mic in htc usb converter

[alex jb]

I just used the HTC converter thingy to be able to plug in my 3.5mm jack into the car.
It's the one I got with my diamond, I didn't get one with my TP as it was an e-bay purchase.

I tried to make a call and the other end could not hear me, no mic action.
I thought there was a mic in the converter block?

If there isn't, why did this set up work fine with my diamond, but not the TP?

Is there a seting I can change to keep the phone mic switched on when the converter is plugged in and it takes over audio out duties?

I'm guessing it is because of the way the headset mode is set: it is possible that the connector has 4 terminals: L, R and mic. Since we only use L and R for audio output and no mic the phone assumes that the headset would have the missing one and disconnects the onboard mic (since the headset mic will pick up a better signal). Most phones can do this (use the onboard mic) , it is really odd that HTC did not think about this since it is a easily detectable condition.

what you say makes sense, but, I used the same set up with the diamond and it worked fine?!

Anyone know how I can tell the unboard mic to stay active when the HTC converter unit is plugged in?
