Internal phone speaker doesn't work

Hi everyone,
I have a problem with my XDA Exec, basically, the internal phone speaker doesn't seem to work. External one is fine (the one on the outside of the case) but the one next to the screen does nothing.
It did work when I first bought it. I have since upgraded to the latest o2 rom. However I cannot remember if it stopped working exactly then or later!! Daft I know!
So I just wanted to ask if anyone else had this problem after upgrading the rom (I am using 1.30.107 WWE, radio version 1.09.00), and if so, is there a way to fix it? If there is no one else with this then I guess it is a hardware fault and will return it for repair, but wanted to check.
Cheers
Rick

Anyone? I don't mind if the answer is just "Mine works fine", I just want to know if anyone else has experienced this with the same rom version as mine, before I condemn it and return it to the shop.

I have the same o2 rom as you mentioned, and have encountered no problems. Im sure its a hardware problem, caused by dropping the phone etc, rather than a software one.
o2 offer a free replacement within 1 month if you got it directly from them, or I suppose you could get it repaired from somewhere. Im not sure if the speaker is covered under warranty, but might be worth a shot!

Thanks. I have had it about 4 months now I think, I would bloody hope the speaker is covered by the warranty though, phone ain't much use without it :shock:

By the way, are you sure the incall volume is turned up!!! Just making sure!
If it is, why not try a hard reset just to see if it helps!

Just gone through the same problem.
First of all try to put the jack of the headset inside the hole and twistle it.
If it doesn't solve the problem, I'm afraid you need a replacement.

I had the same problem a week ago. Every speaker worked, except the one next to the display. The problem appeared somehow over night ... I definitely didn't drop the phone or did something "rude" with it.
Unfortunately, I don't have the original headset to exercise this plugin/plugout/twisteling method as mentioned by lautunno, so I tried this with a regular headphone. Without direct success
A hard reset didn't change anything.
... but after a few days of trying almost everything, the speaker started to work again and still works without any interruptions :?
I'm not sure if it's really hardware related because there are so many people with the same problem and almost everyone of them has fixed the problem by just powercycling the phone many times, plugging the headset in and out, fiddling around with the phone app, etc.
As far as I know, the radio firmware is responsible for addressing this speaker (because it's only useable as a phone speaker) and this part of the device firmware doesn't get resetted when you do a hard reset. Maybe it stores some settings (like headphone mode?) in an EEPROM or something like this.
Anyway, good luck and keep trying.
.ox
ps.: I'm also using the O2 firmware (1.30.96 GER) but I've upgraded the radio stack to version 1.11.00.

Suddenly lost all sounds

I had been using the great PDAVIET 4.0.0.0.6 TOUCH for almost one week D ) and had installed some software among which is TomTom v6.10 which I was using with my GPS on the road and suddenly the GPS quit talking to me! My Prophet (Qtek S200) never talked again!
I've done the following without being able to recover sounds from my Prophet
1.- soft reset
2.- hard reset
3.- installed Propeht_PV_Temp and then PDAVIET 4.0.0.0.6 TOUCH (At this point the Prophet was able to sound when tapping the screen for about one minute and then lost sounds again)
4.- Installed RUU_Prophet_220734_2207114_024721_NVID.exe and then PDAVIET 4.0.0.0.6 TOUCH
5.- Installed RUU_Prophet_220734_2207114_024721_NVID.exe.
It doesn't even beeps when requesting to tap the screen to start setup after a hard reset.
What is weird is that at a given point and after 6 hours of total silence, it was able to sound for about 1 minute between steps 3 and 4 above.
That looks like a hardware problem, right? Or is there something I am missing or I can do?
Thanks for your opinion.
Addition: I took my Prophet to the seller and they found it to be a hardware problem: one of the speaker connections was loose. When they fixed it, sound was on and off. They later discovered that it was problem in the speaker itself. Somewhere they read this to be a fairly common problem that could be fixed placing a small piece of choth behind the speaker to have stay in place. I did not want that solution and the Prophet was sent to the wholesaler for waranty. It will take 10-15 working days to return. I will post the results.
(Zeusin & JTA, thanks for your help)
---- Finally received my Prophet back from the manufacturer. The speaker was not working. I got a new replacemente prophet. CLOSED!

