Add me to the dissatisfied new Nexus 7 owners who have this issue. I think the hiss is always there but at low volumes it almost sounds like there's some kind of filter trying to mute the speaker that is at its threshold and keeps turning on and off, which makes it more pronounced.
[Nexus 7 (2013) General] vanwel:
I think I can live with the noise when playing something, as most of the time I will have the volume up or using my headphones. But I cannot live with the activation of the speaker whenever I press a button... As I said before, volume at 0, when i press a button, the speaker gets activated, I hear a soft button press sound, and for a few seconds I hear static. After a few seconds the speaker turns of again. Its extremely annoying!

Is the GPS issue hardware related?
[Nexus 7 (2013) General] jasonchewy:
See how this is a problem with the design as many have pointed out on here.

Does anyone have a Nexus 7 2012 to compare?

Does the old Nexus 7 do the same?

I find it hard with so many "cheap" devices out there, that something from Google would have these kind of defect.

I mean playing anything audio, especially if it's originally low volume audio, the hiss is VERY noticeable.
[Nexus 7 (2013) General] habylab:
I read an article about it, something about it being necessary.

On my Galaxy s3, if I increase surround sound, static appears. Maybe that could be a basic reason?
[Nexus 7 (2013) General] WilliamG:
The quality control on the Nexus 7 is a joke. The actual device is so close to being really, truly great, but the quality control (and flawed design) hold it back. What am I referring to? Let me list my complaints - and I have TWO Nexus 7 2013 tablets.

1.) Far-too common to find dead/stuck pixels or dust under the glass.

2.) Multi-touch is simply broken on these devices. Some of them don't register, some of them don't register repeated taps, some register double-taps when you press just once.

3.) The static at low volume is simply a JOKE. An utter joke. It renders those nice stereo speakers pretty darn pointless unless you crank the volume enough to remove the static.

4.) Sleep/Awake sensor variances between devices. My wife's Nexus 7 won't consistently wake up if it's been sitting sleeping for any period of time, whereas mine does wake up - although sometimes it can take over a MINUTE to do so. A power-button press wakes it up instantly, though. What the heck is going on here?

5.) My current unit's microphone is broken. I have to yell into the hole on the right side of the device for it to hear me. My wife's - I can talk at normal volume and it works fine.

So it's obvious (to me at least) that the Nexus 7 could be such a good tablet, but it's utterly flawed in its current state, software-wise and hardware-wise.

It's a shame. And if it reads like I'm a pissed-off owner, it's because I am.
[Nexus 7 (2013) General] chriscosta77:
Yup, I've got that annoying static too. At least its the only flaw with mine.

Sent from my Nexus 7 FHD, 4.3 Stock, Rooted.
[Nexus 7 (2013) General] sladflob:
At risk of getting off-topic, I have to agree. The new N7 feels like a less mature device than last years, despite being thinner, lighter and having a better screen. I'm lucky enough not to have dust/pixel issues and my multi-touch seems fine so far, but this audio thing is really disappointing. What's the point of having better speakers if they have the annoying hiss?
[Nexus 7 (2013) General] Foggy79:
Is this problem already recognized by Google themselves?
[Nexus 7 (2013) General] twe69:
I know previous devices have had the same issue, for example my old HTC One had the same issue; am pretty sure my 2012 Nexus 7 will too but I hardly use the speakers as I am reading or browsing the internet; something that I can test out and reply back on.
[Nexus 7 (2013) General] WilliamG:
The HTC One (I owned one) also had the stupidest software glitch. It has stereo speakers, but the bottom speaker (when held portrait) is ALWAYS the right channel. So even when you rotate the device, the bottom speaker is always the right channel. I don't think this has ever been fixed. So stupid...
[Nexus 7 (2013) General] Oliv3:
This tablet could've been awesome if not for these ridiculous flaws.

First one had ghost touch issues, finally decided to return it after 3 weeks. However, now this second one has the same touch issues and now has this freaking static noise that the first one didn't.....

It's loud enough to be noticed every time the speakers turn on and off.

IMO a buggy touch interface and sound problems isn't something you should just shrug off and live with.

I suggest people who are experiencing these issues should just return it for a refund. Possibly purchasing it again down the line like 3-4 months from now, maybe Google will fix these issues....maybe...
[Nexus 7 (2013) General] WilliamG:
ALL Nexus 7 2013 have the static issue. So maybe you just never noticed it on the first one. But they all do it.
[Nexus 7 (2013) General] Sn00ky:
Same noise here. :( Also the speakers are not that louder than the 1st gen imo

Wondering if Asus would provide fixed speakers as a spare part a couple of months later and claim warranty replacement then. :)

What do you think, guys? Any chances?

edit: the last 4-5 clicks to the max volume don't seem that cumulative as the first 5 clicks.

