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,

[Resolved] Question re car stereo, aux and bluetooth

I have a feeling that this can't be done (because I looked into it with my XDA Exec a few years ago), but....
Is there any way that I can play mp3s via the extUSB into a car stereo (via an AUX in) and yet answer calls via the same stereo's integrated bluetooth via the headset profile?
The stereo would normally drop the AUX in sound for a bluetooth call, but clearly the extUSB would normally handle calls if a audio output device is plugged into it. With my Exec, I seem to remember that the hardwired audio output would be the default, and so the bluetooth would never engage.
If there is a hardware solution, I would be very keen to know! Even better if the extUSB also charged my Vario IV in a passive holder.

What about playing music through the blue tooth of your car stereo? Tricking the car into thinking its actually engaged in a call so it plays music. Might have to be something done on the phone side to transmit the music as a call and then when you receive a call the music stops and you can answer the call and when the call ends music resumes? Just a thought i dont know if it is possible at all. But you bring up a really good idea.

Thanks for the thought, but the stereo doesn't accept bluetooth streams - it simply just has the ability to act as a hands free device.
Any more thoughts anyone? (Although someone has just posted about a device that looks intriguing with AUX and power in)

It's definitely doable. Thats what I've done with my non BT Pioneer deck. Check out my post here - http://forum.xda-developers.com/showthread.php?p=3278241#post3278241.
Hope this helps.

Thank you too for the feedback, but I can't see a bluetooth device in your chain. Perhaps I wasn't clear in the original post, but in the end I suppose the question is can calls be handled over bluetooth when there is any audio outpu device plugged into the extUSB?

Sorry. My bad. You are right, I did misread your post.

the answer is yes. that is what i do daily.
i listen to music through quality wired headphones, and when a call comes in i use my bt headset WITHOUT unplugging the headphones from extUSB.
all you need to do is answer the call using the answer button on your bt headset and not your phone.
in some phones, if you will press the send key on the phone and not the bt headset, the call will transfer to the phone instead of the bt headset.
hope i was able to help.

Thank you.
Do you think it matters that you're using headphones rather than a headset? I'm just wondering, since you refer to headphones, if the lack of speaker in your wired device means the call will hand over to the BT device - this will allow me to work out what I need to buy.

hmm i think since your aux input wont really have a mic attached it should hand over the call to the bluetooth headset from what the other person is saying.

Hi, I don't know if this will apply to your stereo setup but I thought I would let you know my setup anyway.
I use the HTC multifunction audio cable http://www.expansys.com/p.aspx?i=171925 which lets me charge my phone via a car charger and use the 3.5mm audio output to the stereos aux input at the same time - all of which are in center armrest compartment.
I use bluetooth connection to the factory installed bluetooth prep (BMW 3-Series). When a call comes in the TP pauses the audio and the BT phone then takes over. When the call ends the TP un-pauses the audio

I just installed a Blaupunkt MP57 on Sunday and did exactly what you're describing. Phone connected via aux playing music, answer or make calls via bluetooth on the stereo and the music pauses then restarts when the call is ended.

Both can send all outgoing audio from your WM device via BT headset channel instead of A2DP. It's not advanced audio but it will let you play audio over the headset BT channel. Sound can be tweaked using SRS WOW HD.
ExtUSB is just a port which will enable playing MP3 tracks on for example USB drive? Why not put your connection in USB mode then?

I'm not sure if this will help you, but I bought a Motorola Bluetooth Car Kit. I don't have the "phone" feature built into my car Stereo, so I used the external amplified speaker and mic for "phone" functions. The Car Kit has an Aux Out, with I feed into my car stereo. When I get into the car, the Bluetooth initiates two separate "connections". One for the "phone" and one for the "MP3 Player". You can have either one or both. The music plays through the car stereo (via the Aux Input) and phone calls play the the external Car Kit Speaker. It is like having two independent bluetooth "channels". When I have Voice Commander enabled, it communicates through the "phone" channel, i.e., the Car Kit mic and external speaker. That is also where my incoming email is announced through. My Garmin GPS "speaks" through the Aux out and the Car Stereo though. I'm not sure how these routes are selected. Personally, I would prefer that the GPS also communicated through the "phone" channel, that way if I am listening to the Radio, or Sirius, or a CD (not on AUX-IN), I would still here the GPS voice guidance. I'm not sure if that can be changed or not.
Hope this helps.

I do this all the time. USB to 3.5mm stereo to Pioneer head unit and calls come in over the BT

Thanks all for the input.
Just bought a Brando adaptor:
http://www.inkino.co.uk/zen/index.php?main_page=product_info&cPath=126&products_id=1502
Tested it and Copilot and Music run from the Aux out. Bluetooth hand over perfectly. As an aside, I find WMP is a better MP3 player, simply because I can reduce the volume in the software, but leave Copilot to use the system volume at a slightly higher level so the voice doesn't get lost (the HTC player doesn't seem to have the same capability).
Could have bought the HTC branded device from the same place, but the main lead from the Ext USB is slightly longer and more inflexible so wouldn't easily fit under my car holder.
BTW, since I live close to the shop (plus I love instant gratification as opposed to mail order), I visited the Inkino shop in London. I must say that the staff were very knowledgeable and helpful and the shop has a huge range of HTC accessories (including a branded battery and extended battery for my Universal, which I am planning to resurrect). Not sure about the prices vs ebay, but for the bricks and mortar approach in the UK, where it is difficult to find anything HTC - 1st class!

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...

Phone call audio not routing through 3.5mm jack audio cable or headphones

This is a general appeal for ideas, but mostly directed at Havoc [Havoc-OS v2.8 2019-09-09] users - I need your help. I've searched high and low for a solution and at this point I need someone else using Havoc to confirm something for me. The issue is phone call audio routing when headphones or 3.5mm audio cable is plugged in. On my old S2 for many years when I was driving I'd connect an audio cable to the 3.5mm jack and it would send audio (music, audiobooks, podcasts etc) to my car stereo. Then if I made or received a phone call, the audio from the other party would also come through the car stereo and the phone mic would easily pick up my voice a metre or so away, just like it would on speakerphone mode for a regular call.
Now I have an issue with the Note 4 where all regular audio out, music etc, will go to the car stereo but for some reason it isn't routing phone call audio to the car stereo OR the phone's external speaker. They can hear me fine from the Note 4 mic but I hear nothing. In addition, the call recording reveals that their voice IS being recorded along with mine....but there's no way for me to hear them.
I have tested this at home as well with regular wired headphones (not the handsfree type designed for phones with a mic on the cable), just plain old headphones I use to listen to stuff at the PC. The same thing happens: music and other normal audio goes to headphones but I cannot hear any audio in a call.
This is weird and I can't figure it out. My old S2 did this effortlessly for many years through multiple different ROMs and still does it now running Nougat. In my searches I came across what appears to be a solution, one of the only apps of it's kind for many years called SoundAbout, but it crashes straight away on my phone, and I read the same complaint from several users on Oreo onwards. The app seems to have been abandoned by it's dev years ago.
I've looked everywhere in Havoc settings and I can't find anything obvious that addresses the issue so I'm turning it over to you smart people. Any ideas? Before you say something like "just use a bluetooth headset in the car" - No. I'm not looking to change anything, I just want this (very simple) thing to work as it has for years, since Gingerbread! Btw, I only discovered this today for the first time as I'd never tried it before so I have no idea if it would have worked on earlier versions of Havoc or any of the Oreo ROMs I ran.
Thanks guys.
TLDR - [Havoc-OS v2.8 2019-09-09] phone call audio not routing to car stereo via 3.5mm jack, all other audio goes out just fine.
