In practice, it depends on the driver and also if the two cards are configurable at different addresses -- and quite a few cheap PnP boards do not have a unique serial number making them undistinguishable :( In the specific case, my driver (device pcm0) supports multiple boards of the same type for all cards it knows, so you might be able to achieve what you need using the OPTI in 16-bit mode (WSS clone) and maybe the PAS in SB emulation (but i am not sure my driver will recognize the PAS -- i have not been very careful in supporting obsolete hardware). Personally i have run up to 3 boards in my machine. Voxware driver has some restrictions with multiple devices. > looking to pick up the extra dsp and mixer.

A CLONE might have a proprietary 16-bit mode of operation known to windows and in this mode (not in SBPro emulation) it does 16bit. 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/ _____________________________|______________________________________ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
