Please add a reply on this thread if you hear high frequency sound coming out of you device (just put your ear on next to the screen).
i had xda mini (i got that sound) ,now with asus p525 and i have the same sound.
i wanna track why and what is doing this high frequency sound and how to fix it.
PPC-DOC
Was there on Atom. Don't know if it is gone 'cos I don't have it anymore
No sound.
I use P525.

hi victoradjei and vivi
i want to know if u used any screen speed tweak or some kind of tweak for display on your devices!!!!!.
i cant get the sound to disappear but it i have a feeling that happened after after tweaking with tweak2k and easy tweak.
10X and hope to get more replys to trak it well.
I believe, this sound is comming from screen. You can try turn your screen off (with device still running - just as you do with your music player) and find our, if this is true in your case.

DiMCa i notice that is the screen ,but i cant fined the reason. when i got the asus p525 or the htc s100 it has no sound, after a while i got the sound.
but my question is : is it possible that speed up screen tweak has something to do with it???

HI VIVI
did you apply the Increase font cache tweak or did you Increase FileSystem cache ????
thanks
This is totally normal with all devices that use gas-discharge screen backlight lamp technology (ie QTek S100/S110, ASUS P525, ATOM and some others). Some people dont hear it (since its above some people maximum hearing frequency), also its very faint, you need totally silent room to actually discern it.
The sound is coming from high-voltage DC-DC converter, its impossible to make it totally silent.
Since its related to backlight lamp, it will be gone if you switch the backlight totally off (and sometimes on full brightness too if its related to intermediate modulation harmonics). No screen tweaks will help (because its backlight-related, not screen-related).
Devices that use LEDs for backlight have no this sound (these are all modern HTCs as far as I know), but their backlight is tad dimmer on maximum, sometimes has issues with visible non-uniformity of backlight, and its more expensive technology too.

Yes , I use SK Tools.
I don't hear any sounds or my ears are too bad.
This have nothing to be with ears being "bad". Maximum hearing frequency is a genetic trait, also it tends to be reduced with age.
The backlight sound issue was officially confirmed by ASUS tech support, why is happen and that is totally normal and not considered a defect.
They also had troubles to confirm it initially, but finally did it in a quiet test room - every P525 device has it same. Maybe few have it too loud though, I dont sure about that.
Hmm..
Strange...
I test it together with my daughter ,15 years old.She also told me that no sound heard even with 100% brightness.
On P525 you dont hear it on 100% brightness, since secondary modulation is disabled at 100%, and on P525 its harmonics-related.
Its heard on intermediate brightness only. Built-in mike picks it too - its quite discernable if you compare two silent sound clips, recorded with, say backlight off and other with backlight at 30% and high recording volume.
And, as I said, maximum hearing frequency for human ear is a genetic trait. Since this is your daughter, figures
Thanks Ingvarr for clear details.
I finally heard it,but with very silent sound.
I have to put my ear tight with the screen.
No significant in daily use since I never put my ear on the screen as close as that.
BTW,Thanks again.
hi hi
Ingvarr its screen related and (cache or cpu related),i have been since 3 days extremely testing both xda mini and asus p525 to fined out the reason or what is doing that sound.
and what i got till now:
1. my ears are very sensetive :-(
2.i turn off back light and the sound still the same (not backlight issue)
3.i turn off screen and the sound will disappear (screen issue)
4. the sound change to other frequency,when i load something or use pocket sand or charge the pdas
5. i try to decrease system cache and font cache (i didnt c or hear any difference).
thanks all for your opinion and help.
still investigating for the reason and how to solve it.
PPC-DOC
Well, then its something other in your case.
Contact tech support about it, you wont be able to solve it on your own, and most likely will require unit replacement, since its hardware issue.
But be aware that even if you eliminate "processor-related" sound, the backlight sound will stay here no matter what you do, and you with your sensitive ears will still be able to distinctly hear it.
dear friends, something strange happened with me
I used to increase the volum of the calls during the call itself .. and today i noticed a noise accompaning the voise of the caller .. i need to decrease the volum till the end to decrease that noise while iam in the call

i dont think thats what he was talking about.
if you had the same thing i had with my touch pro/fuze, its a low buzz or crackle. it developed after a few months. att replaced the phone with no more info needed. then new phone didnt have it so its something hardware.
i had muffled incall sound and it sometimes crackled too, this cab solved both problems.
the background noise stayed though.
there is also an option "reduce or supress incall noise" in advanced phone options. try changing it to always
Thanx my friends
I tried the cab ... but nothing happened
the thing i have is a buzzing sound in the ringing tone itself ...then when i receive the call if the caller is speaking loud or iam putting the volum high then his voice will have a buzz like sound when he raise his voise
now iam putting the volum on the minimum
the ringing tone still buzz , but the caller voice is better with low buzz if ever
do u think really its a hard ware problem ?
i got my pro2 from another country than the one i live in , this will cause me allot of trouble if i thought of replacing the device
yes, my opinion is thats hw
these sw tweaks only improve sound a little, but not solve the whole problem
there are a lot of complaints on incall sound among different modern htc handsets (tp2, d2, hd2, hd)
Hey friends,
Hi from Istanbul to everyone. I have a rediculus issue with my HTC Desire GSM.
Incall volume is too low. I mean, I'm adjusting to high level and close the settings. Then I'm making a test call. It's again low. Then I'm opening the settings and again seeing that it got low level by itself.
Why it's always getting to low level by itself. I can't hear my calls.
pLS HELP ME
I believe some ROMs (maybe all, not sure) automatically lower the volume of the ringtone when the phone detects that it was moved.
Maybe the accelerometers get triggered to soon on your phone? Try calling your phone, but make sure it's laying still on the table or something...
Grtz
Thank you very much friend... but I am still having this issue
I am having this issue with the custom ROM 'InsertCoin CM7'.
I can barely hear anyone I speak to on the phone and this was not an issue with the stock ROM I had before.
If there was a way to set the in-call volume, that would be incredibly helpful.

Same problem here. My voice is very muffled and to be honest I'm getting tired with having to shout down the phone. Everyone says it sounds like I'm underwater or have my hand over my mouth.
Anyone know what's caused this? On the Trinity Vengeance RaptorXL 2.5 JB ROM

I've been trying to work this out for months. There have been a LOT of posts about this on the Sony forums, but no one has a definitive fix yet. Some people have fixed theirs by turning off noise suppression. Others have fixed it by turning off vibrate when ring. Others have restored their firmware 3 or 4 times before it went back to normal.
My fix was to press the volume rocker a few times when picking up the call. This would normally work, however lately it hasn't been doing a thing.
Hello, yesterday I found a problem with my speaker. It makes strange sound after displaying any audio, like 2-3 sec noise after displayed sound. It happen too when I plug in headphones and I hear the same sound on headphones. I hear that for example when I have turned on touch sound or I turn on music. Someone from you has a same problem? Should I give phone on guarantee or It is normal failure of desire 820?
Please for reply.
any ideas?
Go to service center this hardware proble
Ya i have the same problem Actually it happnes when ur data connection is on.. and i dont know how to get rid from it. ?
