Well, the driver will let you do the setting you want, even if it's wrong :) You should indeed keep PCM at about 75% and use the master. There is also an issue with bad quality speakers used by Apple. OS X has a built-in software DSP that does equalisation & filtering in the kernel driver, and they have specific settings for it for various machine model speakers. Obviously, we don't have such thing. Ben. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
