Using for Media Player in Car = Buzzing Sound

I use the phone as my media player in the car. When I plugged it in to the AUX on the car stereo AND it is on the charger there is a buzzing and whining sound. This was almost an instant return. However it seems to be that it is only in that condition if the phone is not outputting any sound. Once I engaged GPS, or MP3s the buzzing sound goes away (not quite but actually gone). I need to test more for long pauses in between navigation prompts, but it seems to be ok as long as some app is planning to make a sound to the headphone port. Maybe a power saving feature?
I never had this with my EVO, my Wife's Epic 4G, or any other phone I have owned.

I experienced the same phenomenon on an LG g2x. Only would buzz when NOT playing sound.
EDIT: not in a car, this was on an A/C adaptor at home.

the noise you are hearing is from the alternator of your car.( the whinning) go in your car hook up your phone and charger and give it some gas, you will hear what i mean. there is nothing wrong with your car or phone, its actually something that is rather common, so dont worry. you can buy a '' 3.5mm ground loop isolator to hook up and it should take that sound away.
hope this helps

using it as a usb drive, is better than the aux input
the phone isnt grounded very well, and will cause some noise issues
and the headphone output really isnt that strong in comparison to the evo series, imo

What receiver are you using? I tried the C3, but when it was fully charged fro some reason the sound goes to crap.

Here is a video of the noise. Note the car is NOT running. All the noise you hear comes from the stereo aux and phone. When I plug in my EVO, or the wife's Epic 4G there is NONE of this.

It really freaks when panning and zooming.

I read this post this AM and decided to do my own testing. I used a Monster Cable 3, a generic Radio Shack cable, and something I found in a parking lot for the AUX, and 3 different car chargers and 2 different ones for the AC tests. I also tested with the music app, navigation, and no apps.
The results:
no apps - popping noises no matter what combination of cables or chargers I used
Music - popping noises when not playing music no matter what combination of cables or chargers I used
Navigation - popping noises when not navigation nowmatter what combination of cables or chargers I used
It seems that if you have something generating sound the popping sounds are gone (or at least mutted to the point where I didn't hear them). Otherwise, you get all sorts of odd noises as reported by other posters.
The car chargers were a BB charger, an iGo charger, and a Motorola charger and the test was repeated with both the engine running and just in AC mode (to keep the chargers active). The AC chargers were the out of box charger and my BB rapid charger.
I also repeated the tests with my wife's Evo and my old BlackBerry tour. Nether of those phones exhibited the same issue although both picked up some minor alternator whine when I was driving.

I can't tell what truck you got splashing through the puddle in your profile, but I am driving (having this issue) in a Nissan Frontier. I too tried several cables and chargers always with the same result. I even ran power from my Motor Cycle and Audio to the Truck AUX and still had noise.
So then I tested this in my wife's car (Chrysler Sebring) and the noise is not there, gone nada. WTH?
I took advice from someone else on this thread and hooked up a Bluetooth receiver to the aux and that works fine.
My conclusion is it must be something between my Nissan Aux and this phone when connected directly.

Poor sound quality with line out, but fine with headphones?

Just bought a used/refurbished Tab 3 7.0 from Amazon.
The sound quality when connected to a stereo cable going to my truck's stereo aux in is VERY poor, scratchy, staticy and only hitting the left channel well.
However, when i try headphones, it sounds fine.
I have, for basic troubleshooting purposes:
-Know that the aux in jack in the truck is fine... it works with my HTC ONE and other devices i've tried.
-Know that the stereo audio cable(s) im using are fine. Again, used them with multiple devices to troubleshoot.
-Used multiple headphones and earphones to troubleshoot. I even used my skull candy's with detachable audio cable, then immediately tried that cable in the truck.
Audio is "tolorable" if the tablet is set to 40% or less, but that requires cranking the truck WAY higher then it should be.
Once i hit 50% of volume, it starts sounding like crap, and once i hit 70% its unusable.
However, with any earphones or headphones, i can push it all the way to 100% without distortion (and no, not wearing them while i do it)
Im thinking a software issue somewhere.
The tablet says "earphones connected" no matter which cable i plug in, headphones or aux cable.
Also, in accessibility the "mono if using a single earpiece" box is UNCHECKED.

