" on a 5.1 channel card giving timing issues on an SMP system? If it is unlikely, I will investigate other areas.
