Interestingly, when I plug in my Diamond's extUSB dongle, and then plug in my 3.5mm, the button ceases to function. However, I can confirm that I can in fact have two headphones plugged in simultaneously and both will play.



Updated: Without any boot tricks, 3.5 mm jack on phone is not detected at all, and there is no reaction to headphone insertion or removal.

However, extUSB actually does cause some reactions. Plugging in the extUSB adapter has no immediate effect, but if 3.5mm headphones are plugged into it, there seem to be two possible outcomes, and I'm not able to readily figure out the conditions that cause each. (1) While the Android player continues to play, no sound is heard anywhere, (2) music on the speakerphone continues at a barely audible level, even at max volume, and will be covered by a quiet crackling static.

On disconnect of the headphones or the extUSB, Android detects this and pauses any playing music. If any attempt is made to play music again before giving Android some time off (maybe around 5-10 secs) to recover, no sound, not even crackling quiet sound, is played anywhere. If Android has enough time off with the music paused, it will resume playing from the speakerphone.

Thanks a lot dood. This helps a great deal. I experienced the same and i wanted to verify i wasn't on crack. So this sounds like a sound routing issue because one time i noticed when i plugged in the 11pin, all sound was routed to the phone front speaker.

I'm narrowing the 3.5mm now, so hopefully i have something to test soon.
