I'm using the Desire as music player in mine auto. It's connected via aux to the stereo and works well, but when I connect the usb car charger begin a loud noise...that's connected directly with the car motor, because more high are the rpm and more is loud this noise
What I can do for solve this problem?
Same thing here, it has always been this way even with my old Nokias, HTCs, MP3 players... it's an interference you can't suppress, while charging and using an audio cable to AUX IN.
ps. I'd really like to be proven wrong by someone else who finds a solution for me, either!
By the way, how do you handle hands-free? You hear callers voices but you have no mic to speak in so they can't hear you.
Do you know any way to use Desire's mic as input AND 3.5mm-audio-out as output?
You need a noise filter! Google "car stereo noise filter", thye're cheap.
I dont get this, but I used to in my old car.
Its easy, you need a noise supressor on the line - what you are hearing is alternator whine (a whine that changes in pitch with the RPM speed on the car).

You need a "ground loop isolator", get one cheap with the connections you require from ebay.

Doens't exist a car charger that includes this "ground loop isolator"?
I have been researching online about using car aux-in cable for making phone calls.
I heard that some phones work and some do not. In those cases, when it doesn't work, it means that the person in the phone cannot hear what you say, because by default the mic is muted when something is plugged in to the jack.
With HTC Sensation, does this happen? Is the phone mic muted when a headset/aux cable is plugged in to the phone? If yes, is there any workaround? What is the general solution to make phone calls via aux cable?
I heard that some people might use the griffin cable with mic, but since my aux port is located where the shifter is, I am not sure how the quality would be. Any idea?
Thanks

well, i hope this answers ur question
i have made calls/received calls via aux (when im listening to music in da car n get a phone call i dont uplug it, just answer)
i talk thru the mic normally and i hear the other person from tha car speakers.
so i guess the mic is not muted
From previous experience - though not with Sensation, as I'm all blue-tooth now, the following was true
If you plug in a normal 3.5mm TRS jack (stereo headphone / line-in / etc) the phone detects it as headphones and not headset, so the device realised there was no "in-line" mic, and used the phone's microphone itself.
A better option (which I did) was to fashion my own lead - using another HTC headset, but removing the two earphones, and soldering the cables to an in-line socket. This worked well, because I had a microphone clipped to me, with remote control for music (don't want to touch the phone when driving now, do we!!) and the stereo audio feed back to the car speakers. Cost me about £3 in total, including the second headset.
I would imagine this to be the same for the Sensation too, as all these sockets have various detection mechanisms, to make the right things happen, depending on what you connect.
Good luck, and safe driving!
hey guys,
my One S has buzzing noise coming from the headphone jack, and this problem is pretty annoying especially when it's connected to my car stereo. I thought it might be just mine, but it seems like this is a common issue.
i found this video on youtube. I have the exact same buzz from my One S, though perhaps not as accentuated as in this video.
seems like the One X has this problem as well. found this thread at the One X board http://forum.xda-developers.com/showthread.php?t=1720212
is this a grounding problem in the headphone jack? Beats Audio? what do you guys think?
I've always had this problem with more than one phone. If you charge the phone via USB adapter from the car battery, it gets 10x worse.
This problem only happens when sound is being played back, so when music/video/game sound kick in, it stops. Do you get that noise when sound is being played back?

The buzz is only audible when nothing is playing. Like in that video, when I stop playing music it will be silent for about 2 seconds and then the buzz kicks in again.
I didn't have this issue with other phones
I don't have any buzz, I double checked just to make sure.
Although it might be my headphones, the output is probably not strong enough to play the sound.
It's probably being heard in your car (or in the youtube video) because the output is being amplified.
I'm having the same issue with YouTube and Pandora.

you're right. the issue isn't as noticeable through earbuds. i think that's why many people are saying they don't have this issue. It's still bad though.
I don't know why HTC messed up this part when no other phones seem to have this issue. Makes me sad.
If it's easy to reproduce for you guys, I'd definitely be pushing for warranty replacement.
I do not have this problem at all. On my cheap pair of headphones or on my expensive one. No hum or sound.
the buzz is there, and it also was on my Desire.
Not when playing tho, only when connected and not playing. Not too annoying, always thought it was supposed to be like that.
And no, I have never heard it through ear buds or phones, only when connected to home stereo or car stereo, and if charged through cig-lighter-outlet it amplifies further...

