iChat 5.0.3 How do I mute incoming audio?

[nuform]

IChat is great, not too hard on the cpu/gpu and doesn't heat up my 2011 MBP '13 as much as Skype would; but how do I mute the incoming audio of the person I am chatting with. Anyone know a solution to this? or is this not possible? I doubt Apple would something so simple out. Please and thanks.

No that would mute me, the outgoing audio. I am trying to figure out how mute the incoming audio, the audio coming from the person talking to me. I want to mute them because at times we watch movies or do homework so I do not need the audio coming in. I do not want to hear the background noise such as: fans, keyboard, tv's, etc.
