[G3 Q&A, Help & Troubleshooting] McGyver dei poveri:
100% software problem, they made this useless system that tries to distinguish from AUX and PHONES, the sistem works only with some cars.

They have to fix this because it's frustrating, the audio bug explosion when I change audio track + the audio AUX disconnection if you stop the music for more than few seconds, are silly problems that can be fixed easily with an update. With the earphones everything works flawlessly, I have no audio explosions or disconnections.
[G3 Q&A, Help & Troubleshooting] jthein1989:
It is not a software issue. The software doesn't distinguish a difference between AUX or headphones. The problem is hardware related.

The fact that the phone doesn't recognize a blank cable, but does recognize headsets and headphones would be the thing that pops into any electrical techs mind. If you add resistance to the cable by just licking your fingers and holding them on the opposite end of the cable, the phone hardware will register the cable. This means that the hardware itself just doesn't know a cable is there. The reason this didn't happen before on most other phones is that this phones hardware lacks the capability to know when any random cable is connected. It's looking for a bias between ground and either left or right channels.

Older phones determined whether there was a cable simply. The headset port had 2 grounds, when you inserted a cable it would short the grounds and the hardware would report a cable. This is why on older phones you didn't even have to fully insert the cable, as long as the grounds were shorted, say by the tip of the connector, it would report a cable being inserted.

The only reason some cables work and some don't is resistance. Here is the crappy thing, resistance is bad for anything audio related (among with a whole lot more). Cables with high resistance will register, cables with low to no resistance will not register.

The reason it works on some AUX sources and not others is because some AUX sources use resistance before the amplifier, some don't. If they don't you are going to need a crappy cable to add the resistance. Or, if you're tech savvy, add the resistance yourself, that's what I did. Works great!

Crappy cables have resistance, good cables have low to no resistance. You don't always get what you pay for anymore.
[G3 Q&A, Help & Troubleshooting] meherenow:
I have a mixture of crappy and good cables and it makes no odds to the distortion sound I have when play/paused.

I do not have any bother with the actual audio, I always get audio, I do not lose audio after five minutes. The audio sounds fine to me in the car and from an amp.

All seems to boil down to poor quality control on LG's part.
[G3 Q&A, Help & Troubleshooting] McGyver dei poveri:
I knew that was something impedance-related, hahah if the things are like you said they made a high end smartphone without a jack detection system, no I can't believe it.

Anyway your solution of course works, because with headphones no one has problems.

Does anyone have a 2012 Corolla? Definite deal breaker if I can't play music in my car with this phone.
[G3 Q&A, Help & Troubleshooting] McGyver dei poveri:
I noticed that if the phone is plugged into the USB CHARGER the problem of the jack recognition does not persist.

BUG-TEST FOR EVERYONE:

Be sure the phone isn't charging: than plug a audio cable (of any kind) connected to nothing (no amps, no car stereo no phones).

Look if after 10 seconds the symbol of the HEADPHONES or the AUX in the status bar disappears. If it does, there's a bug.

Please repeat the test 2-3 times.

Temporary solution: put on parallel a pair of earphones with the aux. This solves also the "track change explosion" bug.
[G3 Q&A, Help & Troubleshooting] dj_jokke:
I have a Saab 9-3 -00 with original stereo, just added AUX with a adapter kit. For me the problem occurs like this: I plug the cable in - phone recognizes it and displays the AUX cable icon at the top. After a couple of seconds the icon dissappear and I have to unplug the cable again. BUT if I plug it in and immediately start playing music or a podcast, everything works like a charm. This is the only way I can get the phone to realize there is a AUX cable connected and that I want to play music through it.

As you guys previously stated I'm having no troubles with headphones. Also worth mentioning is that the AUX cable I use in my car is high end, so I guess there is pretty much no resistance.
[G3 Q&A, Help & Troubleshooting] McGyver dei poveri:
I found a solution, just look at my last blue message.

Unfortunately today I went to the shop hoping to test another G3, but there weren't :/ so if you would make a test, it would be much appreciated.

Because if it's a problem of production batches I can change it quickly in the first 10 days. :good:
[G3 Q&A, Help & Troubleshooting] BlueC78:
Another "me too". This is consistent with what I am experiencing with regard to the failure to detect that aux is connected. I haven't noticed the noise or distortion but this could be because I have only once managed to get the damn thing to play over aux.

For me it only happens with my car stereo. With other aux devices I have had zero problems, and zero problems using the headphones. As you said, I also figured it is something to do with whether the connected AUX device is "hot" or not at the moment of connection. I need to experiment more to try and discover the exact circumstances in which it happens and hopefully figure out a workaround.

