Yes, the Mac Portable, Mac SE/30, and all the Mac II machines use the ASC
(Apple Sound Chip) and two Sony sound chips (analog/amplifiers).

For more detailed info on the sound circuitry, check out the "Macintosh Family
Hardware Reference" published by Adison-Wesley.  If you want to program with
sound, though, I'd suggest getting a hold of the soundmanager documentation.
It's available for anonymous ftp on apple.com, in the directory
pub/dts/mac/docs/soundmgr.hqx.  While you're there, you might want to get
tech note 168 (on playing sounds in hypercard) in
pub/dts/mac/tn/tn.151.200/tn-168.hqx.