It doesnt effect headphones, only when the sound is amplified. Like when you play music in your car.
Simply because that sound alone is not enough to drive the headphones.

Whether its plugged in to a car or home stereo, its still using the output from the headphone jack. The power output from the jack is the same either way.
I plug mine in to the aux jack of my car stereo daily, and I have no buzz or hum. Do you have your phone plugged in to a power source at the same time? That buzz is usually caused by crosstalk from a poor quality power source.
Or, as I said earlier, it may just be a bad phone.

Well my phone doesnt do it in my headphones. I can't test in car, no aux input.
What I was saying is that, of its buzzing in your car but not on your headphones its because the sound level at which the buzz is at isn't enough to drive your ear buds. But when the car stereo amplifies it its easily driving your car speakers.

So when I insert my headphones into my Optimus P509 it doesn't "grip" the jack. The slightest bump dislodges the jack and disconnects the headphones. I can't hardly take two steps without my headphones disconnecting, especially if I've got the phone in my pocket. I've tried several different sets of headphones and then tried the same headphones on my wife's iPhone and am only having the problem with my P509.
Is this a fairly common problem? Any suggestions for a fix?
Hi everyone, I got my new mix 2s this week and I am sad to say it has audio problems when using the included usb-C Jack adapter.
My car is equipped with a sony stereo with a front facing AUX in, a cdx-gt33u. So, as soon as i plug the phone in the aux in, there's a hiss, a loud white noise. After some seconds that the screen is locked or the phone isn't sending any audio the noise stops. When I play music the noise starts again and covers the music as it is louder.
I tried every cable I had, even in a friend's car with a similar stereo unit and the problem is the same. With a TRRS cable (one with also the microphone's ring) there are also clicks and pops.
I would like to keep this phone as I really like it (and I can't find any good alternative for about 500€) but I found no fix. I'm considering returning the device as I work with audio professionally and not being able to play music in my car is just ridiculous.
What's your experience? Did I get a broken device or is it a software issue?
MIUI version is MIUI Global 9.5 Stable (9.5.19.0 (ODGMIFA)
EDIT: I considered installing another rom or rooting to apply the "<ctl name="RX HPH Mode" value="CLS_H_HIFI" /> Replace CLS_H_HIFI with CLS_H_LP"" fix, but I bought the phone less than a week ago and rooting it just to listen music doesn't seem reasonable to me.
It's working just fine in my cars audio in... However, the LG G6 my girlfriend owns has the same problem with my car that you just described
I don't experience any audio problems when using the USB Audio Adaptor with wired headphones. Car audio systems sometimes have issues though when you hook up a phone with a wired sound connection. I think a grounding issue creates the noise.

You are totally right. Yesterday I bought a ground loop isolator and the problem is gone.
I also got a small bluetooth receiver to put into my stereo aux in. Quality is worse but at least I can just leave it in the car without having to worry about adapters! (now I have to worry about its battery though)
This jack-less technology is leading us in a really uncomfortable direction but I guess we have to live with it.

I agree unfortunately. Phone device manufacturers and headphone makers seem to have decided that we're going to have to use Bluetooth whether we want to or not.

You could leave the adapter in your glove compartment in case the battery runs down on your Bluetooth receiver.
Ive got a bluetooth receiver in my glove box powered by usb from my head unit so it turns on/off with the stereo. Its arguable that audio is worse using bt if you have aptx codec or even better aptx-hd which is virtually lossless. Using the dac in the phone could induce more noise because if the space constraints in a phone and proximity or rf components. Having a good quality Bluetooth receiver with a quality dac could be better. Best of all is a usb dac though.