It just does not increase the volume that much. Anyone with the same issue?
[Nexus 7 (2013) General] maconsultant:
I hope this is not an issue on the newly released LTE version.. I'll know soon enough.. It may be going back if its noticable.. My luck as it would be a sound issue as I have super strong ears..

[Nexus 7 (2013) General] DeDanMU:
I called the Google Play Service today. And the person i talked forwarded this problem. I hope i get a mail back soon.

to topic. It is very annoying. When you hearing music on Volume 1 to 3 the sough, rustle is louder then my music or a podcast for example.

Can you here the static sound when your device is doing something like playing a game (volume on zero)? The Sound comes from the upper speaker and it sounds like the working cpu or a fan. I think the N7 has no fan.
[Nexus 7 (2013) General] cognus:
I'm not trying to stir stuff up, just an honest question since you're in the know: I chunked Nexus 7 due to lousy audio, bought a ipad mini BECAUSE of superior audio.... at least it is "non-annoying" and can be very loud, especially with the right case/folio. my question is whether that device uses the op-amp you mention. thx.

this is discouraging because i had hoped that the audio issues of the prior gen Nexus 7 would be "all fixed" in the current

[p.s. my Galaxy Note 1 has superior audio to nex 7.... which really does not make sense to me but its a fact. one of the reasons why i hang onto the thing... that and the display format/ratio/perspective]
[Nexus 7 (2013) General] tni.andro:
The Original N7 had a really ****ty DAC. The N7 2013 DAC is pretty good, but the headphone amp sucks. I measured the output impedance at 38 Ohm.

So, if you use it as line out, it's fine, otherwise you better have some easy to drive headphones...
[Nexus 7 (2013) General] sladflob:
Watching a TED talk in bed this morning reminded me of how bad this issue really is. Speech with an otherwise quiet background seems to be the worst for hiss at all volumes. I'm really surprised that this problem hasn't received more exposure - either my ears are very sensitive (unlikely), I have a particularly bad device, or most users don't really care about audio quality.

Given that it only happens with the speakers, I can't help but wonder if it's got something to do with the surround sound processing. Are there any ROMs/kernels that let you turn this off so I can test this theory?
[Nexus 7 (2013) General] myepicyear:
There's actually a desktop heatsink-fan in the new N7. It's one of the key features they advertised. :D

Back speaker noise on new Nexus 7 (2013) on low volume

---------- Post added at 05:38 PM ---------- Previous post was at 05:23 PM ----------

Listen sample on GoHear
[Nexus 7 (2013) General] Richieboy67:
I still do not have this issue and find it funny that some were saying every new 7 had this. I do not hear anything abnormal when volume is low though I usually use volume loud enough to hear decently. I have tested though for this issue after update and no problem.

You really think it is the cpu interfering with sound? That seems unlikely. I would think maybe a bad ground or a lack of shielding.

---------- Post added at 08:13 PM ---------- Previous post was at 08:11 PM ----------

Is this supposed to be helpful? Scrub this please. :D

Seriously though, how low do you have to have the volume to hear this? Do you hear it at all without any volume if you hold close?
[Nexus 7 (2013) General] scandiun:
With the volume totally off is almost not noticeable, but when you put it at the bare minimum that you can hear, there's a big increase in noise there. Listen to my sample in GoHear where I'm at the bare minimum.

Does anybody know if the iPad/iPhone have the analog amplifier of use the same system than the Nexus 7 2013?
[Nexus 7 (2013) General] nashi20002003:
I have this issue too.does not bother me.
[Nexus 7 (2013) General] Unfussy:
Same here, starting when i get below 40% or so. Headphone plug seems fine so I'm not to troubled by it... Took me one week to notice anyway:p
[Nexus 7 (2013) General] scandiun:
I'll answer to myself: the iPad doesn't have this issue at all. Good job for Apple. The Nexus 7 was returned to Google.
[Nexus 7 (2013) General] Richieboy67:
What did this have to do with the IPad? My motorcycle doesn't cook fried chicken.. So what. Irrelevant..

And doubtful they share the same amp.
[Nexus 7 (2013) General] scandiun:
It's a comparison. Not even if the speaker is the same, but rather its technology.
[Nexus 7 (2013) General] i486:
I think that the problem relies in the heavily unbalanced gain applied by the post processing of the audio by the surround software.

