Microphone detection bug?

So I have a 3.5mm jack in my car that connects to the AUX function in the stereo. I used to use this for handsfree with my previous device. (The microphone being used was the phone's microphone, with the 3.5mm jack outputting callers through the car speakers)
Does anyone know how to get the HD2 to properly recognise that the plug being plugged in doesn't have a microphone? It seems to chop off any voice function because the HD2 thinks I've plugged in a headset with a builtin microphone when this one doesn't have that.. It's just a regular 3.5mm jack.
Perhaps a registry hack? Could this be a hardware limitation?
Thanks for any help!

Handsfree calls using headphone jack + internal microphone

One of the features I miss of my Hero that my Nokia N95-8GB had was the ability to plug in a standard pair of headphones (or 3.5mm audio out cable) and use the built in microphone to make hands free calls.
I use the phone a lot in my car whilst driving to and from work to listen to music and would love for it to recognise the standard cable (which it does - indicated by a pair of headphones rather than the headphones/mic icon used to indicate the presence of the hands-free headphones) and be able to automatically answer inbound calls using the internal microphone.
Is there an app for this kind of thing - I'm guessing it is something that is/can be controlled by software?

have you tried it actually? because i use my ipod headphones quite often and it works as expected, sound from headphones and i hold phone closely to my mouth as its using internal mic.

Really not sure what you are looking for. If you plug the standard HTC headphones in using the jack on the top then you can use of the built in mike they have to answer calls.
Or have I missed something?

I've also done exactly what you're asking with my car. I've had my phone in a car holder w/ an audio cable from the Hero's headphone jack to my car's line in jack. I was able to answer calls just fine, and the person on the other end could hear me. (And it was just a standard stereo audio cable, my car doesn't have any sort of built in mic)

im doing the same thing but people on the other end are complaining about an echo of thir voice. I figure its coming from thier voice being picked up by the internal mic. Anybody have any ideas? how can i cut the internal mic while theyare talking. would a cheap wired headset work using its external mic? i could cut the headphones off and splice it into the line in.

I have had my G2 since late September and quickly found out by accident that it does use the internal mic when a headphone is plugged in.
Mine is a simple adaptor from the 3.5 mm into the RCA in my car. If I have the volume up too high, it echoes. If I have the volume down low, I can have a perfect handsfree conversation.
With the headphones I have had problems. In the car, I have the phone laying down and the mic side up. If I am holding the phone in my hand, I have no problems. Shirt pocket, ok. Pants pocket, no way.

Head phone jack makes bluetooth mic not work?

When I have my epic plugged into my car via the head phone jack for playing mp3 the bluetooth mic on my hands free kit stops working. I'm guessing its giving priority to the plug in mic since something is plugged in. any way to change this? I want bluetooth to take priority.

External microphone

I'm getting ready to mount my N7 in the dash of my 97 4Runner where the double din goes. This will block the internal microphone(s).
I will have the 3.5mm jack hooked up to an amplifier for sound.
Is there a bluetooth microphone available to use for voice input and the likes? Id like to somehow sync my phone to the tablet and make phone calls using this mic as well.
I know I could use a bluetooth headset, but I want the audio to go through the 3.5mm jack to my car speakers. Is it possible to make use of just the mic on a BT headset and disable the audio portion?

Anyone?

Maybe you could use a headphone splitter and use a mic like this http://www.amazon.com/External-Bluetooth-Microphone-W01171805-W01176815/dp/B006IL7BCA

There is no mic input on the n7

In line microphone for car install

So I have my nexus 7 installed in my car all nice like. I am using the 3.5mm audio jack for simultaneous audio out as well as microphone in. Basically same wiring you have with an in line mic on a pair of headphones. And I want the mic to use on the home screen to use Google experience launchers "OK google" hot phrase while I'm driving. About half the time it works and half the time it doesn't and reverts back to using the internal microphone. Does anyone have any luck getting the mic to work all the time whole plugged into the audio jack.

Thanks! Ya i'll post a picture of my build when i get time, i posted links to my cables. The audio out and mic in work wonderfully, about half the time... It's definately something in the the android OS that determines when it uses it's build in mic and when it uses the plugged in mic. just not sure how

nice, i'm interested in trying this out too!
