i have receiver, connected to sound output of my iMac MB950LL/A.

I cannot switch sound to iMac's internal speakers without unplugging the cable from it.

Can it ever be done without touching the cable ?

Yes, see the Output panel in the System Preferences > Sound preference pane.

Apologies, I did some searching and that iMac model may have the sound output on a hard switch. Annoying. Look for an application called "Audio MIDI Setup" in the Application:Utilities folder and see if that works.

If not, another solution would be to get a USB sound interface, like a Griffin iMic. Some googling may find a more inexpensive interface. Like maybe this one.

No. I cannot do it, because i see only ONE item in the outputs list: "Internal output", while cable is unplugged; and "External output", while cable is plugged in. – AntonAL Jun 29 '10 at 9:22

The free app Soundsource puts audio input/output switching on your menu bar.

It does not work for me. It shows only one output. – AntonAL Jun 29 '10 at 9:24
