I never had time to write up a proper report on this, but when I was trying to get sound going on my notebook PC, I found that when (at first) I had the two DMA channels reversed in my config file (since I didn't know which was which in Luigi's driver) my machine locked solid when I tried to play a sound file. Reversing the DMA's fixed the problem. Did something change in -current (which I don't follow) to change the way DMA channels are interpreted? BTW - when using the standard (Voxware) driver, I found that having the DMA channels "backwards" just resulted in a diagnostic error message about a possible conig error, but not a lockup. Could you perhaps detect this situation, Luigi? When I get some more time I'll write up some more on my notebook sound problems - but thanks, Luigi, for your efforts so far...
