hello everyone, my N9 also has the same problem. I have to reset the phone with headphone plugged in everytime i want my phone to be in headphone mode and re-reset it if I want to switch back to speaker mode.

SO i installed the App from Mitrandir (thanks mate, very much appreciated), but it doesn't work on my phone . It was installed without any problem but it simply just doesn't switch to any other mode. (so looks like something is prevent the switching after the OS is loaded).

any idea why this is happening?? I am on PR1.3. It actually worked for me when I was on PR1.1 (i did not update EMMC at the time) and if i remember correctly it started happening after i installed PR1.2 (with EMMC).

any help is appreciated. Thanks alot