Please update if you find a way to reliably overcome this problem.
[G3 Q&A, Help & Troubleshooting] galt:
Just a note, I'm having the same problems. I've found that I can initiate it to route audio through the car stereo (either initially or when it drops) by just powering the stereo down and back on, which just takes a second.
[G3 Q&A, Help & Troubleshooting] meherenow:
OK, I plugged in an "empty" aux cable, the aux symbol on the status disappeared after 10 secs - however, on replugging (around a dozen times to test it) the symbol stayed lit on the status bar.

Also, I NEVER have had any bother at all with the audio cutting out, or my car or my 2 external amps detecting the (different) cables unlike some of you, it plays the music every time, I only get this audio "explosion" in between tracks.

Are you saying I need one of those "dual" mini jack adapters that split the mini jack between to headphones, and i just have a pair of headphones dangling from the spare socket?
[G3 Q&A, Help & Troubleshooting] McGyver dei poveri:
Yes I solved both problems putting in parallel a pair of (crappy) earphones. No audible audio signal loss noticed.

You can use a jack splitter http://www.autistici.org/ackme/projects/howto/howto_double%20dolby%20surround.it.02/6_sdoppiatore_jack.JPG

But... I honestly hope for a bug fix, it's quite ridicolous this problem.
[G3 Q&A, Help & Troubleshooting] inc0gn3gr0:
I am like 90% sure that having basically a headphone jack extender will fix the problem. Also you can try what my friend has been doing and setting your car to AUX, while on waiting a few seconds and then plugging it in. I have personally had no problems on my car my friend with his G3 is having the trouble.

I still believe it is software as no one is having any trouble with headphones. It is strictly AUX and whatever the G3 does to discern between AUX and headphone is what is messing things up. If someone could simply just remove this and simply make go always headphones or always AUX, I am sure the problem would be solved.

I have yet to have any audio quality issues, when it does work.
[G3 Q&A, Help & Troubleshooting] BlueC78:
I had a mess with it in my car this morning but the behaviour is baffling:

If I connect the aux cable to the handset, with nothing connected on the other end, then the phone displays the AUX connected symbol. This happens reliably 100% of the time and the symbol doesn't disappear.

As soon as I connect the other end to the car aux input, the AUX mode icon disappears on the phone. (WTF?)

The above happens regardless of whether the car head unit is in AUX mode or not at the time of connection.

Somehow, once, I managed to get the handset to properly connect, but I could not recreate it. It was some magical combination of timing between plugging the cable in to the handset, plugging the cable into the head unit, starting music playback, and switching the head unit to AUX mode.

When I tried to recreate the working magical combination the stupid phone kept going in to headphone mode instead of AUX mode and then constantly switches (like every half second) between routing the audio to the internal speaker and the connected AUX output.

As you said, a work-around would be to use a splitter and dummy pair of headphones, but frankly it is ridiculous to have to do that.

And like you, I feel this is a software issue to do with the detection of AUX/Headphone that LG have needlessly and poorly implemented. I am hopeful that an update or an XPosed module could fix it.

I wonder what is so different about my car head unit AUX input (compared to any other AUX input I have tried) that makes the handset refuse to detect it reliably?

I will keep testing it but it is so frustrating it drives me mad!
[G3 Q&A, Help & Troubleshooting] meherenow:
I don't have a splitter handy just now, but I tried hot plugging in the car, with the stereo off and on - all sorts of configurations.

I managed to get the headphone symbol to come up instead of the aux cable, but STILL, the audio bang!

My replacement handset should be here today, but I am not around till later in the week.

On another slightly annoying note, is there any sort of bluetooth auto volume when on calls? I have the volume set quite low when on a bluetooth headset, but in the car bluetooth the level is the same - on my S4 the volume used to automatically get louder if the surrounding was louder, ie when driving at speed. At the moment I am having to manually adjust this on the G3, is there something I'm missing?
[G3 Q&A, Help & Troubleshooting] BlueC78:
Just to add: for me powering the handset by USB makes no difference to its inability to connect to the AUX output.
[G3 Q&A, Help & Troubleshooting] McGyver dei poveri:
Here (in Italy) an update is coming in few days, can't wait to see if solves.

[MENTION=824709]meherenow[/MENTION]

So you asked for a replace unit, well, it will be interesting to see if the audio bang problem goes on or not.
[G3 Q&A, Help & Troubleshooting] meherenow:
Cool, let us know if the update solves anything, I still never heard back from LG UK since they said they were looking into my issues last Thursday.

I won't be able to test my replacement till Friday at the earliest, but I won't hold my breath!

