Strange whistle all the time

Dear,
I have a problem, and I'm not sure if it's possible to fix. I have a X01HT that I flashed many times. From some days ago (I think), it produces a really annoying "whistle" (like a 'piiiiii') that destroyed my ears . I thought that it was a problem of any program, so I try to hard-reset, and also Flash another ROM (even another Radio), but nothing changes. Even after a Hard-reset, the sound never disappear (><) Any idea?
Thanks
César

Is the whistle on in bootloader? In standby?

Have you checked using loud speaker and same noise?
Have you tried muting the volume?what happens?

It is all the time the device is ON: since I press the button and it turns ON until It turns OFF, no matter what it's doing: (rebooting, in bootloader after hard reset, with IExplore, etc.).

Mute the volume is the same; the noise is there.
Also, I notice that I can hear the noise real more stronger when I have the screen in front of me (If I'm looking to the back of the device, I almost can't hear anything).

Then it's just the phone speaker, not the loudspeaker at the back.
I would ask what happens to the noise when you plug in the headphones, but it's a hardware problem anyway, so repair center it is.

We use some Symbol PPT8800 series PocketPC devices (runs PPC2003) and some of our units start making those noises, after heavy use. But generally its shortly before they go pop, I'm afraid to say.
Hope yours is something else.

I plug the headphones, and it's the same.
I also imagine that it's hardware problem (><)

I had the same problem (AT&T Branded 8525) started after I'd had it only 3-4 Months. I'd purchased two and flashed them with same ROM's however, I only had this problem out one. Spoke to AT&T's division of HTC warranty center. End result...it was hardwar problem. They shipped a replacement device @ not cost to me. Problem fixed.

so as far as i can see there is no home made solution for this?

try removing the battery and try and turn on the phone without the battery (it won't go on) for about 10sec this will drain any remaining power in the circuits. Then reinstall the battery and see if that fixes it.
Chris

It sounds like you are having the same problem I have with my 8525. It's probably not your speakers but more your LCD screen.
There have been a lot of complaints about this, with no easy fix other than to send it in and get it repaired/replaced and alot of the times the replacements have the same problem.
I've learned to live with it by turning off the screen when I am on the phone.

That sounds right...so is there anything that we can do about it without sending it in for "repair"?

Speaker making slight hissing and a click noise

Is anyone getting these slight clicking noise from the speaker whenever the phone is in use, like opening an app for example. I got my phone phone from the launch event (5th in line!! ) and i only noticed when it was really quiet in my room these noises came from the speakers.
To check, open an app and quickly put your ear to the speaker and I hear a hissing noise then a soft click. Always happens when i open an app!
I went back to Phones4U, the guy could tell it was faulty so I got it replaced..now same problem!! (not as loud as before, but still there)
Anyone having the same problem? can anyone check for me? this can't be normal!

Yeah I have that problem. It's one of those things that you don't really notice until you know it's there, then you hear it all the time
Someone on another forum posted they had the same, so it might not be an isolated problem.

Isn't that just the touch click?
Try Settings/Sound/Touch sounds.
Personally I rather like it..

No, I have that turned off.
It happens whenever the speaker is used - when the sound stops there is a quiet hiss, followed by a pop as the speaker switches off.
Try it - hold the speaker right up to your ear, and use the volume rocker to hear the beep. Afterwards there is hiss followed by a pop.
It's not noticeable enough to be an issue (for me) in normal use, but you can hear it if you're in a quiet room.

The click comes like 3 seconds after you make an input, so it doesn't sound right and it just sounds random (and annoying).
thanks tho!
Edit: Turning off Touch sounds, seems to stop it, whenever im using the phone..but yeah still happens whenever the speaker is in use but that i can live with that!

Happens with my OG Droid. I only started noticing it one late night when for no reason I had the speaker right up next to my ear.
I don't think it's anything to worry about

Heh, that's certainly got something to do with it
As I say it's not really an issue, and it's not unique to this phone (as you point out). Just one of those annoying niggles - it depends on how sensitive you are to these things

Yes - I have the same problem with my new Galaxy Nexus. In fact, even if it's not a problem for most people, I'd say it is a problem for Samsung because I returned my phone yesterday and got it swapped out. The new one has the same problem, so I assume it's an Android software problem rather than a hardware glitch.
So that's at least two returns caused by this problem. Hope we get a fix at some point!
p.s. Phone is great by the way, even with the annoying click.