I have the exact same issue. Were you able to figure it out?
EDIT: I found this link where safariking made a zip file to remove bloatware. I ran it and my sound is vastly improved.
Good Luck and remove bloatware at your own risk.

Audio Issues when plugged into car First shortcoming I have found

So ive got to say this phone has been pretty much awsome for the past 24 hours but I have found its first major short coming wondering if anybody else is having this issue.
SO here is what happens. I happily plugged my note 4 into the aux audio jack in my car and then I plugged it into the car charger. That is when I get this really annoying electrical noise through the stereo system in the car. So I was like hum that is weird my note 2 only did that if the jack was not plugged in all the way. Well when a sound on the phone plays the electrical noise goes away completely and I hear the sound or song or whatever audio is playing crystal clear. Then as soon as no sounds are playing as if the audio card in the phone is not being used its like it shuts off and lets all this electrical noise coming through the charging system of the phone. Then if say a txt comes in the electrical noise sound goes away the alert plays then after the alert plays the electrical noise comes back super annoying. Can hear the alternator in the car through the noise as well. Make me wonder if it is a software issue of some sort because the noise goes away totally whenever any program takes over the audio driver and plays something through the sound card.
Anybody else have this issue? Try it if ya have not would be interesting to hear reports on this. I do not have bluetooth in my car so could not test it. I always raise the phones volume all the way up when plugged into the aux jack so I have more preamping to the stereo.
Thanks

Haven't tried on the note 4 yet but I did have this same issue on the note 2. But it was more of a white noise. Very low almost TV static noise.

I've had this issue with multiple different phones - I don't think it is the software exactly.
The only time that would ever happen to me is if I was using my aux cable AND had my normal AC charger plugged into it (using an adapter for the car that turned the "smoking thingy" into an AC socket.) If I used an adapter for the car that just gave me a USB port to charge it through only cable it would never happen.
And this happens consistently - haven't tried with my note 4 though yet though.
Try it without your charger plugged in.

I agree without the charger plugged in there is no noise at all. But it is strange that the grounding loop problem only occurs if software is not playing any audio at all. It literally goes away when something plays audio I can hear it go silent then the audio plays then there is another 8th of a second of pure silence then the noise starts again. Or say you are listening to tune in radio or something and a notification comes up. It will pause the radio program and then you will hear the noise for a split second then a sound will play silent again then split second noise then the radio will resume playing. So between the hand off of the two audio programs playing a sound you hear the noise really weird.
I agree the AC adaptor made noise for me as well on the note 2 plugged into an inverter. But this is just my normal 12 v adapter that never had a problem with the note 2. Will be interesting to hear what more ppl say with their 12 v adapters.

My power adapter above 1 amp makes a lot of noise. Had a 2.x amp for quicker charge. Had to revert to 1.x amp charger to reduce noise.

Auxiliary Output Issues

I connect my LG G4 to the auxiliary jack in my car stereo (stock stereo in a 2007 Saab 9-3) with a standard 3.5 mm male to male audio cable. The process to get the audio to come through my speakers is rather cumbersome.
I have to follow this procedure:
1. Unplug the audio cable from the aux jack in the car stereo
2. Plug other end of the audio cable into the phone
3. Open Google Music and press play on the music I want to listen to
4. Plug audio cable back into the aux jack on stereo
5. Change stereo from Radio/band to Aux
I have to do this every single time, and if my music happens to reach the end of the album or playlist to where it is no longer playing anything, I have to repeat the above steps. When I had an HTC One M7 and M8 I didn't have to do any of this. I could just connect my phone and press play...no problems.
I really hate having to do this for two reasons. First, if while driving, I decide to listen to music on my phone rather than the radio, it really distracting and unsafe to mess with while driving. Second, I'm afraid with all the plugging/unplugging on my car stereo is going to wear out the aux jack and degrade the audio quality.
Anyone else having this issue with their G4? Any suggestions? I know someone with a G3 and they don't have any issues like this when plugging into their car stereo, although they have a different car, but I don't think it would really matter.

