[REQ] Headphone mode switcher

Hey everybody,
I was wondering if somebody knew of an app that could force the desire to output the sound through the 3.5mm jack or could write one (doesn't have to look fancy)
I found toggleheadset2 but that doesn't work for android 2.2, also found sound route switcher but has the same problem.
So can anybody please help, because my phone has problems recognizing my headphones (some waterdamage) and heading on a trip in two weeks and I don't want to annoy everybody on the plane with the sound of the movies i want to watch on my phone.
Thanks in advance and hope I was clear

Has nobody any idea?

Do you just need to "reconnect" the device or do you need to "pair" it again?
No idea about your other questions, some of them I don't understand (sorry).
You can also try the rom by booroondook which is the one I am using. Working very well for me.

USB sound card with ATOTO A6Y2721PRB

Hello everyone,
I really need your help. I bought a ATOTO A6 PRO (A6Y2721PRB) to use it with a usb external sound card (PCM2704 chipset).
It works well with my Android 5.1 cheap tablet but no sound when I try the exact same thing ont the headunit. I tried Neutron app with USB direct mode and it works well but I want the sound to go to my USB sound car in every apps.
I heard about a conf file called audio_policy.conf but I don't really know if it is the solution to force every sound to go to my USB sound card.
Can anyone help me please? I woudl be fantastic if I can make this working.
Thanks

It seems it is not a problem with audio_policy.conf but a drivers problem. The rom doesn't include needed modules :
snd-hwdep.ko
snd-rawmidi.ko
snd-usbmidi-lib.ko
snd-usb-audio.ko
Does someone know how to find it or how to compile it form sources?
If not is it possible for other android HU to check if you have theese files in your HU (Joying, Pumpikin, etc...)in this directory : /system/lib/modules please?
Thanks
Hi, did you find a solution to that issue?