AT&T black G3...picked it up Friday from Best Buy. I tried one set of headphones and they work. However my Dell desktop PC speakers aren't recognized by the G3. They've worked fine for hundreds of hours through my Galaxy S3. I will try other headphones when I get home from work.
[G3 Q&A, Help & Troubleshooting] McGyver dei poveri:
None has problems with headphones.

A possible solution is to make a hard reset, I will try in the next days because it's my brother's phone, not mine.

It's the european version 16GB
[G3 Q&A, Help & Troubleshooting] Dyln:
I tried hard reset but didn't work.

Another strange thing is that it works in my car with one cable, but not on my stereo system with the same cable. With another cable it also works in the car, but its really noisy on my stereo system and the sound pops when i wiggle the cable, and the phone also starts voice search. What's the difference between different audio systems and cables?
[G3 Q&A, Help & Troubleshooting] BlueC78:
Hard reset won't make a difference. I've had 2 handsets and they both behave the same. I think it is not a fault that only affects a few handsets it is a bug that affects them all but only with certain combinations of aux output devices/cables.
[G3 Q&A, Help & Troubleshooting] McGyver dei poveri:
[MENTION=849832]Dyln[/MENTION]

They have different input impedance. You just described my same problems, I have also audio explosions when I skip track if the connection is unstable.

So hard reset didn't work :crying:

we must wait to see what happened at who asked a new unit.

I think it worth the try of a firmware flash with LGMobile support tool.

Anyway I tried 5 setups (from 50 to 5000€) and all have problems of explosions and unstable connection.

I can't believe that I found 5 rare cases, that must be defective production batch or something, or everybody would have noticed this issue.
[G3 Q&A, Help & Troubleshooting] cellbot414:
The first day i used the auxiliary port in my car it worked fine and i got the auxiliary cord icon on the top of my phone. Then later on that evening is when i started experiencing the issues that everyone is reporting. I returned the device to the At&t store and went back to using my optimus g pro. Not being able to listen to music on my phone is definitely a deal breaker.
[G3 Q&A, Help & Troubleshooting] awtryau89:
This is happening with headphones as well. You can see my comments in this thread.

http://xdaforums.com/lg-g3/help/headphones-buzzing-sound-t2811501

I have not had issues in my car because I connect through a Bluetooth receiver but I still think its the same thing. You can check my last post where I have verified a few of the same things you guys are seeing even using headphones.
[G3 Q&A, Help & Troubleshooting] galt:
For now, I installed a cheap little Bluetooth dongle that routes audio back through the aux in the car, and set up Tasker and Nova Launcher to toggle Bluetooth off and on with a home screen gesture. Works better than I expected.
[G3 Q&A, Help & Troubleshooting] inc0gn3gr0:
The humming or buzzing sound is actually a KitKat audio bug, http://xdaforums.com/showthread.php?t=2682189. Any phone on kitkat has some sort of audio bug currently and each company is slowly implementing a fix. The issue with the G3 is that anytime anyone plugs in headphones the phone recognizing them, but when using auxiliary there is a problem as what ever the G3 does to discern between aux and headphones is not working properly resulting in the phone choosing to do nothing.

Personally, I don't mind dealing with it the bug. I just want someone to confirm if it can be fixed with software. One poster has listed good reasons as to why it could be hardware, but it doesn't explain why headphones work so consistently
[G3 Q&A, Help & Troubleshooting] zeddys:
Need Dolby b noise reduction like we used have on tape players. lol:)
[G3 Q&A, Help & Troubleshooting] meherenow:
I can say, categorically, that my particular handset does not choose to do nothing - every time I plug it into any aux source it plays the music perfectly well, except when it comes to a track change, whether that is manually, automatically or if a call has finished - basically any time the music has to be paused, there is this "audio explosion", as best described by McGyver dei poveri.

My replacement handset has arrived, but I am away till Friday so I will have to gnash my teeth till then. :mad:
[G3 Q&A, Help & Troubleshooting] dj_jokke:
I saw someone recommending to try pluging in the aux cable while also charging the device. I can confirm that this works. The aux symbol in the notification bar pops up immediately and doesnt go away, sound plays through the car speakers without hassle.

That pretty much confirms it for me - it has to do with the way the LG software handles the different types of audio connected to the device.
[G3 Q&A, Help & Troubleshooting] McGyver dei poveri:
meherenow, haha I hope that your new G3 will do the same or I have to change mine too.. :/ (I'm joking :P)

It's sad because it was a present for my brother and he will be without phone for weeks before the replacement arrives. Audio quality is maybe the #1 feature that he wants from a smartphone, so I did a bad choice if they don't solve this issue with an OTA hehhehe
[G3 Q&A, Help & Troubleshooting] gorillaz1:
Just confirmed this works for me as well.