I tried several sources of audio, such as games, videos/music and VoIP calls, and while the noise was clear on some it was inexistent on others. At the same time I played with the equalizer of Google's player app and noted much less noise on the ones that had it.

That leads me to conclude that there is some software problem such as bad adjustment of the gain on some high frequencies(resulting in the above average noise amplification).
[Nexus 7 (2013) General] iHOX:
Are there some news about this? Are there any new devices without this problem?
[Nexus 7 (2013) General] Jagutherrschaften:

[Nexus 7 (2013) General] inkogneetoe:
I'm on my 3rd device in the UK and it's still the same, I've also got the pop when I play a paused video audio clip. didn't notice this in the last 2 devices but I'm nearly sure it has only happened since the last update. I'm stock unrooted on the 3 devices.

Not sure what I'm going to do, bare with it or refund

Edit: So after a bit of a play around the pop I'm getting is only coming from the top speaker. Guess device 4 for me to fix that issue :( Maybe I'll just buy the Tesco tab.... probably no sound issues with that. This is my second Asus tab,had the infinity, not impressed with them or Google
[Nexus 7 (2013) General] nickj2010:
I personally fixed my low speaker static by using a kernel with Faux sound enabled and using that to set the speaker gain to about -5, this results in being able to use a higher volume level which doesn't have static present, but the device is still quiet enough to watch videos in bed.
[Nexus 7 (2013) General] scandiun:
Which kernel did you use?
[Nexus 7 (2013) General] nickj2010:
Personally used elementalx, faux kernel has it as well, not sure about any other nexus7 kernels.

You will need either Faux sound app or trickster donate to edit the numbers.
[Nexus 7 (2013) General] Skyrocket2Paradise:
this definitely helps
[Nexus 7 (2013) General] inkogneetoe:

This exists, a simple way to find it is to mute then play some music you'll hear the static noise. It didn't bother me much as I mainly use a earpod.
[Nexus 7 (2013) General] Dennis Zhu:
I'm OK with the sound
[Nexus 7 (2013) General] Ashin:
Can someone explain why it still has static when sound is muted?

Surely it is wasting power... it's as if the speaker is never actually turned off, but the volume is just set super low.
[Nexus 7 (2013) General] denial512:
So anyone confirm that running a custom kernel, and changing the audio settings with that fixes this issue?

Does it fix it, or does it lessen it?

Which kernel exactly? I can't seem to find any custom kernels for 4.4?

A quick guide for fixing it by this manner would be great!
[Nexus 7 (2013) General] shaevy:
It doesnt fix it, it just gets less annoying. 4.4 kernels will be coming in after Google releases kernel sources.

I now have my second unit, first was returned by me because, mainly, this sound issues. Also the multitouch was not in perfect condition, but how is going to use ten fingers at same time?

This second unit have the same problem, even worse.

It's a shame Asus/Google produce a Tablet with this sound issues.

In night, at my room, putting the sound to the slowest, or second slowest sound level is simple horrible.

As of today I have more 20 days until I can return the Tablet, the Tablet just have to stay in perfect condition.

So Asus/Google I'm willing to return the units about in each 30 days. No problem.

Maybe some day I got one in perfect condition, how knows? Let's hope! Or will pass 1 year and I exchange this for the 2014 version, :good:

Very annoying. I updated to Kit Kat and now experience this static buzzing low sound now. It was fine on 4.3!
[Nexus 7 (2013) General] inkogneetoe:
100% Sure it was fine on 4.3? Of that's the case it must be something in the software or just coincidence
[Nexus 7 (2013) General] itasoulas:
i was playing angry birds today and the static sound was there. I noticed that when I lowered the volume. If it's not a hardware issue then the answer is hidden somewhere on the system/lib/hw folder, maybe audio.policy or audio.primary .so files. Maybe some coding error/conflict or someone maxed out the speakers volume beyond standards? I will contact a friend here on XDA and see if he can help us about this. IF of course this is a software issue...
[Nexus 7 (2013) General] Matrix_19:
It was not fine on 4.3

It's a hardware issue on all nexus 7
[Nexus 7 (2013) General] Tim4:
Someone explained that before, the reason of noise is volume control too aggressive on nexus 7, RMA wouldnt help.
[Nexus 7 (2013) General] e93dave:
It was fine for me. I play a lot of clash of clans in bed at night at minimum volume. Unless the static buzzing noise was A LOT quieter in 4.3. Kit Kat made it just completely unbearable now.

