How about SetSoundVol((int) Volume); ? I see no wrong in this easy-to-use,
well-documented Toolbox call. Sometimes you get too technical to see the
obvious :-) (Oh, by the way: You shouldn't change the volume in PRAM, since
this is a) considered a brach of the HIGL and you risk the wrath of the
HITP (Human Interface Thought Police) and b) subject to change without
notice (well, almost :-)) The user can do this through the Control Panel
if he wants to do it.

Unless you're writing a "General" cdev substitute, of course...

Happy Hacking !

(Oh, by the way, SetSoundVol is on page 233 of IM-II, and there's even no
TechNote about it, so I think it's still valid, all according to my XRef)
