[Q] Tegra K1 chip making noise - Shield Tablet Q&A, Help & Troubleshooting

Last night I was using my shield tablet and I heard a noise when I touched the screen...thought it might be the speakers so I turned them down and could still hear it, so I put my ear to back of tablet and can hear buzzing when the screen is touched or when an app is running, and it I play a high graphic game its pretty loud.
Is this normal sound of the K1 processor? Anyone else had this before? Wanna know do I need to return it or not!
Thanks

Same here.

I'm curious about this too. I also thought it was speaker buzz but it's not.

Guess no one helps here...found this though.... forums.geforce.com/default/topic/785841/shield-tablet/noise-near-from-the-speaker-opposite-side-from-hdmi-/
Seems like its normal to hear the processor and nothing to worry about!

been reading about this and couldn't stop until i found a satisfactory answer, so i kept digging and found this :
" This 'whine' or 'squeal' is the sound of these things ( inductors, coils or chokes ) physically vibrating, and it is a sign that they are poorly insulated. However this does not mean they have a shorter lifespan than a coil that does not whine and you really shouldn't lose sleep over it.
Why do they only whine when the PC is under load? What you're hearing is an effect of the PWM frequency, and as you pull more current through the inductor it induces a greater magnetic field in itself and in turn vibrating more aggressively.
Will it go away? Well, Possibly. My 8800GT squealed like a piglet in a housefire for months, and one day the noise disappeared completely. Either some characteristics of the circuit had changed or the windings in the coil had shifted.
Can you stop it? As most people know, you can stop inductors whining by chucking hot glue at them, putting high voltage putty around them, or soaking them in resin and waiting for them to set. Most (apart from PSU) inductors in PCs are covered anyway, so you can't properly silence them.
"

[Q] High Pitch Whine While In Dock?

Is anyone else experiencing a high pitch whine while docked? It only happens when the Transformer is docked.
I noticed this the other day, and if I put my ear close to the dock it seems as though the high pitched sound is coming from the charging port on the dock. I wonder if maybe this has something to do with my extensive battery loss while having it docked. Is this a widepsread issue that others have also noticed?
mine is silent in or out of the dock. A blessed relief as my laptop always gave off a high pitched whine.

Yeah that's exactly what I'm thinking.
Anyone else having this issue?
My dock is silent.
My dock is silent also.
I have my ear to the TF in the dock and don't hear a thing.
So when you guys have your tablet docked into the keyboard and you put your ear up to the pin connect on the keyboard you aren't hearing a high pitched whine?

I could be an age issue. After about 20 you start losing higher frequency hearing. Store around here that don't want kids hanging around use speakers that broadcast annoying tones in these higher frequencies.
I'm 19 and no whine.
I'm 22 and hear the whine. When I undock the tablet it stops, but as soon as I dock it in the whine comes from the pin connector, almost like power is exiting from the pin connector....not the most technical term and I have no idea what I am talking about, but that would be my guess lol.
Mine whines and the dock battery seems to drain excessively.
This thread will quickly turn into, "How old are you? Haha, you have to deal with the whine for a few more years, suckerr"
If the whine is persistent, swap it. To me, that would be unbearably annoying.

Would try to if I could even get in touch with Asus Support. Weeks and they haven't responded to either of my Technical Support inquiries.
I don't have the dock yet but my TF101 charger makes a whine/buzz sound if you are in a really quiet room.
My dock is emitting the anoying sound. Can hear it pretty clearly
My first Transformer had a prductionfault in top of the panel with some glue all over, no sound and no wifi antenna working.
This one have this ****ty sound and an edge bleed in the down left corners (Picture)
This is really ****ty by ASUS.

mine makes awful high pitch noise as well.
for some reason it started doing that and now the battery gets warm too. I am sensitive to those kind of noises and drives me crazy. i have to call asus for resolution. this sucks, i got it for christmas not even a month old and is defective, by the way the left usp port does not work for some reason. i love my table thought, just with i would wish the keyboard works, anyone else has this problem with a possible resolution.
There shouldn't be any noise at all, considering there's no moving parts whatsoever.

Is it safe to...

I was wondering if anyone charges or tethers their phone by the USB port on the dock. And if u have any issues doing so. I tried and I can hear an odd whiny buzz sound from the connection. It would be nice to do as long as I am not going to fry it. So if you have been doing this without problems for awhile plz drop a line about ur experience.
I am tethering my EVO 4G to charge the battery. Haven't noticed any buzzing. Using WiFi Tether for the Internet.

The sound is extremely quiet. I have to put my ear close to hear it clearly.

