In many cards, the microphone connector will be pink, the line out or headphone will be lime green, and the stereo line in will be light blue.


I've not tried it, but if you're willing to spend the money, that may allow you to connect a pair of headphones with a normal 3.5mm jack then, using the method above, get audio out of both the internal speakers and the headphones simultaneously.You might be interested: Readers ask: How To Play Popular Song On Piano? What is the Blue audio jack for? IMic supports both mic and line level inputs via a selectable switch,Īnd provides a line-level output for connecting speakers or However, whilst all this may be largely academic without a USB headset or speakers, I did also come across the Griffin iMic which says: So be careful with those headset and speaker levels to begin with!!!Īnd that's it :) So, now when you play a song in iTunes, for instance, that should come out of both the headset and the speakers. To do this, you'll have to go back to Audio MIDI Setup and do it from there for each of the outputs. Select the "Multi-Output Device" that's now there.Īn unfortunate side-effect of this, as "The selected device has no output controls" eludes to, is that you now can't control the volume in the normal manner. Start "System Preferences" → "Sound" and click the "Output" tab. Select the Multi-Output Device that has been added and in the right-hand pane, select both the "Built-in Output" and your USB device. Select the "+" in the bottom-left and select "Create Multi-Output Device"

Start the Apple "Audio MIDI Setup" utility ( /Applications/Utilities/Audio MIDI Setup).In order to get this to work, you'll need to plug in the USB device, then do the following: Now this may not answer specifically what you're asking, but for interest, the only time I've had any success with simultaneous headphone and speaker output is when using a USB device, such as a headset or USB speakers. There are several discussions around as to whether this is actually a limitation in the hardware or the software, but the end result always seems to be the same. As soon as you plug in the headphones into the 3.5mm jack, it replaces the internal speakers as the default output (and vice versa when you unplug them).
