Audio Switch

Just click on the volume control with "alt", then you should be able to choose the speakers you want.

(No additional speakers pluged in on my macbook right now)

 

On my iMac that does not work, i.c.: it shows the picture as above,
but nothing you can change with any key I tried or any mouse click.
When I connect headphones the picture simply changes to "headphones".
;JOOP!

 

Just checked it with my earphones on my macbook, same result. On my iMac i have a headset with a external soundcard. I guess thats the reason why i can choose it on my iMac and not on my Macbook with the earphones connected.

I guess you can only choose the output of the soundcard then. If it is true, it should really be fixed. Really annoying to pull out the headset for speaker. But maybe there is an app for this?

Quick search, bit old but maybe useful?: https://discussions.apple.com/thread/2609977?start=15&tstart=0