Guys
This is hardware problem. And it happens on most of the speakers however its more or less noticeable on some devices.
I have quite good quality monitors (studio speakers) and i can hear something hissing in the back.
Let me put it that way.
Every speaker needs electricity to work. The noise you are hearing is the actual electric current coming through the speakers. The sudden pop and lack of the hiss means that speaker has been turned off. For obvious reasons there is no point for the speaker to work constantly....

I can't hear any click when I plug headphones in, so maybe you're right - the click could be when the amplifier that powers the internal speaker turns off...
However, for some reason I still get a click if the phone is in silent mode. I guess putting it in silent mode doesn't guarantee it keeps the amplifier turned off.

I hope it's just the speakers; the DAC in my HD2 hissed for a few seconds after any sounds even through my headphones. The hissing was always there when there was sound. It was quite depressing. I'm hoping for a good DAC in the Galaxy nexus.

I've got a click (sounds just like a quite speaker pop) from the back cover.
Turn your GN over and push the back cover, on the "Google" logo (below the camera flash). Then quickly release your finger.
Sometime it can happen with only the lightest of touches. If i put my phone down on my chest, the pick it up.
If you look really closely you can see the cover moving just below the camera surround.

Issue has been reported to google.
http://code.google.com/p/android/issues/detail?id=22307
I have this issue on my gnex. Its def a sw problem. I took the back cover off and still have the issue.

slightly different, but also hiss related...
my rezound does the same thing when headphones(or aux to car) are plugged in and nothing is playing. once you start to play something you don't notice it. and its a confirmed issue.

It's a hardware issue guys, depends on the audio chip I believe. Impedance-related.

Here is the other thread with this annoying sound

It isn't just on the speaker either. Atleast on my Galaxy Nexus, I can hear it when listening on high end professional in-ear headphones. I can verify that it is almost certainly a signal isolation problem. The activity causes the DAC (the thing that makes a digital signal into an analog signal that speakers and headphones need) to kick on for a few seconds and until it shuts off you can hear the noise coming out of the DAC. It's pretty substantial on mine though, so I'm wondering if I got a bad unit. I'll have to stop by a Verizon Wireless store and plug in to the display unit to see if it is any better. I never noticed this on my Galaxy S (Fascinate).

My unit is also affected, it was made in Vietnam. I checked the Google Code issue tracker link (http://code.google.com/p/android/issues/detail?id=22307) and I can see many people confirming this also. This is definitely not how the speaker should work - I checked another Samsung phone (SGS II) and there's no such "clicks". There's some silent noise but not the click.
I can hear it from the speaker only, not through the headphones.
I think many users are unaware of the issue because it is often only noticeable in a silent environment.

Yes getting same issue. Have tried different ROMS to no avail

[Issue] Speaker pop

i'll do somthing in the UI to make a sound .. like a touch tone.. then in a few seconds i'll hear a pop from the rear speaker

anyone else have this issue?

Anyone having this issue?
basically.. does your rear speaker pop when the amp cuts power to the speaker ?

cant say i have this happening on mine

Exactly have the same problem. I didn't notice the hiss though, but definitely heard the pops. But yes when I listen closely I with my ear to speaker I hear exactly what you described: a hiss ending in a pop.

On my other phone (samsung epic 4g touch), it does the hiss/pop/silence thing too, but the pop is much much quieter that I can only hear it if I put my ear right next to the speaker.
However on this galaxy nexus it is loud enough that I can hear it from 1-3 feet-ish. Its especially noticeable in quiet areas.
I'm considering return it because of this

For me it's not a big problem. I notice it but it is not annoying me. I hear it only when I'm concentrating on it. BTW just applied the new update and that didn't fix this issue.

I'm pretty sure this happens on all devices. I have this on all my phones, navigation units, clock radios...

Me, too, I just checked all electronical devices I have and they all have it. Though, it's so quiet, that I have to get closer to the speaker than I normally ever woult.
Is that different for the GN? Is it louder than "normal"?

my GN is defiantly louder than normal. I can hear it easily from almost any normal usage distance. It almost sounds exactly like the normal touch sounds so that I get confused and think I clicked on something
pretty sure it's the amp cutting off power to the speaker a few seconds after it makes a noise

Mine does it too. Simplest solution I've found is to turn off touch sounds. That way the speaker doesn't keep turning on and off so often. I would normally turn those sounds off anyway because they are annoying, so it's no biggie for me.