Hi,
I faced something similar with my prophet, first the sounds went off completely, and then they came on for a few seconds. Then it went coompletely mute.. no sounds
It was a hardware issue, most likely a loose wire connection to the rear speaker. Mine was repaired in 15 mins, so i guess its a common problem. Hope that helps

Welcome tot he forum
Hoping that is not a hardware related problem I would do a reflash to try to solve it
Read in the Wiki on how to
Hope it helped,

That happens one day in the car travelling home that the sound suddly stop working i restart the xda and everything (not reflash) but nothing work i will try to reflash it because i think is not a hardware problem

is the first time i try to reflash my pda but i have a problem when i try to downgrade it that shows error 260 and i dont know how to fix it

ok, i fix the problem with upgrade xD my english is not good at all and i missunderstand some of the instructions, but after read 100k of threats and 5 hours trying things now is upgrading to tomal rom i hope that this will fix the problem i had before

after reflashing the ce two times the sound is still not working, i am updating now the radio from 1.09 to 1.15, the stereo speakers make a little bit of noise when a sound is played, the headphones dont work, the phone speaker works propertly, and the microphone works but only send the voice to the phone speaker ¿? i dont know why happens this last thing

radio updated and the problem continues anybody can help?

I think it´s a hardware related problem
Try to take it to a repair center
Good luck,

I have the same problem. When a sound is played it just clicks and that's all. I had a problem with my ribon cable and I took it out. I've done that before (it's my second cable failing), so I knew what I was doing. I was off for a about a month untill I got a now cable. When I put it back together, I had no sound, just that click thing. I can't take it to a repair center. If anyone has a solution, please share.

I also found that my camera does not work. It says Failed to initialize camera. 36001:100:1. I tried a different rom, but still have the problem.
Also I tried to make a phone call (I'm not using it as a main phone, that's why I just found that out) and I can hear the other person, but they can't hear me.

i also check my camera after reading your comment and i also have the same problem, next month (because this month i will travel and i cant do it) i will send it to repair a tell you what the solution could be
PD: orb3000 muchas gracias por ser tan atento

I have good news. Something happened. I dont know what i did... but i got my sound back (and camera. main camera at least).
As you I flashed the rom, then the radio rom and I still got the problem. So I thought I'll leave it like that untill I find a solution. And I thought.. well i can at least play some games on it and I downloaded Archibald. I put it on the phone. Started it and ?! I had sound. Again I dont know if I did something before that, but I got it working. I'll attach the game, maybe it did something. Give it a try.
Again I have no idea what I did. It might have some bad connections somewhere. I remember I had the same problem (either with the Universal or the Wizard) but dont remember how I fixed it.
Here is a link for the game:

i install it but the miracle didnt happens i also will try to remove the battery it have on the motherboard to make a cmos clear (like in a normal computer). Lucky you i will keep trying

I'm sorry to hear that. I didn't if it matters but my small mb battery is dead. Apperantly it died during the month the battery was out. Everything works except that when I do a soft reset, the clock resets too.

I have these problems too, does anyone know the specification of the mobo battery?
I have the sound problem but mine doesnt work even with headphones in and i also have a problem with the keys being activated when the screen is in a certain position. Could all of these problems be casued by the ribbon cable?Rob

As far as my expirience goes with the ribon cable, it commands the touch, the lcd, mic, speaker on the lcd part. the keyboard has it's own cable. and it snaps to the motherboard. maybe it's loose or something. For the battery I got http://cgi.ebay.com/Dopod-D900-900-T-mobile-MDA-IV-Qtek-9000-backup-Battery_W0QQitemZ350170469398QQcmdZViewItemQQptZGPS_Accessories_Cablesthis on ebay. But mine looks a little different.

also happens to me when i make a soft reset the clock also restart could be all because the mb battery is dead?

OK, we are getting somewhere Since my sound got back, whenever I reset I get to keep my current time. So maybe my mb battery fixed itself or charged.
I am pretty sure now that is what's causing the problems. If you could disassemble your pda, try playing with the battery. See if it is not loose or something. Try to short-circut it. Get a something form metal and touch both pins. Also try leaving your PDA charging over night.
I hope you fix it since I cant seem to find that kind of battery over the internet.

Questions and Answers Section for BA Forum. Post Your Questions Here.

