I just discovered that an Application of mine which records input from the
microphone port has broken on the new G3's. Basically what happens is that
the recording level is way too low.

It appears from TechNote 1124, that a program that records sound needs to
set such things the recording gain, input device etc as of OS 8.1.

Does anyone know how to do this? I cant find the relevant calls. I'm also a
little confused as to whether this should be done via QuickTime or the
Sound manager. At the moment all I need is to turn up the gain, I can add a
user interface latter.

Any help would be appreciated.


PS I looked for the relevant code in FB^3 in Quicktime.Incl and Sub
Sound.Incl but none of the necessary functions to display/change recording
settings seem to be built in to FB^3! (eg the recommended SGSettingsDialog).