Only time I have noticed a speaker pop is going into recovery

Mine does this too.
Glad its not just mine!

yeah, i thought i was going crazy last night too, but i definitely have the same popping problem
its not very loud , but its there - i heard it when i was in my room cause it was dead silent. Whenever i played any type of sound file, you'd hear the little pop afterwards from the speaker =/
it kinda sucks with touch tones for the dialer cause it happens everytime you push a number
i wonder if google/samsung knows about this and if it can somehow be fixed through a SW patch just like the volume bug haha - cause this LOOKS like a HW issue again

Yes, I certainly also get this, my hearing is very sensitive, so something like this is very noticeable for me.
Even "turn off touch sounds" doesn't seem to stop it.

I would guess it's just something as simple as properly muting the output to the speaker before turning it off. This should prevent the voltage spike from affecting the speaker.
Its not unique to the Nexus - it can potentially happen to anything with a speaker that isn't muted before turning off the amp.

[Q] Delayed "Pop" on Speak phone?

I am on my third replacement phone (last one the LED notification didn't work) and now I am noticing that there is a very faint 'Pop' sound emitted from the speaker phone 3 seconds after there is a system audio sound. For instance, every time I hit the Home button or unlock the phone, I hear the 'Pop' three seconds later.
Does anyone else have this problem? If I have headphones plugged in, I do not hear the sound through the headphones.
Thanks!

Dude is it possible that u have the lock n unlock sounds enabled?

Yes I do have the sounds enabled and I hear those fine. I am hearing an additional click/pop noise 3 seconds later. It makes the sound pretty much every time the phone makes noise. It's very faint.

From what I've read this is a pretty common problem. Mine does this as well but honestly I can only hear it when its quiet.
There's also another thread on this topic but I don't believe there was really conclusion.

Mine and a bunch of nexi at my local best buy suffer from this. It is not dependent on lock sounds it's a problem with the DAC I believe

Gotcha. Are you boosting your volume with volume+ or any other app?

Thank you for the replies. I'm glad to hear I'm not alone.

I have the same problem. I posted a thread yesterday, and there's another one (i didn't see it before posting mine).
That's a pretty annoying issue, i used to have the same thing on my unibody MacBook (fixed with an unofficial software patch), and once you hear it, well, you can't unhear it.
I hope this is not a hardware issue and can be fixed by some patch, but no one seems to care about this one (maybe not all GN have this problem?)

I decided to just disable all touch tones since it was bothering me too much. Just out of curiosity I checked another Nexus and the pop is still there but could only be heard by literally holding the speaker phone to my ear. Not nearly as loud as mine.

Yeah dude.... same. I actually started the original thread on this. Its so annoying hey.... I hear ya man. I dunno, I did the same as you, disabled touch sounds. Its sounds cheap doesn't it.
I really hope its software related. I was trying to find out if, just a bit of 007 work, Haha, if it was maybe the build? Seeing if the people with a Google updated nexus's had the issue compared to people with the Samsung updated ones. I wonder if there a connection....

problem with vibration on pixel xl

Hi guys. I just started to using it today and came across very odd issue. The vibration seems to be broken. I can barely hear it working and cannot find an option to increase its intensity. Is anyone facing the same? It sound just ridiculous for a phone that expensive.

My vibrator seems to be working fine. Only had the phone for a day so far tho.

Not sure how quiet it is for you, but I think they are all pretty quiet. If I had it sitting on a table I wouldn't hear it. If you root and use a elementalX kernel you can increase the intensity, makes a huge difference.

I am thinking about rooting it, and I regret I didn't do it first thing. After restarting the device the system message pops up a with "vibration intensity set to 70"...

With me occurred the opposite.
I'm so disappointed about that issue.
I simply loved the phone, but on the second day of use the strange vibration noise started.
For sure, in my case, is a manufacturing defect.
The vibration motor seems to be broken. The vibration mode is so intense, that it seems to make a "scratchy" sound at the end of each vibration. It's almost like the vibration motor is loose or something inside the phone is loose and the vibration noise gets worse.
And the worst of all is that I imported the phone to Brazil, and now I don't have any idea how can I receive support to my phone.
