You might try if you get success with my ad1816 patches for Luigi's code. They are located at http://www.mayn.franken.de/users/tanis You will at least have to add the PNP id of your card to the pnp probe. If it works you should get better support for your card than with just Soundblaster emulation. -- German Tischler tanis@gaspode.franken.de Apple eaten (core dumped) tanis@cip.informatik.uni-wuerzburg.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
