[PD] Linux: changing sound card params from patch, sending OS commands

[John Harrison]

I'm using Pd as part of the engine for an interactive art project. The 
setup is an old PII laptop running xubuntu Dapper. I'm stuck on a few 
things:

   1. It's a long story but the bottom line is that it appears that I
      have to use this crappy computer as well as its less-than-steller
      internal sound card, and that the internal sound card or driver
      has some sort of bug which requires me to switch to ALSA *after*
      starting Pd. Everything else produces no sound. And OSS is
      completely inoperative. So is there a way I can do this in a
      patch? (The sound card is a Yamaha OPL3-SA23 BTW.)
   2. I'd like Pd to be able to send commands to the OS such as shutdown
      -h "now" when the gallery closes each evening. Is there a way to
      send such commands from a patch? The only thing I could think to
      do is send a message to a Python script using sockets....seems
      rather clumsy.

Thanks,

-John
