Hi,
As it has been so long I reread the topic.
I am now confused though.
In the first post you said
... It works fine with Skype, but when using iChat, there is no microphone pick up. I have set the audio settings to the USB headset in both the System preferences for my iMac and for the iChat preferences; ...
From that I went on to say set the iChat bits to anything else then set System Preferences > Sound > Input and then reset iChat to the Headset Mic option.
You then said it was the Output (incoming Audio) that you could not hear.
I suggested the same technique be applied to the iChat Output options/System Preferences > Sound > Output with iChat again being Set "Last".
You have replied that you have set the preferences in both places but not to the order in which you did them (this is the important bit).
I have seen one post that suggests that Output to the Headset should be done before the Mic/Input settings but did view this with a deal of scepticism.
Also even though you have no MIDI device can you Open Audio MIDI Set up in Applications/Utilities and see what sample rate the Headset is using for Input (Mic) and Output.
Ideally iChat seems to prefer 44100
You may also notice here that you have different controls over the volume.
Is it Mic/Input (your Outgoing Audio) or Incoming Audio/Output to Headset that is the issue ?
