I did a dumb thing the other day: I was playing with a new Bluetooth headset on the VCR and trying to set up the sound output so I wouldn’t disturb a sleeping Barbie with some late-night A-Team viewing. To get the sound pushed through to only the headset, I opened the playback devices dialog under the sound options and disabled the HDMI out.
POOF! The device disappeared from the list!
Now, I admit that I’m not the savviest person when it comes to Windows 7 (I write a lot of these how-tos as a guide to myself–“I scour the help fora so you don’t have to!”), but this had me boggled; I could not figure out how to reactivate the device! A quick DuckDuckGo search revealed the answer, though.
In the device list, right-click the blank space in the panel and choose the “Show All Devices” option.
Whoomp, there it is.
