Hi Fi Quad DAC damaging AUX cables? - LG V20 Questions & Answers

Hey everyone, I'm an LG V20 owner who loves my device, but I keep noticing that my AUX cables keep getting damaged when listening to music in my car. I thought I'd ask if anyone else was having similar issues. When I say "damaged" I mean that I either have to play with the AUX cable to get it to work or sometimes I only hear sounds from the left or right speakers. I have the Hi Fi Quad DAC enabled and I usually have the phone volume all the way to 75 (max) when I'm in the car. I've gone through at least 3 AUX cables and I'm assuming its either because of the Hi FI Quad DAC or because I have the volume too loud. Are there any good high quality AUX cables that anyone can recommend (preferably from Amazon lol)?

Not possible.
Damage to the cable would have to be physical, either you're using them in a way that stressed them and caused shorts, or you're just buying really cheap cables. You're sure it's the cables and not a problem with the headphone jack or the aux input in your car? Are the cables fully inserted? They're not coming loose?
I've used UGREEN cable in the past and they seem fairly robust

@thisisjason thanks for the response, the cables are fully inserted and not loose. I don't have any issues when I listen to music in my headphones so I'm blaming the AUX cables lol. I'll give UGREEN a try!

I've been using the same aux cable with my V20 since day one. This same aux cable has also been in use with my Nexus 6 it's entire lifetime. I doubt it is the DAC. 99.9% of the time, it's usually due to repeated bending in the same spot of the cord breaking wires. In fact, when used in a car we tend to always place our devices in the same spot which means any cords attached will bend... at the same spot, each and every time. This will lead to the wires inside breaking. Since they're in a sheath, they still stand a small chance of continuing to make contact. Which can make a signal come and go depending on how close the ends are.

If your headphones work fine then you should get a new aux cable, otherwise, it's the headphones jack

Strange, I recently posted about how an aux cable failed on me, I only got full volume / stereo from it when the phone was grounded through USB. Not plugged in, just ground to ground.
It's probably all just a coincidence coincidence since these cables often spend their lives in hot cars, It it's so.ething.

I thought i was the only one experiencing this but i figured its just cheap cables no more than $10. how can i raise volume to 100

can't, when dac is enable, the volume should be louder so the max vol will be 75

[Q] Playback through Car aux connection

I play audio podcasts through car's aux in and just plug in the other end to my Focus's headphone jack. I have noticed that many times the podcast suddenly lowers volume to nearly inaudible levels and happens intermittently.
Once the problem shows up if I
- play songs, the volume level is fine
- stop and start playback of podcast, the problem persists.
- unplug and continue playback on Focus' speaker, the volume level is just fine
- unplug and plug it back in and the problem goes away.
- never have this problem when playing back over headphones (when in gym)
I have this problem only with Podcasts and don't get it at all with songs or videos.
Anyone else noticed this?
Audio output sucks on this phone, that is for sure. Major issues. Sorry to hear about yours.

how so? i'm not having any problems at all.
Did any of you notice it's not your standard 35mm jack? The headphones that come with the phone are clearly deeper than the standard jack, and have two bands around it instead of the normal one.
I presume you are using standard cable to connect to car's aux jack....
I would check to see if there is a special samsung accessory to make the proprietary jack into a standard aux output?
Samsung are notorious for using this style of jack on their phones. The Galaxy line of android phones use the same jack.

