How? Bluetooth Headphone and Phone Mic

Hello all i paired my carkit to my n900.works all fine but the microphone of the my car radio is very bad so i want to use the phone mic instead. so i modified etc/bluetooth/audio.conf and i added this line:
Disable=Headset

now my n900 sees my carkit as a bluetooth headphone. which is what i wanted . but now when i receive a call it uses the phone speaker and phone mic and not my car speakers.

does any1 know how i can fix this?

Re: Use phone mic with bluetooth headphone

i am no coder but it seems like to disable all the features of the headset

Re: Use phone mic with bluetooth headphone

It should work cause mp3 does work.
so the voice should go throught the phone mic and the audio to my radio with a2dp

Re: Use phone mic with bluetooth headphone

Does anyone know if you connect a bluetooth headphone to your n900 and you receive a call you can hear the audio through the bt headphone??

Re: Use phone mic with bluetooth headphone

This is a little off topic but does the same go for a wired headphone? Im assuming the headphone jack is multi-function, as in will carry both the mic and stereo audio, so if you plug in just a stereo audio cable that the mic will continue to be used off the phone? The reason I ask is that I have a similar setup in my car but no bluetooth. I have an ipod adapter that syncs up to my stereo and has a line in for aux input. If I could plug into that and get audio out the car speakers and continue to use the mic on the phone thatd be awesome. Im assuming there will be echo / feedback depending on how well the phone mic noise cancells.

whats the alsa_sink.mixer???

Re: Use phone mic with bluetooth headphone

have you found a solution for this problem? Because i am trying to do the same thing now and i can't get it to work

Re: Use phone mic with bluetooth headphone

I have found the solution. It is to edit the file
/var/lib/pulse-nokia/hs.parameters

and make sure your line looks like this:

Code:

x-maemo.alsa_sink.mixer_control = "HP DAC:control,Headphone:off,Earphone:on"

Works for me :)

Re: Use phone mic with bluetooth headphone

You can type:

Code:

alsamixer -c 0

To play with the sound mixer manually. I used it to do some cool stuff such as playing audio files through the earphone.
The effects are only temporary so if you screw something up, just reboot your phone.
