Ok, here is what I found out. I did unroot teh devide and reset it to factory. To wrap my findings up:
I connected my Nexus 7 to my AV Receiver and Speakers.
1) When playing Music all is fine - no humming / buzzing / cracking!
2) WhenMUSIC IS OFF, but SCREEN IS ON you can start hearing a buzzing ( which I could live with as I know analogue sources do sometimes have that buzzing, although none of my other devices such as the Galaxy S4 has it)
3) THIS IS NOT ACCEPTABLE! Whenever the Screen turns off I get a high pitched buzzing that could potentially ruin my speakers!
Can anyone confirm this or help me out here?

Hello guys, i have a random problem. I have my nexus connected to external speakers and only when idle I hear weird crackling noise, when playing music or going through menu and such it almost disappears.
I have my nexus connected via aux cable. It is really bad that cracking noise.its not like a smooth humming that u can expect from analog sources. It gets also high pitched etc and I'm afraid to break my speakers once it goes idle.
Is my device faulty?
BTW with headphones attached I don't really get it much.

I might suggest you try using a ferrite core and see if that helps.

One of these: http://www.thatcable.com/product/7mm-Clip-On-Ferrite-Core (you can find them cheaper, this was only for example) it reduces click and whine, they are cheap enough so if it doesn't work it's no big deal.
But why does it happen when idle? Do you get any noise, Crack, anything when u hock it up to a receiver, external speakers?

Do you want an explanation or a fix? I am telling you of a possible fix, I would have to do a site survey, and test the equipment with various pieces of equipment to accurately determine the why.
No, I don't hook my tablet up to my equipment, they are capable of playing all my music without the aid of my tablet, the suggestion I made was to correct noise which can be caused by grounding or external RF, buy the core, or don't buy the core, it's all the same to me, I'm just trying to help you out here.
I'm very thankful. But nevertheless it would be interesting to see if others experience the same. I'll order it anyway thanks.

I use an older phone (Droid RAZR Maxx) that is connected to my home stereo for Pandora, Google Music, etc and yes, I have the loud crackling noise. Actually, I should say I had the noise. I used a different device, called a ground loop isolator. I would assume it serves a similar purpose as the core, to simply reduce grounding noise. They are cheap on amazon or newegg or something.
I think this actually the exact one I have:
http://www.amazon.com/PAC-Ground-Is...92235085&sr=1-1&keywords=ground+loop+isolator
The other day I plugged my N7 to my Logitech Z323 speakers and I had blank noise aswell during idle.
It would fade into the music as soon as music played louder than the noise itself but it was still there.
What I did was a bit random but it worked and I believe the noise is caused by the lack of grouding.
Plugged the N7 to my speakers (the Z323 speakers have 2 extra aux slots) with an aux cable and then plugged the speakers to my computer through their own aux cable. This created grouding and the noise disapeared.
Was it really just a blank constant noise? If it was just that fine I could live with it. But this noise I'm experiencing is not smooth it gets high pitched too etc. Not a stable humming.
I plugged mine into an av receiver, only Nr 414.
When I'm back home I'll record a video for u to see.
By the way I rooted my device. But I doubt that has anything to do with it?
Gesendet von meinem GT-I9505 mit Tapatalk
My device is also rooted but I doubt it has anything to do with it.
In my case, the sound was similar to when you don't properly plug the aux cable hence why, plugging the speakers a second time, onto my computer fixed the issue.

I dont get what u mean with pluggin in a second time? I only want to connect my N7 with my av receiver. Are you saying that pluggin in the cable from the AV Receiver into the Laptop and then pluggin in the N7 afterwards helped?
Please verify once more, have u connected to a AV Receiver, or just some Speakers?

This is what I did.
I know it's not exactly the same thing but I bet the cause is the same.
i have my nexus hard wired to my car. using the headphone jack, i can hear all kinds noise when booting up. during playback there are no issues, but once i pause or stop playback, the DAC seems to go to sleep mode, then i can hear some noise again. ofcourse, its not as loud as noise i hear during bootup, but still annoying.
i switched to using the behringer uca 202 usb dac with an otg cable, and all problems went away. also audio quality became definitely much better.

