KJam Microphone switches off when connected to car stereo

Hi,
I have connected my KJam to my car stereo via a cable from the 2.5mm jack to the aux port of my car stereo. Tom Tom voice and phone calls are routed through my car stereo. Sometimes, the microphone will not work when I take a call. I can hear the caller perfectly but they can't hear me. Other times, the phone functionality works perfectly and we can both hear each other great.
If anyone can suggest any ideas, I would be very grateful.
Thanks

if your using a jack to connect it to your car, then its will prob. stop the mic working as its routing the audio to you car in the same way the headset with mic that you got with the k-jam does. I had this problem on mine, but due to the fact that i use a bluetooth neadset in the car fixed that little problem 8)

That's the end of my k-jam desires then.
I use my MDA compact in the same way you describe, for TomTom, Hands free calling and to play my music through.... and my microphone works fine with the headphone jack in.
I guess one thing to check would be the number of rings on your 2.5mm jack. If you have 3 then theres a possibility the k-jam thinks you have a mic on the end of the wire. If you have 2 rings (normal stereo headphones) then there must be another issue somewhere.

thanks for your replies. My concern was around the fact that sometimes the microphone works and sometimes not. I wonder if there is a workaround or a specific type of cable that I need to ensure that only the audio is routed and not the mic as well.
Thanks for all your help.l

never tried this myself, so i can only assume it would work. you could hack a cheap wired headset up, removing the earpieces but leaving the microphone. then add a stereo 3.5 plug so you can hook it up to your car stereo.

I have that very problem also, it's gotten that annoying that i've stopped using it through my stereo. you are able to get around it by popping the cable out of the kjam, then putting it back in.
pain in the ass though none the less.

What is the phone is set to Speakerphone ?
Even though Speakerphone is currently not working...

Hey all,
Just wondering if anyone has had any success in fixing this problem? I am having the same issue. I have a 2 ring 2.5-3.5mm adapter connected (so it should only be routing the audio, not the mic) and sometimes the caller can hear me, sometimes not. At one stage I found by unplugging the cable, setting to speakerphone, then unsetting speakerphone and plugging the cable back in would get it to work, but not anymore...
Any ideas?!?! I love my XDAII mini but this is driving me up the wall!
Cheers,

Notification of wired headset removal

Is there a way to detect when a wired headset has been removed? I'd like to write a program to stop audio playback if the headphones are unplugged, since it's pretty embarrassing to have the music blaring out of the speaker.
I figured this should be possible since the phone itself can detect the presence of a headset to know whether to auto-pickup a call. (This is for the apache, though i imagine the function call would be the same for other devices as well.) Thanks.

any ideas?

That's cool to have, but on the HTC Magician, the earpiece is just a normal 2.5mm with mic, plus a answer button, plugging it in doesn't have any visible notification on the phone.
It might work for yours, but I'm not sure about all other devices.

On WM5 just use the state and notification broker. State is saved in the registry.
For WM2003 you have to go at a much lower level I think.

If someone is writing an apps, please include for wireless bluetooth stereo headset when lose bluetooth connections.

I think this would be a really useful program, especially for Universal owners as sometimes when we disconnect the wired headset, the phone still thinks that it is plugged in and thus we cannot hear any notifications.

Hmm - that's what I thought too, but it looks like (at least on the Apache) that there is no such state. One of the other threads referenced a state named "Headset", but I can't seem to find it.
Nonetheless, the phone must know whether the headset is plugged in, because it prevents you from turning on the speakerphone if the heaset is in.

Any ideas?

you are right!... i will do some work on this and see what happens

Reroute Sound to Speaker with a headset plug plugged in

It seems I can not find a way to route the sound to the internal speaker when a (headset)plug is connected to the phone. I would like to use the phone for conf calls with a docking station as well as for charging as listening to music. For the conf calls I need the internall speaker to work but it seems this is not possible when connected to a docking station with a sound plug.
Rerouting software like this one does not work with a plug plugged in.
teksoftco.com > AudioRoute 1.2.020
Does anyone know of a way to make this work? I was alrady amazed that this was not available in S2P or Windows mediaplayer before but now it is really annoying for calls. This basic functionality was already on 4 year old Sony Ericsson phones.
Many thanks
Update: I tried the rerouting with a bluetooth headset and it does not work. I am unable to reroute a call that is answered in a headset back to the phone

Has anyone actually gotten this yet? Ive got an HTC Apache I really need this done to, the back speaker went out i need to see if i can make it ring from the earpiece.

How does MyTouch 4G deal with headphones with no mic and how to favour bluetooth?