Pretty darn annoying.

Anyone have any cheap blue tooth receivers they can recommend for the time being till LG gets this sorted?

Other devices have the same issue running Kitkat.
[G3 Q&A, Help & Troubleshooting] BlueC78:
This thread is getting confusing. There are two issues: the inability for the device to reliably detect a connected aux output and the noise on the aux output. Which are you referring to?
[G3 Q&A, Help & Troubleshooting] 00dahc:
Noise issues. I'd imagine both issues will be fixed in one patch. http://lmgtfy.com/?q=kitkat+audio+issue

UPDATE: I used this "Google search" website to look at other websites on the internets. The Google told me that many other phones have the AUX issue as well. They noted that it came when they updated to Kitkat.
[G3 Q&A, Help & Troubleshooting] McGyver dei poveri:
I can't find other phones with the same aux issue honestly, I don't think it's a known bug, the audio noise could be.
[G3 Q&A, Help & Troubleshooting] enaybee:
I am also having the same problem as described here ...

distortion when switching tracks

I am only not seeing hearing this issue where the track ends while playing music. If there is a "no music/sound" portion at the end of track there is a distortion when the next song is played. I have also tried GPS, everytime voice prompts are said this distortion happens at the beginning and end of prompts. Seems like LG is cutting power to aux cable to save battery (?) but can't be sure ... may be other users could verify this distortion issue before and after voice prompts or switching tracks. I am using a cheap aux cable from walmart that has a generic stereo pin setup (if that matters)
[G3 Q&A, Help & Troubleshooting] BlueC78:
LMGTFY indeed, you cheeky tit. Drop the attitude.

Let me spell this out to you, again.

They are two separate issues:

1) the inability to properly/reliably detect and stay connected to some AUX output devices - this is what this thread is about

2) some noise issue with aux

The first issue is specific to the G3, and is also what this thread is about. The second issue may or may not be more widespread relating to kitkat in general, and is not really the topic of this thread... discussing it here is only adding confusion. I can't read your mind to know which issue you are referring to.

Why don't you go and use that google internet search site and find how to read a thread properly and how to stay on topic?

And why on earth would you believe that both issues would be fixed with "in one patch"? Are you an Android developer with explicit knowledge of what is causing these issues?
[G3 Q&A, Help & Troubleshooting] 00dahc:
Oh. The rest of us are aware that the world doesn't revolve around you and the intention of my post wasn't to make you think that everything is about you. I was just being jovial/jokey.

As stated I said before... both issues are known kitkat issues with devices other than the G3. As seen in my post/link.

I'm sorry that your parents didn't hug you enough growing up.

[G3 Q&A, Help & Troubleshooting] Sporks42:
Found this thread by a Google search for this issue so I created an account just to second (third?) this. Phone recognizes all the headphones I have tried, but didn't recognize the aux cable that was quite happy recognizing the G2. Just turned the car on, plugged it into the car charger, and it recognized the aux cable. It's a little crackly but it plays sound.

Hopefully they fix this soon, but for now I'm just glad to have music in my car again!

Thanks guys!

By the way it's a LG G3 straight of the box from T-Mobile.

Aux Issue

Alright, so for those of you having your LG G3 replaced. It probably won't fix the issue, I just had mine replaced and the issue still exists. Also I have test the aux issue many a times and I have found that it seems to be a resistance issue. This may sound stupid, but plug your aux cable into your phone, and then put the other end slightly into your mouth. I honest to god did this and it shows a constant little aux icon on the phone. Well upon arriving home I plugged my phone into an old crappy cable that I have, and behold the issue is gone. This issue might honestly just be a bug in the software, because they do have some sort of software that is detecting what kind of output device you have plugged in. The reason for my saying this is that no one has had any trouble with headphones, but that is just my two cents. Anyways have a wonderful day all.
[G3 Q&A, Help & Troubleshooting] mwelke@live.de:
Experienced the same, but I use another way to make it work on a device were it won't work normally. I play Music (Spotify, there are no gaps between Songs) then I put the cable into the device, while you can see the Aux Icon appears and then disappears, then I use my fingers to hold the other side of the cable, now I wait till the Icon appears and than I'm putting the cable fast into the Aux-Port of the Radio. Worked every time for me.
[G3 Q&A, Help & Troubleshooting] andy22786:
Another follow up...I used the app SoundAbout and set it to the "Media Audio..." setting to "Wired Headphones". Before I did that I had my speakers plugged in and they weren't being detected. When I made that change the sound instantly came out of the speakers. This confirms to me that it's a software bug. I chatted with LG support the other day and they told me to take it to the local retailer for help....
