launch when headphones inserted

[slpeplow]

I used to get a list of applications to launch when I inserted headphones.
I no longer have that.
I've checked extensively as to where the settings option should be - settings, accessory, somewhere here, but it isn't here.

There was an OTA update to S3s recently.
Maybe this affected it, but shouldn't I still be able to turn this feature on somewhere?

Cheers

EDIT:
It's all right everyone. I found the answer, not that anyone here seemed to reply.
It's in Page Buddy. A new thing that came with the recent update that replaced a feature that was already there.
Page Buddy is in Settings -> Display -> ....
It seems to be turned off by default and now that I know what it is and what it does, I've turned it on.
Now a selection of choices is made available to me when I plug in some earphones etc..