Hi,
I've been using the Car Dock Home v3 app launched from HTC's car dock when I'm driving. Yesterday I was also listening to some podcasts form the phone by connecting the headphone jack to my car's aux input. I had a bluetooth headset connected.
Then someone decided to call me and it was disastrous. The car mode causes the phone to read the incoming phone number and let you answer or decline by voice, which is neat, but instead of going through the car's speaker (headphone out) it goes through the built in speaker. I don't know why it would do this, but with the car noise it was impossible to hear it.
Then after answering the call, instead of going through the bluetooth headset, I heard the caller through the car's speakers (sounded great) but they couldn't hear me at all. I can switch to the bluetooth headset manually, but it's too dangerous to try and navigate the tiny buttons and text while driving. With another caller they could hear me, though.
So I can't figure out what the phone is doing when you have something plugged into the headphone jack but no wired mic. It seems like the phone's microphone is active, but not in speakerphone mode, so it's probably too quiet on the other end to clearly hear me unless I talk right into the mic, which I can't do while driving.
So questions:
1. Is there any way to increase the internal mic gain to use the phone connected to the car speakers as a true speakerphone (and can this be done without creating echo/feedback)?
2. Is there any way to have the phone automatically prioritize a connected bluetooth device over the headphone jack?
3. If the answers to 1. and 2. are no, is there any way to have a car mode specific dialer screen with nice big buttons for selecting audio source manually?
4. Can I get the car mode to read incoming call info into the headphone jack rather than the internal speaker?
Thanks!

Key action you must take when your phone rings...
DON'T touch the screen. Click your BT device to answer.

Are you sure that works? I didn't try that, but I used my bluetooth headset to launch genius and dial a contact by voice. Everything worked through the bluetooth headset, but once the call connected, it switched to the car's speakers.

I'm pretty sure that the car mode initiates hands-free mode, which automatically turns on the phones internal speaker when a call comes in. See if there's a setting that prevents hands-free from turning on in the app. That might fix things the way you use them.

While the phone is ringing, activate the connection via BT. It works for me now, and it worked on the stock ROM. But you don't ned to take my word for it, just try it.

I'll give that I try when I get a chance. There is an option to automatically enable speakerphone in the car dock app, so maybe disabling that will also fix the problem. However, so long as the headphone jack isn't in use, it works exactly like I want it to:
If the bluetooth headset is connected, it gets used for answering and making calls. If the bluetooth headset is not connected, when answering or making calls the phone's spakerphone is automatically enabled.
The issue is that with the headphone jack in use, it seems to take precedence over both internal speakerphone and bluetooth headset.
My guess is that if the headphone jack is in use the phone assumes that you're using a wired headphone/headset with its own mic. If that were the case, the behaviour actually makes sense: if you've got a wired headset in your ears, that's where you'd want the audio to go. I suppose if there is no external mic but you're wearing headphones, using the internal mic without speakerphone gain also may make sense: you'd hear through the headphones and hold the mic near your mouth to talk. The problem is it ignores the case of external speakers versus headphones. Especially in car mode it should be smarter about how it deals with these options. Of course, some of the issue may be due to the third party dock app, so maybe I'll have to try with that disabled or contact the developer to see if he can do anything.
It's little usability issues like this that make me want to drop Android, although I have no idea if there's actually anything that really works better.

Training yourself to touch the earpiece instead of the phone to answer is not overly difficult. It only took me one or two "oops" experiences to stop touching the phone.

I use the phone and aux input all the time while driving, but the difference is that I don't have a bluetooth headset involved.
Audio comes out of the headphone jack and I speak into the phone's mic and it works fine. Turn the phone volume to max and use the headunit volume to adjust.

So I have had a chance to test it. It's true, if you use the bluetooth headset's button to answer a call it does get properly routed to the headset. If you answer by taping answer on the screen it gets routed the headphone/speaker + internal mic.
It does also seem like the internal mic is used correctly and pretty much sounds as good as the speaker phone mode, so answering a call while wearing headphones or using speakers doesn't seem like it should be a problem (assuming echo isn't an issue with speakers). Don't know why that one caller couldn't hear me, but that could be some other reason.
What doesn't work, though, is initiating a call from the bluetooth headset if the headphone jack is in use. Using the bluetooth headset button to initiate genius voice dialing works as expected until the call is connected, at which pint it then gets routed to the headphone/mic instead of the bluetooth headset. There doesn't seem to be any way around this. Of course, since you are initiating the call, it's probably not too bad to just unplug the headphone jack first...

[Q] Bluetooth Headset for Phone, and Audio Jack for Music

Hi all,
Basically, I'm trying to figure out if the subject is possible.
What is happening now is that if I have a standard stereo audio cable plugged in (non-mic) with BT connected to a headset and I receive a call, the audio for the call goes through the headset jack instead of the BT, and because of that there is no mic to pick up my voice. This leaves me able to hear the caller, but them not able to hear me.
Any thoughts?
Thanks,
Ben

Had sort of the same thing happen to me, except I tried making a BT call while plugged into headphone jack and other end was plugged into my car's aux port. Started to make the call and quit. Guess its another limitation of the current set of roms, if I'm reading correctly.
My question is under android I would have a microphone on the keyboard so that if I was going to navigate somewhere I could just hit that and say where I wanted to go instead of typing out a long address. I am using HTC Locations, and don't see any provision for allowing me to speak my destination point.

I don't think that's possible yet, but there is a lot in the way of BT profile and audio settings that may help that. we'd probably want to look for something that doesn't auto cut off when a jack is inserted
as it stands, BT is buggered (music playback) on ultrafruit ROMs anyway so we're not missing much, xbmods ROM worked fine but his left for pastures new and everyone else is being silent on the matter.
