I have a vaio F-650 which also uses a Yamaha chipset, although not the exact
same one...lspci says: 
Yamaha Corporation YMF-744B [DS-1S Audio Controller] (rev 02)

I managed to get mine working by compiling the OSS sound modules (soundcore,
IIRC) and selecting "YMFPCI" in the kernel configs.  I don't load them as
modules, however - I built mine directly into the kernel (so YMMV).  Here's
what I get in dmesg:

ymfpci0: YMF744 at 0xfedf8000 IRQ 9
ac97_codec: AC97 Audio codec, vendor id1: 0x414b, id2: 0x4d02 (Unknown)
Sound initialization started
Sound initialization complete

It seems to play wav/mp3's just fine.  I do have problems with the Flash
plugin under Netscape, however (the sound is _really_ choppy).  I haven't
found a fix for that yet (mainly because I don't visit that many
flash-required sites ;P )

Hopefully this will help, or at least point you in the right direction.  One
of these days I'll get around to trying ALSA out =)