If that's the case I wouldn't worry too much. If it was loud enough to be heard from a distance, or over ambient noise then I would take a closer look at it. Electronics does make all sorts of noises (think of the old flyback transformers in televisions before they became all solid-state), especially if considerable current is going through it. Also flyback transformers are still used but on a smaller scale in switching power supplies. They generally operate in the 15-22kHz range. I bet you're a very young person since most people by time they hit their mid-20's lose the high-end of their hearing due to normal aging (faster if they listen to loud music/attend concerts like I did).

Speaker Issue?

So i'll be casully playing Modern Combat 5 with my controller when suddenly this weird screeching type noise will come out of the speakers, it lasts for a second then stops although one time it seemed to just keep doing it over and over. It's not part of the game for sure and although I have the increased volume mod this was happening even before i rooted. Anyone else getting this?

Hi.
Also got this when playing Asphalt 8. Its only sometimes when the game is loading.
And its not the same as the static scream that occurs on custom roms like Pac Man.
Thanks

So it seems to be only with Gameloft games?
Hi, bought the tablet last week, noticed some kind of slight buzzing noise coming from the speakers when playing games. Even when I put the sound off.
It's like the CPU is working and you get interference from the speakers.
Spoke with NVIDIA customer service and they suggested trying connecting headphones to test. Did so, and although from the headphones the sound was fine, the speakers still had this slight noise.
Anyone else experiencing similar thing?

Were you plugged in charging the device? To my understanding sometimes that causes the slight buzz.

I think it's a sound driver issue. I've had it happen on other devices when trying to use Viper4Android. I am hoping they address it in the lollipop update.

No, so far I have only used the tablet while discharging. It's very strange how much it varies sometimes; when I played Skylanders (free) it was quite intense. With other games it's not very noticable

I just returned my for a refund due to static popping when using a headset. even with the volume muted i heard he sound. called Nvidia and they are aware that some devices have that defect. I decided to wait and try the nexus 9 if i don't like It I will try the shield again.

Im gettingnthe same thing in Youtube, I hope they fix it.
Same here.
Heard the screach/buzz sound first time when playing Zombie Driver (tablet even turned off afterwards) then later several times in YouTube.
Looks like HW problem to me.
I get a screech of sorts every now and then, even outside of apps, when system sounds and notifications are triggered. Like a lot of other things on the tablet, it might be a hardware issue, but it might be software- I know that I didn't get any before the recent OTA.
When I touch my display I get some static noise on the side speakers, sounds are similar to a hard drive writing, its rather quiet but you can hear it and it sure is annoying!

Same thing happens to me, but i can only hear it in a dead quiet room. I find it tends to mostly go away if you put the power settings in 'battery saver'. My guess would it be some kind of interference from the proc and the audio processor when all the cores are running... not sure if it is just a general hardware thing or perhaps something that can be fixed in the audio driver.
I just had a similar issue, although mine was while playing Hearthstone and was insanely loud! It sounded like a fire drill, and I'm not exaggerating. It wouldn't stop either, like it has in the past, and I had to force shut down the tablet. I'm kind of wishing I would have waited a little longer to buy or waited for the next version to come out. I contacted Nvidia support and they basically gave me the run-around and all they said was that I should send them a video! Seriously??? Like I had the forethought to take a video while my tablet was screaming at me. I guess that's how much Nvidia cares, and I'll be sure to have my camera ready for the next time the SHIELD goes into fire drill mode.

How could they understand what happens if your device freezes when it outputs this sound or gives no usable log to diagnose it, and if you cannot reproduce it easily ? the video request is not so silly... Do you have experienced this just once ?

Well a video is not going to help them any more either now is it? That won't produce logs or outputs, unless you know something i don't. What they should have done is let me ship it back to them, send Me a replacement and run their own diagnostics on it to understand it better... That's what Amazon would do, and this is why they are not selling better. Make sense?
At least if they have a video they will have a clue if they know this issue, if your tablet freezes or not, and try to reproduce it (they won't try for a month to test a game, when maybe there is a software bug on a certain level in it, or whatever else, and maybe this is not hardware related). Nvidia is not responsible for OS instability. At least with a video they'll know it's not a random "one time" crash.
If it was my tablet, I would do a backup, factory reset, install just this one game, and see if there's still a problem.
Of course you can try to convince them to RMA your device, it's not your task to repair it. Good luck.
I had this happen to me yesterday(and couple times before too). Woke the tablet up after about 10 hrs or so and it was dead slow. I tap on something and it takes about 5 seconds for the tablet to register the touch and launch the app. It was during this time that the screeching noise came. And it happened a couple of times as I tried to get this thing to respond to my touches.
Finally had to restart it and it was back to being the zippy tablet that its supposed to be
About the video, i think thats a great idea, since that will at least give an idea about the sound. I dont know how to explain the sound either. Its like a metallic grinding noise, which is pretty scary because I feel like the fricking tablet is about to explode or something.
noise is going up and down, but always there
Same problem here.. Buzzing from booth speakers and at the back of the tablet. Weird thing is I can't open the faceworks app.. Gives me shader erroror something. Something wrong with GPU? Or is it lollipop update that has screwed with the tab? Since I can't see many older posts about this I mean.
almost every shield tablet makes that noise. its annoying but nothing wrong with it, its just poor electric shielding which causes interferences with the speakers.
Do you guys experience a slow down or lag when the sound comes on? I mean other than @crazyjc81.
I suspect it is related to the general lag issues that are going around. Ex. Sound is sent to the speakers and then it lags so the sound just keeps going until the processor gets around to turning it off.