I do car electronics install for a living... I'm not familiar with how Saab does aux (I don't see many saabs), but in most vehicles there is a 'sense' wire in the aux plug. You will know if it has one because without a cable plugged in, you won't be able to select the aux source. In your case, the residual connection from your phone's fm radio (uses headphone cable as antenna) might be interfering with the 'sense' wire in the aux plug. I would suggest trying a different aux cable, like one with 4 bands instead of 3. They are typically used to carry audio as well as video. If that doesn't work, amazon has these universal Bluetooth receivers that plug into the aux port, which for sure will do what you need it to.
Example of 4 band cable-

The Bluetooth reciever would be my choice though-

The stereo in the model year range of my Saab is basically the same that GM put in Pontiacs and other makes in the 2007 year range. GM owned Saab at the time. I know someone with a Ponitac G6 (I think that is model, it is definitely a Pontiac) and I remember remarking that he had the same stereo as me. The buttons and interface look nearly identical. If I have the aux cable plugged into the stereo I can select the Aux source, even if I don't have anything else connected. If no cable is plugged into the stereo, I cannot select the Aux source.
What I don't understand is why it worked fine with no weird issues with the HTC One M8, but it doesn't work with the G4. Sounds like a software bug to me.
As far as I know Verizon disables the FM receiver in the G4 just like they did in the HTC One M8 and basically all of their phones. It's still in physically in the phone, so maybe it can still interfere in some way, but if it worked on the M8 I don't understand why the G4 is different in this respect.
I'll try a different cable and/or a 4 band cable though and see if it makes a difference.

I used my G4 in my car (2009 RAV4) without issues. I didn't do anything special, just plugged it in then started playing the podcast app. I don't recall if the sequence mattered at all. I typically plug the cable into the phone first, then start playing the audio.
I believe I have a "sense wire" that esmenikmatixx referred to, as I believe my car will not let me select Aux if nothing is plugged into the car. I have an audio cable that I always leave plugged into the car's port, to reduce wear on the jack.
I didn't try the music app in the car, unfortunately. FWIW, Google Music was fine for me with headphones, no weird issues. I have Verizon, but I have since returned my G4, so I can't check anything else for you, sorry.

So I decided to get a bluetooth adapter that plugs into the Aux input on my car stereo and it works great with the exception that the audio volume is ridiculously low. I max out the bluetooth volume on my phone as well as the separate volume on the bluetooth adapter and it is really quiet. Turn up my car stereo you say, but ah, I have to turn my car stereo up to near maximum as well to get a decent volume that could be heard while driving. When I turn the car stereo volume up this loud the speakers become overrun with static and it makes it sound like I'm listening on an FM channel that barely comes in.
I've noticed lower volume over bluetooth on my LG Tone bluetooth earbuds as well. I used these the LG Tone's with my HTC One and had no problems with volume levels. The first time I connected my LG Tones to my LG G4, I had to nearly max out the volume on the Tones (despite having the LG G4 bluetooth volume maxed as well) to hear audio at the same level that I previously did on my HTC One.
So bluetooth is not going to be an answer, the quality is too poor. I dug around on the Play Store and found an app called "Soundabout". The app will allow you to force your audio out through whatever source you want even when the output device is not connected. I set it to force audio through wired headset and it works for the most part. I don't have to do any weird unplugging and re-plugging of audio cable just plug and play. The only thing is that sometimes when I connect the phone and press play on a song you can tell that Soundabout is fighting with the crap software on the phone to force the audio to the wired headset (wired speakers) because the audio will cut in and out and then stop. After pressing play enough times that it wins out, it will finally go through the wired connection. The one downside is that if I'm out of my car and want to listen to something through the speaker on the phone I have to go back into the Soundabout app and change the output to "let the app decide".
So, I'm 100% sure it is something with the software on the phone. There is little doubt. I have no problems with any other phone connected to my car stereo. It's not like I have some aftermarket stereo. This stereo is as stock and basic as you can get. When they designed the audio controls and functionality on this phone they didn't put a lot of thought into it. It's frustrating because otherwise this is a great phone I just hate messing with this stupid audio issue. All I can do is hope it's patched. There are no built-in options on the phone to tweak audio settings.
I can't imagine I'm the only one having problems like this.

