sound control

[kiwi]

Applications/utilities/audio midi setup

but you should be able to look at the sound inputs in the system preferences in the sound inputs tab

You can then enable audio input into catalyst in the inputs widow in the HUD.
Catalyst picks up the audio channels that are made available to it by OSX. the controls for the sound inputs are done by the OS, there are no controls in catalyst just meters in the inputs window.

hope that helps

Literally Catalyst uses the audio interfaces it sees with Core Audio, which differs with different interfaces.
