I have access to a few low-end sound cards, and I had little luck with them under FreeBSD (but then I only wanted to play with ISA PnP, and at little more than $15, I didn't those cards to actually work :) > It'd be a nice feature for the existing user base too, if it isn't > technically impractical. There once was a posting that indicated patches to cards based on the Opti chips, which fixed the probe and made them work more smoothly. I once had one of my cards running well enough (worked great with raplayer, until I made it run under rtprio to listen to some radio program during a large compile and had the system lock up solid :), but after building a kernel without sound support, I never succeeded in driving that sound card anymore :( I really think we should try to fix the current sound drivers, no matter hwo antiquated they are. We loose customers, else, and I for one, would also prefer to play with multimedia tools ... Regards, STefan
