So I use an aux cable for audio in my car. I can make calls through the speakers this way. Sometimes though the Mic doesn't work and sometimes it does. Does anyone know if there is something that specially triggers the Mic to work?

Sounds like a loose cable connection. Normally those 3.5mm jacks have 3 or 4 sections on them to support stereo audio plus a mic. If your cable was plugged in and got yanked to the side, it might break some wires in the cable or bend the plug internally (phone or car). But I'm speculating here...got another cable you can try?

I've got a problem when I plug my HTC Titan into my car stereo as well as cigarette adapter.
I'm also got a kind of custom setup using the HTC Y Adapter with a 2.5mm jack and MiniUSB jack
Audio
Honda Civic Stock Stereo -> CD Changer to Aux Input Adapter -> 3.5mm to 2.5mm adapter -> 2.5mm input on HTC Y adapter.
Power
Belkin Cig. Lighter to USB Female Port (From old iPaq) -> HTC Stock Sync/Charge USB cable -> MiniUSB input on HTC Y adapter.
So, when both the power and audio are plugged in, I hear a horrible hiss on my car stereo, not to mention a sound that varies in pitch to my throttle. When I unplug the power, the audio is completely clean. To me this seems like some kind of a grounding issue - to say that the Audio and Power both have seperate grounds, and bridging the two creates a potential difference in the form of noise on my Sound. Also to note: I only hear the noise when the Y adapter is plugged into the phone. With the audio and power plugged into the Y adapter, but the Y adapter not plugged into the phone, It's perfectly clean. I'm kind of baffeled.
The only solution I can think of is to gut the Belkin Power->USB adapter, and providing it from 12VDC elsewhere. I've got a tap directly below my passenger seat where I have a big power inverter tied to my battery. I don't know if I'd hear the same sound by grabbing my power from there.
Anyone with an engineering mindset have an idea? I'm open to suggestions.
You are right, you have a problem with ground.
I have the same problem with a mp3 player. When I plug the audio + power I have noise, just audio is fine.
You may try the inverter as it would probably filter the noise you're getting from the DC power in your car.
you just nead an in car ground loop isolator used for getting rid of noise on the low level signal to amplifiers.They are just a 1:1 audio transformer
Any incar hifi shop or ebay will have plenty.
I have the same problem, with a polaris using standard headphones. I'm thinking the polaris itself has issues dealing with audio+charging
i had the same problem with an ipod charger, sent the car to the wreckers, and woot, problem solved sorry that was no help
Usually happens when the signal wires (mm adapters + input cord) aren't shielded and pick up the magnetic field from the ground resulting in the engine noise. Sometimes, making sure the signal wires are not touching the power cord and keeping them separated might help. I'm not really sure, since I'm a 100% noob too all this. Let me know what your fix is. I'm not too hip on all the car audio stuff anymore, but if you wanna put some hydraulics in your ride, then I can definitely help you out.
more likely the problem is in the phone, so ...
Hi!
I have this for some time: http://www.amazon.com/gp/product/B0...&pf_rd_t=101&pf_rd_p=470938811&pf_rd_i=507846
(Actually, I baught it in a store so I'm not sure it's excatly the same but it looks the same)
Recently, I baught this one:
http://www.amazon.co.uk/Headphone-HTC-VIVA-exclusive-Duragadget/dp/B001LIM8F0/ref=pd_rhf_p_t_2
When I plug the old one in my HTC Touch Cruise and then stereo headphones, to it's 3.5mm jack (without microphone), I can use phone's mic and plugged headphones to talk.
When I do the same with new one I can't use phone's mic. I can hear the other side through headphones but I can't be heard.
What might be a reason for this?
And can I fix this problem somehow so I don't have to unplug headphones each time I want to talk if I'm listening to the music?
Thank you very much in advance!
P.S. FM Radio works with both adapters.
there is no std for 3.5mm mini-jack with mic included
the org spc is only audio out
some headset makers add another ring which don't interfere with the
left, right and ground connectors
but there is no std they can follow
thumb rule is if mic is not mentioned in relation with the 3.5mm adaptor
mic is not supported as they use the pure audio out mini-jack std
thumb rule 2 is if mic is mentioned but it's not the same manufactures
in both end they may not implement mic in 3.5mm the same way and it will
only work with audio out
Thank you for your quick answer but I'm not sure you understood me.
