Disable headset mute

[webPragmatist]

I have a three connector headset dongle that allows me to connect my USB, Headphones, and Headset.

Is it possible to disable the phones disabling of the phone Mic when this dongle is present?

I know I can alter the headset connector by unsoldering the headset wire (which is makes the phone switch to headset mic when it is grounded) but was wondering if there was an easier way.

Thanks!

No.
If you removed that wire it wouldn't disable the internal mic, but it wouldn't deactivate the internal speaker nor activate the headphones.

That's why there are better dongles that have a mic inside ;)

Maybe I wasn't very clear.

I have one of these... http://images.marketplaceadvisor.channeladvisor.com/hi/61/61482/CHTCS620AD01_it_L.jpg

and I am only using it for power and headphones (so two of the connectors).

When I use the adapter I cannot use the internal microphone because it thinks there is also a headset connected to the 3rd port.

I can't find the diagram (which may be helpful) but what happens is the mic is shorted to ground when you plug in this adapter... I am not sure if reading that the mic is shorted is a hardware or software "switch" though.

Nope you were clear and I understood it right, but maybe I wasn't...

When you plug a headset into the Kaiser, there's a contact in the plug that tells it it's present, which makes it deactivate its internal mic and speaker, and activate the headset output and mic input.

If you removed that contact the internal mic would work but you'd have no sound in the headphones.
In this adapter the mic input is not shorted but connected to the 3rd plug you're not using, so that when you plud a standard HTC headset there its mic will be used.

As you're not alone in your situation, some better adapters have a mic in their body so that you can talk even without connecting the headset, which you'd want to do.

I am not so sure about this because if I remember correctly (after taking apart my connector) there is groundable connection specifically for the mic. The reason I am doubtful is realistically there's no reason the headphone output should ever cease.

Unfortunately I have already buried the connector and use bluetooth so it happens to default to that mic anyway.

Just out of curiousity do you have the pinout for this device handy?

Edit: Attached the pinout (took longer to find than expected)

I disected the little pushy talky (yes... i know... real technical) headset connector I have and I have mixed feelings about this mic issue.

Let me clarify that the end product is an adaptor that allows for audio listening but uses the internal mic.

Now, the reason I have mixed feelings is that it's actually the device deciding to play audio through those two left/right channel wires. For instance, take voice commander and hit your voice command button. The device keeps the audio opened but without the "switch" being grounded.

I didn't want to completely destroy this adaptor so I will bust out the soldering iron tommorrow and play. :D

Edit: the issue was really killing my curiousity so I cut the little mic that came from the headset off. I was still able to say a voice command using the internal mic BUT let me make a note that I think something voice command is doing is allowing audio to playback through the headsets even though the volume is turned to vibrate.

Maybe there is something about the two other ground connectors that need to be addressed.

Anyone else have some light to shine on the subject?

Well, I have a similar issue. I have an adapter too (build into the car holder) and sometimes I want to be able to listen to music or the navigation voice via the line in of my car radio. At other times I want to listen to a CD in the Radio and only occationally hear the navigation voice via the internal device speaker. I have tried to de-solder some of the pins to find out which one it is to sense a headset to be able to put in a little switch so I can select where I want to have the audio but failed so far. Has anyone got any tips which contact(s) I need to switch? Thx.
---Thinking about it, is there even a software switch I could use to disable the headset? (BTW Iam using a TouchPro)---
---More to this: Others have asked about similar too, e.g. http://forum.xda-developers.com/showthread.php?t=418713. But what makes me even more curious is the fact that we the device is cinnected to the adapter it thinks that there is an antenna connected too and allows radio use (so no need for the reg hack to enable this) but then in the Radio application you can enable the speaker and then you can listen to it via the speakers.......so there must be something in software ......?
