Thunderbolt Cable
I have my 11-inch Thunderbolt MacBook Air connected to my 27-inch Thunderbolt iMac with an Apple Thunderbolt cable.
When I type Command-F2 on the iMac to switch the display to the MacBook Air, the sound on my iMac is muted, but when I toggle back the display to the iMac the iMac sound remains muted.
The automatic muting makes sense, but shouldn't the iMac sound setting be restored when I switch back to the iMac?