@All,
As a celebration for my 1000th post, I decided to open a new thread based on Tweakman's idea, which seemed to work very well in the Development and Hacking Section. The idea is simple, a single thread for all Questions, Problems, and Concerns regarding Blue Angel. This includes, but it is not limited to:
[highlight]*Problems with Flashing.[/highlight]
Can't get your device in bootloader? Did it freeze during flashing and now it doesn't get past the 4 colored screen? Are you a complete noob and need some guidance as to how to flash? Etc.
[highlight]*Have questions about which Rom is best?[/highlight]
[highlight]*Want to install software but don't know if it is compatible with your BA[/highlight]
You get my point. All the questions that I have seen/answered over the past couple of months are just repetitions of posts, threads, and things that are readily available on the wiki or in other threads. However, people are either lazy, don't know what a Wiki is / where to find it, or just flat out don't know how to search (or read the forum rules for that matter). Having something general (in this case a sticky) that says "Hey, if you have a question, you can ask here" should draw enough attention and start minimizing the number of new threads and posts opened by users (both new and seasoned). This way, we will be able to keep the development threads a little cleaner and smaller... hence making the site's search function work a little better in the process.
@Seniors,
Kinda like the Q&A team, I will need your help in trying to keep the influx of questions to a certain level by answering them as we see them. None of us are logged in 24/7 (or at least some of us aren't ), but if you guys see a question, please try to answer it. I know that xplode, Chef_Tony, markanthonypr, red_hanks, sun_dream, imatrix, +Que_PPC, motisu, and others normally try to keep this under control, but if we centralize it and contain it, we will have a cleaner forum.

Reserved for future use.

my friend has Blue Angel,he has strange problems.
in (sounds & notification),it didnot saved after changing any parameter,we tried by reflash the rom again,but nothing changed,also we reinstalled radio 1.15 but no change,also the ring tone of the msg is discontinue or irregular when played,and some times didnot wake up (of the device) when recieve a msg.
this is strange issued problems but in mine (BA) every thing is ok,this problems only in my friend (BA),I mate PDA2K.
any ideas?any suggestions?
thnx

Hey homam,
Thanks for kicking things off
First of all, which OS were you having problems with? This is important because it could have been a bug in a rom that could have been fixed in a later version.
@mark,
I know I can count on you, buddy I need help from the mods as well though. I cannot redirect posts to here and/or close threads

My BA, keeps turning on from standby, by a light shock! I maen, if you press the Power button, and then you knock gently on it's back, it turns back on!!
I've set to "Lock all buttons except the power button", However, I still have this issue.
Well, I must confess that once it dropped off of my hand, and it's the result of that...
Any ideas?

by "it turns back on" i assume you mean it wakes up from stand by, it doesn't really start like after a soft reset, right?
since the BA's only battery activated wake-up is in the cradle and we are not talking about soft reset, my first guess is, the battery is not to blame.
have you checked whether you can use your camera at all time? i mean, the camera_detect does not usually run at all times but if the camera connector is a little lose, from now and then it could "discover" the new camera hardware and wake up, that is unlikely for normal devices, but if yours had a crash before...
you could refer to this site for checking possible hardware reasons:
http://www.land-of-kain.de/ppc/mda3/disassembly/
the hardware things aside, there are also many possible software reasons for the device to wake up on:
- update of titanium weather
- automatic email checking
- cell broadcast
- if bluetooth is on
- if beam is on
- automatic update of any software...
plus of course the usual:
- incoming call
- incoming text message
- incoming mms
- upcoming calendar event...
so please check the possible software wake ups first to make sure this is really a hardware issue, because that would be a shame, that could be tricky to solve.
or let me put it this way, if it is really the moving that wakes it up, you have the first BA with accelerometer
EDIT: last but not least, it could only be a bug, maybe a hard reset or change of the rom could also be a way to go, since spontaneous waking up is a known bug for BAs
Chef_Tony

If there was only a way to hack the hardware and make this work at least on Edge. I can live with everything else, but its a shame paying for a full unlimited Internet service and only getting G connection Sighhhhhhh
Ok, I had to let that frustration out !!!!!!