that is weird. i hook mine up to my car with the same jack i used for my iphone with no problems. in fact i am under the assumption the sound quality is actually better than with the iphone.
maybe this is a canada thing?
The plug is set up to use headsets with the microphone, and may not work well with some older stereo audio cables. However, I have used it with a podcast and found it to work quite well. I suggest trying another cable, cuz the Focus works fine.
The line level output of the 3.5mm jack is approx. 40% less than that of the iphone, or my HTC Tilt2. That is the issue I have and that others have commented on.
For instance, iphone plugged in playing on my car stereo, Panteras Cemetary Gates @ 320kbps MP3 is mind boggling loud at 50% volume on the car and 100% volume on the iphone. With the Focus the car stereo volume needs to be at 90% to be equal to the volume of the iphone.
Also, since the Focus needs to be at 100% and the car stereo nearly 100% you hear the phones whining, hissing and popping and every non-music portion.
Super lame.
There's some volume problems that I've noticed on the Focus, in that it's not consistent through playback sessions and such.
The iPhone 4 uses a Cirrus Logic codec with an integrated headphone amplifier, the Focus seems to use the built-in codec with it's headphone amplifier, which might not have the same amount of oomph.
I've measured a 7-8dB lower volume on the Focus when using a line-out cable to an Audio Precision test machine.
Thanks for reporting that! Great post.
Does anyone have this problem?
Ok, I have a mp3 car adaptor that I used with my Tilt and Tilt2 without any problems. Rich sound and bass. I plugged in my Focus (just got it last night) and music only comes out one speaker.
In my '95 M3, I run an Alpine HU (9814 IIRC) with a Line in Adaptor, I run very HD (thick) gold plated lines and a Splitter (all from Monoprice.com, one goes to my portable Sirius, other pops up by my center console sunglass cubby, split happens under the passeger seat) and I usually have my 120Gb Zune attached to it, but I tried with the Phone the other day and it worked great. Played a Tool concert and it sounded as good as the Zune. Like the Zune I set the volume to about 80%, still had plenty of head room for serious volume in the Alpine. (only way to listen to Tool is LOUD!) I do run an old school Pioneer Amp, Pioneer Kevlar Components, 2 JL Audio Stealth Boxes (each is an 8" Sub).
I want to escalate this issue but I need you guys to quickly reply on the MS forums so that it gets taken seriously. Please hit the "I need an answer too" button and give some sort of descriptive reply.

I hope that his is a software side optimization since we are able to make the volume higher with the diagnostic codes.
I added my vote there.

I have a second complaint. When I stick a headphone jack in the mic turns off, it probably is expecting an inline mic with the headphones. My problem is when I then go to pull out my headphones the phone doesn't notice and will continue to not hear. It takes two or three times reinserting and pulling out the headphones to remidy this. Is anyone else haveing this issue.

Same problem here. But is worst, I connect the Focus to my Car Auxiliary jack to use it as a mega speaker, I mean, when someone calls I can hear them, but they can not hear me. The microphone is dead when I plug it in. Someone knows a fix for this?

Can't say that I have a fix for it, but it may be the connection your cable is making with the jack in the phone. I do the same thing, have the phone mounted in a jack around the same height as my head unit and people hear me fine when I speak during a call. I am currently using a cable from radioshack designed for recessed headphone jacks. Can't think of the brand off the top of my head however.

Hi pal, thanks for the reply, but I couldn't understand very well your explanation. What is a recessed headphone jack? What is the head unit?
Thanks in advance!
I have not noticed this problem however the microphone shutting off is very annoying and funny since at&t says texting while driving is unsafe yet i have to unplug my phone while driving to turn on speaker and talk. they need to fix that ASAP

Audio Distortion Under Certain Circumstances

I use my phone as an audio player quite a bit, but I've recently noticed and issue and I was wondering if anyone else had similar problems or perhaps even overcome them. When I have my Vibrant plugged in to a power source and I plug in my headphones everything sounds fine, but if I'm plugged in to power and connect a line out cable (e.g. a male to male cable for connecting to a car stereo) I get a really nasty hiss as well as other audio artifacts. I have tried numerous combinations of different power and audio cables, headphones, and audio sinks (car stereo, home stereo, computer audio in, etc.), but the result is always consistent.
Power + AUX cable = bad audio
Power + Headphones = Good audio
AUX Cable - Power = Good Audio
Has anyone else seen/solved this with their phones?
I assume you are talking about car charger and aux out and the noise that increases as your speed increases. If that's what you are talking about I get it to. Something needs to be grounded. Exactly what I don't know. I would ask a car audio person. If I'm not mistaken all radio components ie. radio amp are grounded that's why you don't hear it. Let me make this clear nothing is broken. More like this configuration was not planned for. I'm thinking the cig lighter is not grounded by car maker. Hope this helped.
In the car audio world I seem to recall some issues with Pioneer units when an owner somehow accidentally made a bad connection. It seems that a tiny fusible link in the unit would blow, and a ground loop noise would get introduced into the system. The fix was to ground the RCA cable inputs to the stereo chassis.
Not a viable solution in this case. I also recognize this may have little direct bearing on the problem, but wonder if somehow a poor power/audio connector in the unit is/has caused the same sort of problem to rear it's ugly head.
Step 1 I think - Do you have another Aux cable to test that as a poor ground on it may have developed from just bending and twisting in normal use.
Go to radio shack and pick up a ground loop isolator. That will get rid of the feedback noise.

