13" MacBook Pro not detecting output device

[tystakes]

When I put a mini-stereo plug in the combination audio jack, my late 2009 13" MBP does not automatically detect the device and use the device as an analog output device. The speakers/headphones/whatever do not show up in preferences. This is a very frustrating issue. Any fixes/ideas? Is this a hardware issue? Thanks.

The combo jack should automatically switch to output upon detecting headphones, speakers, etc. It's possible there may be something wrong mechanically with the jack, but it's more than likely a logic problem if it won't switch over.

Your machine is still under warranty. You should have somewhere in Singapore where you can take the machine and have warranty work done. Either an Apple store or an authorized Apple repair service. Take it on in.

I've got the same mac and unfortunately the same problem. But in my case i have to put the mac in stand-by after i insert my headphones, then switch it on again to get the mac to detect the device. And even sometimes it changes automatically w/o doing this procedure (like it should), but this is seldom. Got some advice to get rid of this issue without shipping my mac for repairs?

Sorry no. The combo jack has been problematic for some folks but the only way to resolve it is to get it repaired. Like the other user, if your machine is under warranty, let Apple deal with it.
