Headphone jack not working

Hello,

I bought a Samsung Galaxy S2 to try Replicant.
Unfortunately, I did not try the headphone jack before flashing replicant.
Now I don't know, if the hardware is broken, or is there a known issue with replicant?

Symptom description: The headphone jack has no function whatsoever. There is no reaction,
when I plug in the jack; the music is still playing on the phones speaker.

Is there a way to force the output to the headphone?
Just in case only the plug-in event is somehow broken.

I have the SGS2 (i9100), too. If I plug in my headphones into my Replicant 4.2 OS, the toggle-event is triggered automatically, and my headphones will be successfully used.

I've found some apps, (I didn't tried) for manually toggle testing:

https://f-droid.org/repository/browse/?fdid=com.dwalkes.android.toggleheadset2 (sadly seems to be incompatible with Android versions higher than 4.0.3)
https://play.google.com/store/apps/details?id=com.chislonchow.toggleheadp (based on toggleheadset2, but isn't open source; you could ask the developer to free the code)
https://play.google.com/store/apps/details?id=com.woodslink.android.wiredheadphoneroutingfix (seems to be what you need, but sadly isn't open source, too)

Ad hoc, I can't find a command to do what these apps provide.

One last thing I tried this second. I installed this app: https://f-droid.org/repository/browse/?fdid=ch.blinkenlights.android.vanillaplug (you don't have to install the Vanilla Music player). With this app installed I got an toaster notification on my screen on putting my headphones in, which could help you answering you basic question.

Happy testing.