[Q] Quiet Hissing/Electrical buzzing from tablet?

Hey guys, does anyone else experience some quiet continuous popping and electrical sounds coming from inside the back of the tablet? If I put my ear on the back, it pretty much sounds like continuous popping and something like a laptop HDD running.
It's not that bad but gets noticeable in a quiet room especially on tegra apps, even dabbler.
I know it has a desktop GPU chip inside and I know this is common in desktop video cards but is this normal on this tablet?

I've got the same thing.
The tablet had fan cooling system inside I believe.

Hissing mechanical noise during load...
I too have noticed this on my lte unit first night use.
I might be talking about something else, although regarding the hissing noise similar to harddrive (i dont really get the popping noise, nowhere near loud PoP sounds)
I can relate this noise very similar experience ive had on my computer with low level (in anotherwords cheap) onboard sound card -chip. Board was made by intel for dell. Basically it did the very close, in moments when hdd&ram cooperated in that computer under high cpu load, this sound came from the computers speakers.
Im surprised shield brings me back to the times 5 years earlier, i could hear it just now. Its random, but nothing i would be concerned of. Theres no point of rma this since its more of us noticing, i guess all the shield tablets produce this electric-static noise, speakers are pretty neat so maybe it was harder to hide imperfection of nvidias sound solution?
More accurate to confirm would be to know other tablets that use the same sound processor vs above mention hissing mechanical sound.
I can only hear it at night though, and frankly, it is loud but it still keeps me happy. My old oem pc was worse, it hissed even by moving the mouse around, it was so bad you could count dpi with closed eyes! Now that's what i call disturbing :laugh:

To me it sounds more like a voltage conversion-related sound like many power adapters make (including the Shield's) when under load. My power strip will also produce that sound if you plug high-power devices straight into its USB ports (I wish I knew the amperage on those ports).
EDIT: I have heard this sound on occasion myself is what I mean by this, and it doesn't sound like old "speaker squeaking" I've observed on older computers. I HAVE heard it on some laptops.
Thanks a lot for the feedback guys, i just wanted to know if there's something wrong with my tablet or it's something everyone gets. Anyway, i've also noticed some hissing when scrolling in Chrome. Not sure if it's the speakers or internal components hissing but it's not that big of a deal.

[Q] Anyone have a very quiet speaker crackle?

Got my Shield Tablet a week ago, really enjoying it so far.
However, I've noticed when I settle in the for evenings I can hear a very faint speaker crackle coming from the lower speaker but can still be heard out of the upper one. Its super faint.
I don't know if its when its connected to its charger, or if its happening all the time but I can only hear it in a silent room. I'll check and report back tonight but if anyone else has experienced this, I'd love to know.
Many thanks
I have heard it as well. My hearing has always been sensitive enough I can hear the old CRT TVs when they are on, and even heard the color wheel of an old projection TV going before it finally quit. This is in the same frequency as those things.
I hear a static sound randomly from the speakers and I have not pinned down the cause as it happens at rest and very active times. I believe some of this might be from the heatsink from previous items I have read about.
The second item is the high pitched whine which I hear connected to my S4 power charger. Again, intermittent there, it does not always make the sound, but it does make it often enough that it is not rare.
I only hear the whine on the charger, but I never hear the whine off the charger.
I sometimes hear both the static/crackle and the whine sometimes, so the whine may be from something in the charging process.
Sorry, I know not much information, but more of a vote that you aren't hearing things and some experiences I have had so far.

I really appreciate your reply thank you, at least I know it's not just me.
I'm just trying to figure out if I should RMA it or not. Sat in bed typing this and the noise is there until the display is off. Doesn't matter if it's on charge or not. Odd though as I haven't heard it all day.
It almost sounds like a very small short in a speaker somewhere.
Thanks again.
It's common to the Shield. I hear it also when it is very quiet.
