Completely disable audio jack as a media output I bought 3.5 mm. dust plug jack and I'm using its buttons, but Android is considering it as a headphone and always routing the audio to it not the phone speakers nor the Bluetooth. I need to completely disable it as a media output. Please advise or guide where to ask. Stackoverflow, Super User, XDA, Android Central or Reddit. My phone is rooted and ready for any solution.

Edit for in case the link was changed.

You need to send Lesser AudioSwitch intents and it'll switch between headphones and speaker..