Very disappointing but quite happy with the kit kat performance, battery life and touch screen improvements
[Nexus 7 (2013) General] inkogneetoe:
I know that so it's gone for "repair" mainly to see what reason they give if it's unfixable. I've yet to hear anyone on here having sent their device for repair. Lots of moaning... No action!!
[Nexus 7 (2013) General] habylab:
Now instead of a static sound, of sounds like a high-pitched whirring sound, almost like I can hear the device working, every time I touch the device, even with the sound off.
[Nexus 7 (2013) General] shaevy:
In Addition to the rather loud buzzing noise(from the speakers) when listening to silent music I also hear a really silent high pitch noise that is only present when the screen backlight is on. Its kind of like a coil whine.

It's present in all units because is just the quality of the speaker, and if it is not the speaker the isolation quality... so it wasn't better in 4.3.

[Nexus 7 (2013) General] matthewr87:
Interestingly enough my speaker static at low volumes has noticeable improved after this update...
[Nexus 7 (2013) General] AthlonBoy:
Wrong.

I've only had this noise since updating to 4.4. Until then I was on JWR66N because of a SuperSU bug with regards to OTAs and an unwillingness to flash a new ROM over it. Now I'm on KRT16S and AUGH MY EARS

I could listen to anything you threw at me, even at minimum volume, and not get a hint of noise. It was impeccably clear. Now, voices are clipped so badly as to be incomprehensible. This is absolutely a software problem. The sooner this gets accepted, the sooner we can fix it. Until then, I'll try a kernel tweak.
[Nexus 7 (2013) General] Matrix_19:
4.4.1 makes this a lot better for me !

the noise is not completely gone , but definitely less audible after this update
[Nexus 7 (2013) General] inkogneetoe:
Got mine back from Asus repair. They changed the main board. Still the same. They obviously acknowledged the defect to perform a repair but no change.

It also came back with damage on it around the edges, looks like damage while separating the screen and casing.

I'm happy to report that on 4.4.2 (probably also 4.4.1) I consider the issue solved.

I've just sideloaded the 4.4.2 update on my Nexus 2013 WiFi.

I've used this video for the test:

http://www.youtube.com/watch?v=kpqBNn_BfKE

It's MKBHD's Hangout with Motorola CEO Dennis Woodside.

I chose this video because the quality of the mics he is using is very good, there is almost no noise generated from them.

I've listened the same video on my HTC One X which has better speakers hardware vise.

You can still here the noise from the Nexus 7 speakers but now the noise is not mixing with the actual sound from the video and you can clearly understand e.g. speech on volume as low as one. Of course to hear the actual noise now you have to stick your ear close to the speakers and be in the silent room.

Thanks Google for fixing it.

I think this is the best we can get and I'm satisfied.

I'm just not happy that Google didn't acknowledge this as a bug in the first place so that we at least could had hope for a fix.
[Nexus 7 (2013) General] xIJTIx:
I don't think the issue was fixed. I was playing a game which I muster the sound(in the game not the device) and I can hear the buzzing from the speakers which can get annoying after while. I also noticed that when any sound is played, for example the sound from Hitting the home key, you also hear the buzzing for a second or so and it stops. at least that is how it is on my device. I'm only just noticing it now though. Not sure if it is because of 4.4.2 or I was just never close enough to hear it until now.
[Nexus 7 (2013) General] vbaros:
What are you describing is something else and it is a hardware fault.

I've heard other people complaining about the same thing.
[Nexus 7 (2013) General] xIJTIx:
Can you point me in that direction? I ended up here looking into my problem so now seems I might need to RMA it.
[Nexus 7 (2013) General] vbaros:
Your best bet is to RMA unfortunately :(
[Nexus 7 (2013) General] rbross3030:
I too can hear the same sound you describe under the same circumstances but it is very faint and only emits from the top speaker (the one closest to the camera). It is far less noticeable than the hiss that this thread primarily was focusing on though (fixed for me with 4.4.2 as well), you really need to be in a quiet room to hear it. Am I to understand that some or most of you hear absolutely no momentary buzz at all from the top speaker after locking your device (after the lock 'click' sound plays)? I can actually hear something very similar to this through my headphones when they are connected to my ****Book Pro, like something isn't grounded properly and is causing analog interference with the audio out...
[Nexus 7 (2013) General] hughlle:
My tablet updates to 4.2.2 last night. Since then my speakers squeal and fuzz at any volume, even when no audio is played, and even on silent.

Prior to the update it was absolutely fine.