LG Customer Support has been predictably unhelpful. I may just return this and get a different phone if I still can.

Same for me. Works fine in my 2008 Subaru. I've run everything from local mp3 files to Audible to iHeartRadio and Pandora through it without a problem. Even the Smart Settings for auto-starting Audible actually work.

I plugged it in with an audio cable to my girlfriend's Mazda and it works fine. Guess I'm S.O.L. Highly unlikely LG would patch this if it's software due to being so isolated. Would be interested to hear from those with a mid to late 2000's GM vehicle since they all have basically the same stereo as Saab. Maybe it is an issue with my stereo, but I don't understand then why other phones work just fine.
Frustrating because there is nothing I can do to fix it other than spend a bunch of money to replace my stereo which I can't afford, or spend an equal amount of a bunch of money to pay off the G4 so that I can get a different phone to then make more payments on, and Verizon absolutely, no exceptions, refuses to exchange it for something like a Galaxy, Note 4, anything different than a G4 because I'm 5 days past the 14 day return period. Guess I only have myself to kick in the ass for not doing sooner, but I wish someone at Verizon was kindhearted enough to make an exception.
Sorry for venting.

Sorry to hear about the issues. Did you try the 4 band cable idea?

Not yet, but I will. I've been reading on another website that the G3, last year's model, had this exact same problem. There's a thread with tons of people reporting the same problem. Some used a cable like this one which was suggested earlier and it solved their issue. Suppose I should have tried that to begin with. I'm going to try this one: http://www.amazon.com/gp/product/B00K36XWG0?psc=1&redirect=true&ref_=od_aui_detailpages00
I'll report back if it worked or not at least so that if others come across this they have a starting point.

I got the 4 pole to 3 pole audio cable today and it doesn't work. I tried flipping the cable around and it still didn't work. I don't know what else to try, anyone have suggestions?

Kevin 82485, late on this thread but I just purchased a 2007 Saab 9-3 and I'm having the same issues with my LG G4. I just downloaded the soundabout app you mentioned, but have you found a better solution than that?

2007 saab 9-5 and LG Aristo on Metro PCS. Same issue as OP. Its definitely a LG issue, wifes Galaxy works without issues, no fiddling with the cable and audio pausing and plugging unplugging plugging and trying to play audio. Good phone, garbage audio coding.

External HiFi USB-C DAC not working properly

Hi!
Last week I received the Pixel 2 XL, which seems to me a nearly perfect phone.
The only problem to me is the lack of 3,5mm jack output. Given the poor sound quality of Google's dongle, I decided to buy a HiFi solution, recommended by most audiophile people I know, the Sabre 9018 USB-C DAC by Hifimedy.
And now, there comes the issue. When I plug the USB DAC to the phone, it works flawlessly... for a few seconds. In fact, the sound is quite great for the price. But, after a few seconds or when the song changes, the sound stops. The song keeps playing in the phone, but there is no sound in the headphones, although the red light in the DAC suggests it is still receiving energy from the phone. I've used many apps, like Tidal, Play Music, Poweramp, Spotify, VLC... and it's the same with all of them.
I don't know if there is a way to force sound to keep flowing through the USB port, or if it's an issue caused by oreo's energy management, but neither the DAC's manufacturer nor the Google support know why it happens.
You guys are my last resort. If nobody here can hint a solution to the problem, I will have to battle with the DAC manufacturer to get a refund.
Thanks very much in advance for any help that may come!

Try to restart the Phone it should Work after it
Try Not to Start the Phone with the DAC in or dont Plug in the If Music is playing
If U want an other Hifi DAC that Supports the Pixel and have a pretty good build quality:
NEXUM AQUA

Thank you for your help, but I restarted the phone, resetted it, and the Hifimediy DAC still does not work.
I think I will go for a refund, it seems the DAC isn't compatible with the Pixel 2.
I'll have a look at that Nexum Aqua you pointed out.
