Depending on the driver and the card you can install multiple audio cards on the same machine, but beware: - some cheap PnP cards have the same PnP id, so there can only be one of each kind on the same machine; - you might run out of DMA and interrupts very soon; - there might be drifts in the clock speeds of different cards so you might end up with recordings of different length for which you'd need to compensate the drift. cheers luigi -----------------------------+-------------------------------------- Luigi Rizzo | Dip. di Ingegneria dell'Informazione email: luigi@iet.unipi.it | Universita' di Pisa tel: +39-50-568533 | via Diotisalvi 2, 56126 PISA (Italy) fax: +39-50-568522 | http://www.iet.unipi.it/~luigi/ _____________________________|______________________________________