I do not use external mic.
In first case I use 3in1 adapter and my stereo headphone with 3.5mm connector without microphone.
In second case I use this simple in-line adapter and same headphones.
In first case, during call, I can hear the other side through headphones, and the other side hears me through built-in-phone microphone.
In second case, during call, I can hear the other side through headphones, but other side can't hear me.
In both cases FM radio works well. I mention this because I saw that mic and FM antenna are on the same pin in USBext (if that's important since I don't use external mic)
about fm then all it needs is an antenna connected to to it
any stereo maybe even mono connected with a wire will do
heck you can cut off the airplugs from a cable and use it for fm
normaly when one connects a headset speaker and mic on the device itself
are muted
even if it's a headset without mic so cool that your fist case works at all
This first one adapter is original HTC. It has 2.5mm, 3.5mm, USBext for data and charging and USBext for headset connectors. And unfortunately it is too big for any other use except in car (to connect to car's audio aux input) or at home (to connect to home AV reciever).
So I baught this cheap simple in-line adapter. And it is suprisingly well built. And it works great as stereo adapter. Only problem is that it turns of microphone.
Anyhow I did some additional testing.
I tried SE Xperia X1 since it has built in 3.5mm connector. and it works like this first one. That means microphone works.
I also tried plugging this first adapter into my touch cruise and then plugging this second adapter into it's USBext for headset. The result is the same as if I plug second adapter directly into touch cruise. Microphone doesn't work.
Interesting thing is that in all cases (including Xperia) when I listen to the music with external headphones soudn comes only out of them. But when phone starts ringing sound comes from both headphones and from built-in-phone external speaker.
!!! Maybe the most important thing is that microphone doesn't work even if only second adapter is plugged into the phone, without headphones plugged in it.
Obviously this second non-HTC adapter doesn't work as HTC originally planned that kind of adapter to work and now I need a way to fix this.
It seems to me that this adapter is maybe stereo adapter with mic, but I don't have that kind of headset to try it. And if I had it I'm not sure it would be the right one since there's no standard for them.
As I see it when I plug in adapter phone somehow detects it and changes some registry key which mutes microphone.
Does anybody know what to change in registry so that phone doesn't mute microphone?
Or how can I see what changes in registry when I plug in the adapter?
Do you think if I manage to fix this, will that affect bluetooth headset also?
Thank you very much for any help!
I'm after an adapter to work with my WinMo device which allows me to connect up my own Mic.
The one that almost fits the bill is this ExtUSB 3-in-1 Adaptor but the problem is with the Mic!
I have my own Mic already wired in and a fair way from where the adapter is going to be located. Ideally, I just need a 3.5mm jack for the Mic to go into, just like the 3.5mm jack for the audio out.
The final result being I have a handsfree solution in the car, connected up through the car stereo speakers and a handsfree mic.
Can anyone see any issues with this setup? Does anyone know where I can obtain such an adapter?
1) I tried that adapter with my Touch PRO and it messed up somehow the audio managment so after plugging it in once - after receiving a call I could speak but the device become totally unresponsive only reset worked until a next call... so I hard reseted device and bought the HTC original one.
2) You might get a ground loop when using audio together with charging. I have had it with different cars, devices (laptops/handhelds). The ground loop will give you loud unwanted digital noise while charging. There are workarounds but might not be easy to reach. Basically you need to get the power from the SAME WIRE as the amplifier does.
I have this exact setup in my car and it does work, no feedback problems. I also have the same problem of microphone placement. I have been unable to find an adaptor or a microphone with a long enough wire to do what I wanted, so I had to modify my microphone placement(put it on the dash as oppossed to my sun visor where I wanted it). Other than that issue, it does work great, sounds great over the stereo(both phone calls and music), and charges up at the same time. If you do find either an adaptor or a stupid mini usb microphone with about a 4 foot wire, let me know.