I also have the same sound in my car. I remember way back when I thought I was a cool kid and rocked the big subwoofers in my trunk I had the same noise. Then I learned that you couldn't have the power cable running up to the battery and rca cables going to the head unit next to each other. You had to have them separated meaning one would have to go along driver side n the other along passenger side. I tried that and presto no more noise. Its the interference of electricity generated from the alternator. Hence, Faster the engine/ alternator goes, higher the noise pitch equalling more interferance due to the higher voltage/current running thru the power cable. Sorry for all that useless info lol!! Quick fix is don't have the power cable plugged in at the same time. The sound goes away, for me at least. Hope it works for you. Other than that I wouldn't really know how to fix it with a cell phone unless that isolator thingy that the other guy said to buy would work.

You should tweet @supercurio
if anyone would know, he would
This has nothing to do with software. This is basically electrical interference in audio channel because the audio is not grounded and power plug from cigarette lighter USB is grounded. Get the isolator, they are usually less than $20, just make sure all the inputs/outputs are what's compatible with your setup.
Mine plugs into AUX port on the car, then i have a 3.5mm Y splitter, one end for phone/mp3 player the other for Sat radio.
Thanks for the tips guys; I think I'll pick up an isolator and give that a try. Unfortunately, the local Radio Shack only stocks isolators for RCA jacks, not 3.5mm, so I'll have to wait at least a few more days until it gets here.
The isolator finally showed up, and it worked perfectly. Thanks again for the advice.
Sweet, now get a flux capacitor and find a straight stretch of road. At 88 mph you'll be going at 88mph with a flux capacitor!

Headphone cable launches google voice search

This is in my car. I have a pretty high quality headphone cable to connect the phone to my car to listen to music. Every time I plug in the cable the phone it launches google voice search, I can easily dismiss it and everything is fine but it also prevents me from using Google voice search after this.
I'm quite certain it has something to do with the phone thinking I'm plugging in a headset that also has a microphone. The thing is I've used the same setup for both the N4 and N5 with no problems.
Is there a fix for this? Or anyone else experience anything similar? I'll have to try out some new cables.
Me too. I think it is a a headset thing like you said. I would like a solution for this problem as well.
I had this issue myself. This is actually caused by a poor ground on the 3.5mm jack on the stereo system itself which is causing feedback to loop back to the phone. The phone picks up on this and thinks you just pressed a button on a headset, even if there isn't a button to press.
You have a few options:
Stream via Bluetooth if supported, and ditch the cable all together. Expect slightly less than optimal audio quality.
Break open the stereo and run a better ground to a part that isn't inside the stereo. This will void your warranty on the your car stereo.
Buy one of these, and re-wire the 3.5mm jack. This is what I ended up doing (more about this later).
If you end up doing #3, you can just plug it in and go, without any warranty voiding stuff, however it looks ugly having that box thing hang down. Here's what I did to make it look a whole lot better, but also voids warranty.
Separate the female 3.5mm jack from the stereo face plate and the radio hardware.
Disassemble the female 3.5mm headphone jack so that it's no longer flush with the plastic face plate.
Chop off the female end, and chop off the male end on the GLI (the thing I linked above in #3), and solder the two together.
Re-mount the female end of the GLI to the face plate, and tuck away the additional hardware behind the stereo
Alternatively, you can solder the male 3.5mm jack to the GLI and run that as your 3.5mm cable.
The alternative way will give less interference as there's one less connection point, but it's not optimal as the 3.5mm cable may not be long enough.
Use shielded shrink tube on all connection points, and make sure that you wrap it in some EMI Shielding Tape for the best audio throughput. The EMI stuff is optional too.

