I'd say it looks kind > of promising; but I'm not too keen on yet another audio system... I don't have a precise position. On one hand, it is nice to have all audio cards under the same device driver, because it makes life easier for the user. On the other hand, differences between cards can be large so it might be more effort to merge a new card than to write a brand new driver. E.g. some russian hacker sent me a standalone driver for the ESS cards which probably has infinitely better support for those cards than my driver. Because of the differences between PCI and isa, i think that if you feel like writing a standalone driver for the Ensoniq, go for it. Whether it is simpler or harder than integrating this into the "pcm" driver, i cannot say, it all depends on how much code can you adapt (i have seen some PCI audio card data sheets that show partial emulation of ISA cards on the PCI bus, but i am not sure if they allow e.g. full duplex). 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
