SubjectRe: Support for YMF724 soundcards?
I, too, have looked into writing a driver for this chip family.  As mentioned,
the PDF documentation online is unreadable, and I have contacted Yamaha about
reciveing a hardcopy.
I was unable to get my card operational with the oplsa2 driver, though I will
have more time this weekend to play with it.