Wow! Well it looks like I'm In trouble. As my car is a Toyota Prius classic which has a cassette deck. I use a cassette adapter to a female plug adapter to a thin male plug which fits through my case. Two adapter is one too many I would guess. Thanks for your time and input on what to do to fix this issue.
Every time I connect the headphones to the Nexus 6P start Google Voice, thus interrupting several times (every minute or so) what I'm listening: music from Play music, streaming radio from Chrome, etc ...
How can I solve this problem?
Thank you.

Audio static with aux cable

Hey so on some aux cables there's that horrible static constantly unless you turn on the audio upscaling, but this doesn't work for all apps such as when I get a phone call. Why is this issue happening in the first place? I was looking through forums and I saw a Galaxy S7 owner with the same issue. Why hasn't Samsung fixed this? This is unacceptable for a software correctable issue on a high end device.
I
Yeah I am having the same problem. This is unacceptable, I'm returning my phone tomorrow.
I just picked up my phone yesterday at BestBuy (At&t NEXT program)....While playing music, it's fine, but using Google Maps through my stereo, it's horrible (hisssss and static)! But, it only happens when I'm charging my phone at the same time?
I'm picking up a bluetooth adapter, with my $100 gift card I got for getting the phone, and going to try that tomorrow evening?
To the first two, you're likely using inferior quality Aux cables which is why you're only experiencing this issue on "some" cables as you state in your OP post.
To the last poster, this is just a simple ground loop interference. Its annoying but it happens to everyone if you're charging your phone while using the Aux for audio. Your solution is the right one, just get a decent BT 4.0 or higher adapter and you're set to go. Look for one with aptX support if possible for the best quality audio.
Anything analog cable and material matters a lot and for anything digital cables dont matter.
For example for SPDIF monster cable will be equal to a Chinese cable with same specs

LG G6 (870DS) DAC DoA?

Hello folks, got the G6 via mail today and everything was fine until I tried to enable the HiFi dac and then I was devastated.
It played music just fine then I switched on the hifi and it would pauce but instead of playing again it stops and all I get is a hissing noise with some weird dial up Internet sounds
Am I missing some box I was suppose to tick? I factory reset and it did not fix it. I feel it's a hardware issue and needs to replaced.. thoughts? What's wrong?
Here's a video of the problem: https://youtu.be/1Y62BTECLy8
All comments appreciated, thank you
i think you can not enable the dac while youre headpone is connected , you should first enable it and then when you connect your headphone it wil recognize the impedance and then the dac is automaticly enabled
hmmmm ... on low-impedance earbuds, it doesn't come on at all, although i can enable it and it does nothing. on high-impedance headphones it comes on automatically.
no the dac is made for 80 a 100 Ohm and higher offcoarse
I want to put your mind at ease. This happens to me sometimes. What kind of headphones are you using? If they don't have an in line mic then you can sometimes get some weird sound cutoffs with it. This has to do with the headphone jack being a "smart" headphone jack. The headphone jack has to detect impedance after all so it has to have some tech that won't be in your run of the mill headphone jack. Trying plugging in something with an in line mic just to verify and also you can trying jiggling and rotating in the jack with your current headphones a little bit.
This happens to me occasionally when I try to use aux cables in my car. It can get weird. It also sometimes interprets movement of the aux cable as pressing the pause button on an in line headphone mic controller etc. I wouldn't be worried about it until you troubleshoot this part.
Attach a 50 Ohm or higher headphone and the DAC will be available.
Headphone used is the ATH M50x
I got hope from your posts, went to a nearby store to try out the G6 they had with my headphone
Theirs had no problem playing with HiFi Dac enabled with the M50x, so it definitely is my units problem which sucks.
*Update*
Where I live, India, LG thankfully has a DoA program (10 days) where they replace it new at the service centre after a bit of formalities are done. Good news, I'll get a new replacement through them instead of shipping the phone to the original seller (with my money) and getting a new replacement from seller.
Just to double-check...
Guys,
I'm in the process of buying a smartphone mostly for the sound quality (so I can ditch my Nano), Wifi, screen, waterproofness and GPS functionality as I'm a semi-permanent traveller. I have expensive earbuds that I'm very happy with and that I'd like to keep, having compared them with 25+ (?) others. HOWEVER... Am I interpreting these messages correctly if I start thinking that with my 16 Ohm (@ 1kHz) finding any audiophile quality on a smartphone is just a pipe dream?? That would be terrible news...
