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.
Hi all,
Just got me a Sony DR-BT10CX bluetooth stereo headset. I'm new to these things, so I have a bit of a newbie question. The sound is quite good, much better than the ones that came with my HTC Touch (obviously), but there's a considerable static in the background, that seems to increase when I increase volume, but only when regulated on the headset itself. If I increase volume on my Touch (in WMP, or volume slider), the static doesn't seem to increase. I was just wondering if this is normal in these headsets? This headset sells in Holland for just under E100,-, so not really expensive, but not really low end either. Could it be a faulty headset or crappy design?
All thoughts and experiences very welcome...
Thanks,
Driekus
A2DP question
Might be a silly question, but have you tried turning the volume on the Touch up to 80% and turning the headset's hardware volume setting down??
Some A2DP stereo headsets have a particular setting they work best at..
Failing that, you may simply have a headset with firmware that really isn't perfectly compatible with your PDA...
Good luck,

As a matter of fact the volume on my touch is currently up to 100% as is the one in WMP, so that I can keep the volume setting on my headset low, but that's not really how it should work I think. Besides, incoming calls are now very low volume, so I have to adjust the volume on the headset everytime a call comes in (and quickly lower it when I hang up in order to prevent hearing loss...) and I tend to miss appointment-announcements by MS Voicecommand because of this as well.
I guess the headset isn't perfectly compatible with my Touch, as sound sometimes skips (which is even more annoying because it doesn't happen all the time) and my pda doesn't automatically connect to my headset (solved with A2DP-plugin, see http://forum.xda-developers.com/showthread.php?p=1503123#post1503123), but I'm not sure whether the background hiss is because of this too.
Hi, this is my first posting on this forum (which I have been reading for a while) and I take the occasion to greet you all.
I've got a Samsung i780 (Italian brand TIM) and I am very pleased with the same. However, (maybe because I'm deaf although I don't think so) I find the volume-output of the earphones very low! I read on an Italian forum that by using the code:
*#0002*28346#
one gets access to the volume panel control of the i780 and from there one could probably increase the volume-output for the earphones.
I'm a bit "nervous" of accessing said code and before doing so I wonder if you can let me know if:
1) once entered in the service-menu (using above cited code) is there some kind of exit (without saving) for instance like when ones enter the BIOS-settings in a PC?
2) has anyone already modified the volume with success?
3) is it straight-forward or are there many parameters to change?
Any help/input from you would be really appreciated. If someone already have a procedure (or a link) that would be really great.
Regards,
/tilleke
I would also like to know if this can be used to increate the PHONE volume as well, which is too low for me, the lowest of all phones i had...

indeed it will take you to a menu that allows you to control several variables related with sound... did not test, but it was a good hint. I'll post my findings when I have the time to test it
Samsung i780 - service menu?
Hi guys.. inspired by the *#0002*28346# code for changing volume (which works well by the way..) - I was wondering how to get to the following menu:
[1] Debug Screen [2] Version Information [3] RF Test [4] UMTS rf nv [5] Read gsm rf nv [6] Write gsm rf nv [7] NULL [8] Audio [9] Common ”€\ [1] Basic information ”Ź\ [2] MM Information [3] RR Information [4] GSM Neighbour Cell [5] GPRS Information [6] SIM Information [7] Handover [8] Phone control [9] Antenna & ADC Test
These strings (basic menu) and even more interesting ones(submenus),can be found in the i780_DXHC4_Rev12.img file, I guess it's some kind of service menu, yet I've no idea HOW to get to this menu... anyone does ?
it is indeed possible to enter and exit the menu without changing values. just pressing ok.
...and the settings survive after soft-reset... I guess they are stored in the nvram. Great for making by bluetooth handset louder
What exactly did you select in the menu to increase the volumes of the phone? there are many paramters in every menu, is there some manual for this?
Many thanks for your replies. I will now try it out.
In any case, if someone obtain some real good results it would be great if you could post a more "detailed" procedure. I will do this myself as well.
This could be useful for other users as well.
Thx and rgds,
/tilleke
There is no manual.... but generally....
TX - controls how loud people will hear YOU
RX - how loud YOU can hear ppl
- XX dB .. +XX dB .. logarithmic scale.. negative values decrease volume, positive values amplify volume, 0 dB = "original" sound without any processing (decrease/amplification)
Works also with the ring tone volume, speakerphone volume, media player.. everything - and values are retained after soft-reset, but reverted during a hard reset.
I've attached the app that is launched with the key combo.. can't launch it manually though, any idea why? And also, where are the values stored? They are applied immediately..
Hi,
Its still not clear how to adjust...
1) what's the difference between Normal Mode / Talking mode ? Normal does not have RX / TX...
2) I will use TX to increase hwo loud i can hear people but what is the other settings (RCV, MPBST, MVOL, M2BST)?
Can anyone post the original settings here, please. I accidantly increased the microphon sound of my earjack and do not know what parameter it was. I want to avoid a hardreset of course ...
what was the problem after increasing ? is it too loud?
I did some chnags andI am really happy with them

yes, too loud. the caller told me he wasn't able to understand any word because of scratching noise.
Can you post your Settings? Maybe they work for me too...

Hi Dirk
so sieht man sich wieder
HP :-7.7db
RX:-6db
MPBST:+12db
MVOL:0db
M2BST+0db
TX:-6db
Das sind die Einstellung vonTalking/Earjack. Reicht dir das?
I don't know how to increase my microfone. I tried many settings but no results. Could someone help me? which setings I must change to increase volume on my microfone. Sorry for my english. I'm still learning.
found this on wordpress.com
Here’s a tip from Gavin to tweak the i780’s volume-
*#0002*28346# code for changing volume
TX - controls how loud people will hear YOU
RX - how loud YOU can hear people
- XX dB .. +XX dB .. logarithmic scale.. negative values decrease volume, positive values amplify volume, 0 dB = “original” sound without any processing (decrease/amplification).
Works also with the ring tone volume, speakerphone volume, media player.. everything - and values are retained after soft-reset.
Thx Reyals but I read this before. I set this:
Talking -> handset and Earjack:
TX to 0dB, next time -1,5db and -46,5dB (Available value for this setting: from -xx to 0dB)
next menu and apply.
I didn't see any difference. Maybe I chose wrong setting.
This information is very useful to improve the talking quality of BT handfree
If you own a BT handfree with DSP and use it on i780, you will found that other people can't hear what you are talking.
Your voice will process two times in BT handfree (DSP) and Phone (TX -9dB). it result the voice is very LAG for hearing.
But if you use a BT handfree without DSP it will be fine.
Therefore if you use a BT handfree with DSP, you should set the TX in BT mono to 0db.
P.S. I found that the i780 is REAL stereo BT (A2DP), not same as HTC phone used joinstereo. and the BT sound quality on i780 is great with my plantronic 855.
I've been playing around with the settings but I have not managed to increase the volume-output of the earphones (for listening to music). I have tried all possible settings but in vain
Someone who knows what settings to change?
Thank you.

I've managed to tweak the VZW TP2 earpiece volume down to some comfortable levels, but now am faced with the problem of the speakerphone being too loud when changing to it.
I've tweaked the PHONE_HANDSFREE_VOLX lines, specifically the rxVolume and rxCodecGain columns and put in a value 1/8th of their current value... and it does not seem to make a difference.
Is there another row that should be tweaked?
Is there any tweaks, patch to solve the very low speaker (at the top front) of Lumia 1020? It's the only thing that makes me think of having another phone. Tsk
