anyone knows what does this app do? it shows up in task manager while charging in stock rom. I don't think that there can be any noise while charging. :/
I guess there could be RFI from the charger, or maybe it's something to do with thee downtime settings or the quiet times in the moto assist app.

It could be associated with the audio amp or DAC's within the device, so as to suppress the high frequency ripple on the 5v from the charger caused by it's switching frequency. There must have been an issue with it at some point during development.

It mutes the audio from the headphone jack when charging (if no app is using it). Before they added it (it's really a patch), you would hear buzzing from an automobile's electrical system through the stereo if you were charging and were using the headphone jack as a line out to the "aux" input on a car stereo. If you don't ever connect the headphone jack to your car stereo, then you shouldn't need it anyway.

Is there anyway I can talk through the phone's mic and listen with ordinary head phones?
I can do this with pretty much any recent Nokia or iPhone, but the i9000 just seems to ignore normal headphones completely when answering a call.
This looks more like a software thing.
some phones doesn't work like that, you can listen but not talk when using the 3.5mm headphone (without mic)
like my old Palm Treo phones you can only use it unplug, or plug but then your headset will need to have a mic, else it wont work.
the next best thing is Stereo Bluetooth, they all come with a Mic
Not even that much
That's the thing, on the Galaxy S can't even "listen" to the phone call using headphones.

Thank you for your help, but what I'd really like to do is connect Galaxy to my car stereo's 3.5mm input and answer the calls using the car speakers.
I know that if I used a Nokia Mic adapter, it should work, but CRAP!
This is a way too expensive phone not to do that without the need for an adapter.
I have faith someone will come up with a way to bypass Samsung's stupidity and just leave the audio jack active when in a call.
Also, if I want to use my Sennheiser HD headphones, I can't without putting a crappy adapter between it and the telephone.
if it's for the car, then just get bluetooth for the car, it's by far the easiest way
The easiest way is a 25cent cable
The easiest way is a 25cent cable that does not eat up my battery like BT.
Again, I thank you for your help, but the perfect world would be someone to flip a switch in the phone's software and just make sound come out of it.
You are right; I also had my Hero connected with the 3.5mm cable to my car stereo and when I received a call, I switched my car to AUX and picked up the call, presto! Sound was routed through speakers and mic would pick up my voice perfectly.
Now with my new SGS it just doesn't work! I must leave the cable disconnected and switch the phone speaker mode on to be able to talk. How sh*t is that?
So here I was excited about a 3.5mm jack. Oh well. Just shows to go ya, size doesn't matter.

Hey,
Can you please elaborate on that cable wiring? or where to purchase etc?
I think the best thing is have an adapter with a mic and a female headphones socket to which you connect ANY headphones.
Just a followup on this, my old n95 adapter works perfect.

it's kinda weird. it works and it doesn't.
i have a jvc in-ear earphones and skullcandy lowrider headphone.
when receiving a call with my jvc, audio switches back to the phone's speaker and phone mic won't work unless i unplug the jvc.
with the skullcandy lowriders, call is routed to headphones and phone mic work perfectly.
note: neither of these pairs have an in-line mic, so the mic i am referring to is the one on the phone.

Nokia? Nope... on that thread I posted about the SAMSUNG adaptor http://forum.xda-developers.com/showpost.php?p=7350178&postcount=22 I use this in the car via the aux port - works perfectly and for £2.95 you cant go wrong.
I am experiencing the same problem, which is very annoying and might keep me from buying Samsung again if they don't provide a fix...

It weird indeed.
I tested an iPhone stock headset (which has the exact same jack as the galaxy S headset, at least visually), and the calls are not ROUTED through the headphones !
A possible explanation for this is that the phone monitors the headphone's impedance: if the impedance is different from the one of the stock headset, then call sound is routed to the phone speaker.
I'm really hoping some developers will come up with a fix or a custom ROM to fix this issue.
i'll post the specs of both headphones for scrutiny when i grt home.
one thing i can day though is that my jvc has 10mm drivers and my lowrider has 40mm drivers. does that even matter?
i'm also gonna try to see what happens of i use my bro's skullcandy asym in-ears.

Any news about this issue?
I am about to throw this phone against the wall because oh this.... Damn!!!!
If there are things which should not be considered "as features", this is one of those...
sorry but it took me a while. first, here are the specs:
skullcandy lowrider
driver: 40mm
freq response: 18 Hz - 20 kHz
impedance: 32 Ohms
Max Input Power: 400mW
jvc HA-FXC80
Driver Unit: 0.23"(5.8mm)
Magnet type: Neodymium
Frequency Response: 8HZ - 25KHz
Impedance: 16ohms
Sensitivity: 103dB/1mW
Max Input Power: 150mW(IEC)
skullcandy asym
Driver Unit: 13mm
Frequency Response: 18Hz - 20kHz
Impedance: 32 ohms
Max Input Power: 30mW
and one more thing i tried...
x-mini max speakers
Drivers: 40mm
Frequency response: 230HZ -18KHZ
Sensitivity: 86db/1mW
Out of all the four, the calls would only route to the skullcandy lowrider. At first I though it might have been driver size, that's why i threw in the x-mini max for the test. looks like there's another factor that's causing this anomaly.
It's definitely soft problem! Because in Nimbuzz software, if you use Nimbuzz-out (same as Skype-out) and i had phone connected to car with 3.5 mm jack, sound went to car stereo, and i was talking using samsung mic. So if they could realize this "feature", why samsung couldn't?
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).

As in you (the people in the car) can hear the other person on the line, but not the other way around? Happens to everyone with this phone-if the device (in this case the car) you're connecting to doesn't have a mic then you're screwed - the charge doesn't allow you to use the integrated mic.

Not sure. Maybe the microphone on the phone is being blocked. Does the speakerphone function work properly when it's not plugged into the car?
Yeah the speaker phone part works, but it's a 2009 corolla car... I didn't know if there's a setting in the charge
Maybe the phone recognizes the car aux port as a speaker / mic combo instead of just a speaker.

Try using regular headphones on the phone and see if the other person can hear you. If it does work then you will probably just need to use a different cable to plug into the car.

Actually I have no problems doing that. I tested it once and it worked fine for me. I had the phone in my lap making shure the phone mic was not covered. Just had to speek a bit lauder. The max distance from face to mic in phone should not b more than 1.5ft. At 2ft you would need to yel to b heard. At least that was my expirience.

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.

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.
