[PD] [OT] Pd to play sounds simultaneously on 8 speakers with cheap computer

[Winfried Ritsch]

Just started some docu on puredata.info especially for BBB (to be updated next 
week with new mor up to date reports).

 http://puredata.info/docs/embedded/bbb/sound/

cheapest 8 channel USB sound-device I know of and working: Logilink 7.1.

Cutting the power of the USB cable, adding a filtered powersupply helps for 
the sound quality which is quite the same  as the ESI card for unsymmetrical 
DAs

Testing and feedback is appreciated.
