i have a tmobile wing it seems that when the screen is on, theres a loud high pitched noise and a rough buzzing coming through the earpiece. but when i shut the screen off and the phone is running, no more noise. the time i really use the earpiece is when im actually on the phone talking. is there an program or something that can shut the screen off automatically when im connected on a call? that would be cool. thanks for reading
homescreen plus plus (battery meter)
tmobile wing settings
omapscaler: min:97mhz normal:201mhz max:201mhz boost:247mhz
omapapp: phone: 247mhz
It's the interference between the processor frequency and the lcd screen. It's not actually coming from your earpiece... it's the whole screen while it's on. It gets worse if you set homescreen plus plus to a dynamic processor speed... Under 200mhz it becomes louder and much more audable. At 247 you should just have the high pitch tone. No way to get rid of it. Except do like I do, press the power button and turn off the screen everytime you have a conversation using the earpiece. Just letting u know, it's not only you that the phone makes that sound. On my 2nd wing (herald) because of it before I realized it's simply a design flaw. They all do that. Old folks won't mind because they can't hear the high pitch... I've experimented lol

Hi guys,
I've found a very interesting sound effect on my O2 XDA Mini (=Magician). I've been having the phone for a few days only, but right from the very first calls I noticed that the speaker creates a very high frequency continuous beep-sound, not loud of course, but crazy high, something like the well-known side effect of the old CRT TVs. At first I thought it is produced during a conversation. Then today, I held my phone to my ears without any calls, and guess what: the beep is there. :shock: It's produced always!
I started to look around, and had a hunch that the LCD backlight can be the problem. I played a little with the backlight setting and found that I was right, the sound is poduced only when the light is set to low. It's loudest at the first notch of the light slider, and gets more and more quiet as you set the backlight higher.
Now I wonder if it's a special problem with my phone (like some bad quality filtering somewhere in the power electronics of the backlight system) or if it is the same with your devices.
Please try it and post your comments. Listen closely! And try both ears (not kidding), the sound is very quiet and very high in frequency, so your ears may not be up to the task to pick it.
Have to be honest I can't get a quite second at the moment but I'm pretty sure I've noticed this noise before as well. Another noise which can be irritating is the GSM radio module and it's intermitting buzzing (a quiet version of what you hear when unshielded speakers pick up your signal).
So basically I'm not sure but I think it's a generic issue with the backlight
Hi,
I found that too....
it's quite irritating as it looks like an old TV turned on.
I hope that won't be a problem to our ear in the future
After about a week of usage (no problems at all), a very high pitch tone is now heard whenever the display is on. If the display is turned off, everything is nice and silent.
This tone is (pure guess here) about 10-12.000 hertz and very annoying since you are holding the phone to your ear during calls. It can be heard from about 5 meters away in a silent room.
It does not matter if the sound volume is off, on vibrate or on. It does not matter if the display backlight is on or off or what level the light is at. A hard-reset didn't do anything either. It also does not matter if WiFi, Bluetooth of the phone radio is on or off.
Any guesses? Should I just return it for repairs or does someone have a fix?
Best regards,

It is usually the backlight lamp emits this buzz on some PPC...
But u mention you hear this even the backlight is off...
That's weird... but u need to exchange it back ..looks like HW issue to me
Hi Soren,
Definatly a hardware issue - I'd send it back for repair.
It sounds like the PWM (pulse width modulator) circuit has gone funny. This circuit produces the required -10v or so the display requires from the +3v battery. It's quite common to hear a very low buz at the frequency you mention on most phones.

A few days ago my Cingular 8125 /HTC Wizard started making a very high pitched noise. It's coming from my ear piece speaker. If i press the power button to turn the screen off the noise goes away.
Has anyone else got this?
Cheers,
Chris
maby underclocking your processor
I had the same kind of thing for a while.
Then i noticed it was caused bij batterystatus which I used to overclock but also underclock my wizard.
The lower I clocked it, the more noise it made.
Maybe something for you too..
(it happend only in IDLE of course because then it was only running on 148 for instance.
I hope it helps you..
I just got it and noticed the earpiece volume is still low even with the volume turned all the way up.
Is there a setting I missed or maybe a registry fix?
Any help would be appreciated
HTC HD2
OS 5.2
MANILLA 2.5.2
ROM 2.13
RADIO 2.10
Don't mean to offend you. I had the same issue but was more of a user issue. I kept increasing the volume not paying attention that I was adjusting the ring volume and not the system volume.
if that doesnt work you may need to return it. My friends HD2 had low speaker volume and low earpiece volume. As much as we tried, we couldn't get it to go.
N1M1TZ - No offense taken, I only adjusted the volume during a call and at max it is still quiet.
I checked the settings/sounds, no adjustment for the earpiece just the ringer and the system sounds.
marduk79 - after doing a little digging I have found that this is a common problem with this particular batch of phones.
The first batch came out and the volume was set way to high that it was actually blowing out the earpiece.
I think I may have found a solution, if it works I will post it.
Thanks for the assist.
So what is the solution... My first one had sweet loud ear piece volume. But alas, the speaker blew. My replacement is alright, but I want it to be a tad bit higher... Lots of years of loud punk rock have made me slightly def I think...
Anyone know if there is a cab or registry tweak or something that will make the volume louder in the ear piece speaker?

How low? Like so low you couldn't hear it, or just low enough to be annoying? Basically my first HD2 was nice and loud. The new one is about 3 bars lower sounding turned all the way up... Which annoys me because I know the other one was louder and it's hard to hear people if I'm in an environment with a lot of background noise.
I feel like if I tried to take it in to get a replacement they would think I was nuts.
headphone and phone speaker too low
I too beleive the headphone volume is way too low, when listening to music or taking a call on the headphones it is barely loud enough too hear if there is any background noise such as traffic or conversations going on nearby. I have the volume about 75% when listening to talk radio stations, on my headset, no background noise present and it is at normal listening level. So if there is background noise, I need 100% for it to be loud enough to hear clearly. The phone speaker is not much better, when listening to calls on speakerphone the percentages are about the same for equvilent listening circumstances. I have tried "AudioPara3 TMO" and notice little or no difference in sound. Does anyone know of anything that will increase the maximum volume level for both speakerphone and headphones?
I'd like to know if there is any registry hack to increase the line out volume as well. My line out volume is very low, I have to put it to about 50 percent to match what would be the 20-30 percent level of my old HTC Touch (Touch 1 to HD2 - quite an upgrade, eh?? )
So I am getting this buzzing/hissing sound from my ear speakers. It is only noticeable when I hold it very close to my ears in a quiet room. But then it is quite easy to hear. The sound changes all the time. The frequency is different and there is a click sound every second or so.
It doesn't matter if the screen is on or if the phone is in stand-by. A restart didn't help.
I have never noticed this before so it might be my manual update to stock 4.3 that caused the problem. But it might have been there before the update.
It is not really bad because you only notice it when you call someone but it might eat up my battery.
That's normal and not even exclusive to your (our) phone
It's caused by electrical noise