It seems like a grounding issue in your car or you need a better shielded wire. Just my opinion for what ever that is worth.

well yes its a headphone jack and its quite a premium cable nothing cheap. ive tested many devices plugged in via aux calble.. galaxy s4, lg phone, iphone 4 / 5 - NONE of them had these issues.
Its quite bad that in order for me to play music from my nexus i need to buy extra stuff dont u think?

when i plug my phone into my car to play music its fine. when i use my car charger and play music at the same time tis fine but the second the music stop i hear a static noise from my speakers (which is attached to my galaxy)
this static noise is an imitation of whatever my car is doing at that moment (if im reving the engine the static will resemble the revs, same with turn signals)
anyone else experiencing this problem?
It's feedback from the car electrical system. Usually a bad alternator ground or corroded battery cables, or even the cables going to the starter.

I'm assuming it isn't a stock deck? Check your ground and of possible try a new location.
All in all though, Androids micro USB is a horrible horrible connection. Every Android phone I have ever owned makes some sort of hissing sound while charging and listening to audio through the headphone jack. Even the Google Nexus does. But the iphone doesn't. Go figure.

On my i747m, I could not use the USB port to listen to music while I was charging via cigarette lighter. There is a definite design flaw. I bought an Ibolt dock and am not able to use it the way it is intended. Even when I wired it myself from scratch (I'm a sound tech) it failed.
Not only does it make white noise and static between songs, but there is some kind of GATE that kicks in 1 or 2 secs after any music pause....it cuts the noise in half but it still remains...and the act of cutting, is an irritant in itself. Further more, even when your playing music, the NOISE is fighting for sonic real estate. I can hear it. I am trained.
So for me, I am running the audio out of the headphone jack. It's 98% better but still not 100%. I don't get the classic REV issue...which has to do with grounding and/or cable shielding. But, if I was you, I would go to The Source store and pick up a Ground Isolator. They have one specific for car issues like yours.
Its a ground loop.

It MIGHT... be a ground loop.
It might NOT.
Read my post #7.
If your using USB audio, there is an internal design flaw NOISE issue independent from any GROUND issues. (at least with my i747m) I can reproduce the machine like noise in the car, on a desk dock, on a separate stereo system. The Ground Loop isolator did not help my issue but it's worth trying if you get the hum/car interference noise from usb and/or headphones.
Hi Everyone,
my headphone jack is broken. It does not recognize anymore if I plug in a headphone. Besides that I always had problems with the sound coming out of the headphones. It was distorted. And when I used some headphones with a microphone, people complained that they do not hear me.
So my questions are: Does anyone encounter the same problem? Does anyone have any suggestions how I might fix that? I think it is a Hardware issue but could it be a software issue, too?
Thanks
Stupid suggestion, but have you tried to reboot?

yes I did. It seems to be a hardware issue since it is getting worse every day. I sent my phone to the fairphone support team. They told me that if their technician thinks, that it is not a factory fault, it costs 160€ to repair it.
Since it worked in the beginning I am curious how they figure out if it was a factory fault. And other than that. I didn't use the headphone jack any different than on my last (samsung) phone. I never had problems with that. And even IF they tell me that it is my fault the headphone jack broke, I feel like even with an "uncorrect" usage of the headphone jack (however you could "miss-use" the headphone jack) the phone should last more than 2 month.
So I am curious on how this works out. But since I have the bluetooth issue, the hypersensitive screen issue and the headphone jack issue, I am wondering if it is worth paying 160€ to just fix ONE of those problems.
just to give an small update (for the sake of documentation):
I received an E-Mail today:
Your phone is as good as new and ready for you! We are sending your package out today.

I sent my fairphone in on Monday, it took 4 days until it arrived AND they fixed it. I think that this is quite good. Hope that it works now (I will report back if it does not). And I hope that the new update fixes my bluetooth issues with my car.
Then the only thing which is annoying to me is my hypersensitve screen.
Hi,
I had also an issue with the headphone jack.
The button of the headset wasn't working unless i had put a lot of pressure on the connector.
But even then, it was unstable.
I think the soldering was faulty.
I was about to have it repaired but sadly i had other issues (GPS & Blutooth) as well and couldn't keep the phone
I sent it back to Fairphone and they gave me a refund :good:
hello there,
i have a similar problem, only that i think it is not just the jack but it ha to have something to do with the software as well, as the headset is working super when i'm doing a skype call. with normal call though it drives me absolutely bonkers!!!!!!!! in 70% of all cases they partner doesn't understand me. i have tried i don't know how many headsets. it has to be the software so what to do????
Hi,
I've got a very strange and annoying problem. I've got a Nexus 5X and a 2008 BMW Z4 3.0si Roadster with a removable 3.5mm audio cable.
I've tried my Nexus 5X with 3 different cable on a lot of other car, hifi stereo and earphone and it always works (the sound go to the other device the way it should work).
I've tried 5 different phones on my BMW and the sound go to the Z4 speaker the right way.
But when I try to connect my Nexus to the BMW 9 times out of 10 the phone doesn't recognize it and continue to play the sound on the phone speakers. The strangest thing is after that half the time when I remove the cable from the car but keep it on the phone it recognize the cable and stop playing music on phone speakers. At this time I can connect it again to my BMW and then the sound go to the car speaker.
I can't understand anything about this problem and it's driving me a little bit crazy. Sadly no Bluetooth on my lovely Z4.
Anyone as an idea ?
Thank