How about the charging?... Is there any change in the audio when plugging in? Try lowering the vol of device as low as possible and maximize the vol of amp.
not at all. The way I have it set up, it is charging or powered the whole time. Of the 3 inputs on the adaptor, one goes to the aux in on my car stereo, one goes to a car power adaptor I installed under the dash, and the 3rd goes to the microphone. I have bluetooth on, so it works with the gps reciever I have(I have an older model without built in gps) and I programed 1 of the buttons to turn on the gps program. Another button is programed to turn on the audio player(I think it is pocket player), which feeds audio to the car stereo anytime I have the aux button pressed on the car stereo. When a phone call comes in, the song pauses and all I have to do is hit the little green answer button on the phone to use it as a speakerphone. Audio is great. I have all the wires snake into one of those little pockets on the dash so there are not a lot of wires going everywhere. Takes about 5-10 seconds to set it up when I get in the car, and about 3 seconds to disconnect when I leave.
I want to take an old set of headphones and cut the headphones off and make an fm antenna out of the cord and plug. Once I plug the cord in however, will it still let me use my bluetooth stero headset to listen the the radio?

I'm not positive, but I believe that when you plug into the headphone jack, it overrides the option for bluetooth.
Not to mention, if you just cut the headphones off, there won't be a complete circuit. If the phone doesn't detect a circuit, it may not even recognize that the wire is plugged in. If you cut the phones off and twist the wires together, it would make a circuit, but MAY cause a short, potentially damaging the phone. I know the signal to the headphones is a very low voltage, but with no resistance at all, it may be enough to do damage.

I'm not sure that's right. If I remember correctly, FM only requires a dipole antenna (single wire, ie a car antenna), and AM requires a loop antenna. Also, I know that none of my headphones create a closed circuit, that's what the little black bars are on the plugs, they separate the different connections from touching, hence you get stereo sound.

There are 3 contacts (The metal part between the black separations) on a Headphone plug. +Left, +Right, and -Common (Used both L and R). A Stereo Phone headset has 4 contact points ( +L, +R, Mic and -Common) The Speaker in a headphone acts as a resistor in the complete circuit from the +L to -Common and +R to -Common. While it is true that FM doesn't require a loop antenna, the Phone, which requires a headset to be used as an antenna will not recognize there is a headphone connected if there is no circuit. (If there is no Speaker between the positive and negative lead of the headphone wire)
To add to this, if you use a regular headphone, rather than a phone headset, it doesn't make a very good connection, and has very limited, if any FM reception.
With regard to the bluetooth question, all you need to do is connect to bt after you plug in the headphones. I believe the evo just outputs to the last connected item.
Why bother cutting up the headphones and then not being sure if it works. Just leave the headphones plugged on as is and connect to you bt.

Thanks to all for you input. I was going to remove the headset because I wanted to make an antenna that I could carry in my pocket when walking without the bulky headphones sticking out of my pocket.

Pick up a cheap set of earbuds. They are small enough they shouldn't be too bulky in your pocket.
Hi, so i tried playing music on my car with an aux cable and there is no sound but when i use my old Galaxy s3 music plays just fine.
I thought the problem was with my htc phone. Can anyone help me please?
Did you check that:
The volume is set correctly on the phone?. It will auto reduce the volume if it senses a headphone jack has been plugged in.
Headphones work with the phone?.
Bluetooth is OFF or not paired to the system?.

Do standard wired headphones work?
Yeah, headphones working just fine with the m9 and my volume was set to a maximum level but music plays through the phone speakers instead of the car's stereo.
Aux lead. Either not pushed in all the way (the last click will feel like your about to snap something) OR It's not compatible..
Just found an aux lead hidden in my car and that's no signal from this phone too.. I think the aux lead is too old and needs replacing with a newer model. Most likely a compatibility issue between the jack plug and socket. Further illustrated by the lack of mode switching by the phone. Basically it's not detecting the jack plug.
I presume if I started cutting wires and jack plugs up then I'd get it working in no time at all..