Did you try pressing really hard on the plug? It is a very tight fit to the point you feel like you might be breaking the port, but it loosens over time.

The reason I ask is it still works if not plugged in all the way, just the connection is not that reliable. Quite a few people though they had it plugged in all the way and they were getting sound, but sometimes sound would switch back to the phone. It turned out they really needed to push in the cable really hard.
Does it work if you start the music after plugging in the phone? That's how I have to do it in my POS Dodge work truck.

Nope and it makes no change if I plug it before or after the music start playing.

So I've been using my tablet in the car to watch Netflix and Amazon Prime videos during various appointments for my wife and kids. Has worked great with headphones, but figured it would be even better with my car's audio system. So I ordered a decent quality aux cable off Amazon, a 2-pack actually, but it doesn't work! I get really heavy static with the audio barely audible in the background. It also only plays out of the left channel. Tried the other cable with the same result. Plugged that cable into my Galaxy S9 and it worked perfectly.
I've searched around for the past half hour with no luck. Seems some fixed similar issues with other Samsung devices by turning on the UHQ upscaler, or by holding Vol+ while cycling the power, but neither worked for me.
Any thoughts?

Sounds like a faulty jack have you tried twisting the jack ? As sometimes that clears the static ? if not then you will need to get your Tab S4 replaced via Samsung!
I did rotate the plug, but it didn't resolve the issue. I don't think the jack is faulty, though, since headphones work perfectly. Thank you for your response, though.

I may be totally off but...
I have been using an MP3 player (Archos Jukebox Recorder) in my car for years. Recently I thought to go modern and downloaded some music on my Samsung A3 (2017) phone. Connected the cable... and all I got was a lot of static noise with hardly audible (and bearable) music.
Of course, the MP3 player using the same cable still plays ok. Anything plugged into the A3 also plays fine.
I haven't yet sorted out what could have been the problem but it sounds awfully like yours.
Sure does!

Cables make a huge difference getting a cheaper cable often out preforms the pricey one! (That's no joke) Disconnecting the FM/AM radio cable gets rid of the static (Here in the UK that has done trick in the past) Also can you try switching over the plugs on the back of your head unit right into left, and left into right. Vice versa see if that fix it ?

Switched the cable and the static seems gone... Strange that the Archos didn't have this problem. But I needed to increase the volume to a surprisingly high level[*] to get a decent sound.

To be able to charge at the same time, you will need active headphones instead of passive which means an extra soundcard that will pull energy from the battery. As passive headphones when detected changes the USB + and - to connect the headphones to the internal soundcard/DSP-board and if you also insert 5v at the same time would probably fry the DSP-chip. [emoji38]
I'm using a USB active splitter and an old 3.5mm headphone so I can charge at the same time, it works but I do get worse sound quality and also lower sound levels this way. Best solution is a good bluetooth 5 headset, then you both get good sound and can charge the phone.

I tried a USB active splitter with a regular pair of 3.5mm headphones. Audio quality was okay, not impressive at all, but using them for phone calls......horrible. I could hear the person I'm talking to, but they would claim they couldn't hear me or I sounded far away. I'm not big on Bluetooth headsets. Especially now considering most of them come with 2 earbuds. I prefer a single earbud. Maybe I'll have to look on Amazon again and see if theirs anything new.
USB-C pixel buds are great. Had them for around 8 months now and no issues.
If you are looking for a set that have the ear tips then probably best going with the USB-C bullets. Great sound but I don't use them anymore because I prefer a set that don't go deep into my ear