Wow! Tony! I really appreciate your complete answer. I mean it.
Yes, as you correctly assumed, I meant wake-up. It just wakes up and continues the routine WinMo operation; no soft-reset occurs.
It's less than a year that I've replaced the battery with a new one. I remember all the funny things used to happen when the old battery was dying. But non of them were similar to this one.
It can't be the Camera. Well, I'm able to use it all the time, and the "camera_detect" has been always loaded in the processes whenever I've checked it. About the looseness thing, ummm, I'm not sure. I tried to knock on it to see if it's more sensitive than other parts. I think the upper part of the device is more likely to wake it up by an easy hit (like knocking). but it's the whole upper part, not only the camera section nor the camera button.
Unfortunately, the software possibility, is unlikely to be the problem:
I've used many ROMs on my lovely BA which 3-4 times of them taken place since the wake-up problem.
The software and the usual reasons you counted, do wake it up. but shakes, too.
Finally, to be honest, I'm agree with you! This is the first Blue Angel with accelerometer. yeaaah! I did it!
I bet my friends that I can wake my BA up, without touching any buttons or screen! It's fun this way, but I comes to be annoying when I put it in my pocket or just put it on a table! and it wakes up... consider the forced battery consumption, unwanted screen taps if I don't lock the screen. God bless A_C! and... .
I know it's a hardware issue (((((

@raizaM: My Thought.... Have you ever taken it apart? One of my BA's had 3 loose bolts inside. All 3 were from what I think is the Radio/Antenna part at top. However, in my case, I had a rattle going inside. Thats why I put it apart. You might have something loose inside, causing a connection to arc when you knock on your phone. If you do deside to open it, there is a tutorial on the wiki on how to.

Hey mark!
I had that same issue a while back, but with only one screw (also from the same area as yours).
@raizaM
Just to knock off Chef_Tony's theory out of the table completely, try to erase camera_detect.lnk from \Windows\startup and SR your device. If Chef was right, then your issue might be gone. However, I would follow markanthony's advice and take it apart in case Chef's idea doesn't work.

Oh man, your not my hero anymore LoL.. and here I thought I would be the only one with a mechanic inside my phone.

Actually, I tried to remove "camrea_detect" from the startup once, but any way, I gave it a shot again... no success...
Frankly, I'm a lil bit afraid to take my lovely BA apart... :-s... What if... :-(
But, I guess sooner or later I need to do so. so what the heck... lets do it.
Maybe I'll do it tonight. Guys please help me through it. I don't wanna loose my Angel!

raizaM: You're not going to go that far deep. Only remove the cover. If you look at picture #4 on that link, the top green area has about 6 bolts all around it. Those were the ones that were loose on mine. 2 of them were rattling inside the phone. I still can't believe they didn't cause a short circuit. You don't need to go down into the camshell area. Do you use the sliding keyboard? If so, you could have a bad flex cable. But, don't worry about tha for now. Just remove back cover and carefull inspect for loose bolts. Don't over tighten them.

all the master please help, my BA strange,,,,, the screen suddenly go dead after actived wifi or playing game, its suddenly dead, and i must push power button to turn it on again through proses like softreset, that in battery power. but if i conect in charger power mode, i turn wifi,playing game, its normal, the BA still on and working normal,

It seems that you have the backlight settings set to dim/turn off too fast. Go to \Settings\System\Backlight and modify the settings in there (particularly the ones labeled "On Battery Power"). Then, soft reset the device (stylus on the bottom).
Hope this helps.

not the setting, it got black scren, its dead screen after running wifi or application, suddenly goes dead, black screen,.

Have you tried with another battery? It sounds to me like your battery is about to die. It won't hold the heavy battery consumption of Wi-Fi and heavy CPU usage while on Games. Try with another battery. Also make sure you followed Egzthunders suggestion to change your Power Settings. If you still need help, post back and include more info about your device, such as, what version of Windows are you running and how old/new is your battery.

Never seen a problem LIKE THAT ...

I`m having an awful problem with my HD2.
When using the GSM Band the phone drops almost all of the calls when I cover the proximity sensor. I have tried all ROMs till now but that didn`t help. Also made several hard resets ...
So after a hard reset the Network Band is set always to AUTO. At AUTO when the phone switches from 3G to GSM it automatically ends the call. That`s why I tried using just 3G. When using 3G I don`t get drop calls. But when I tried the GSM option I get it all the time. I have 3 or 4 signal lines, but it still drops the calls.
When I don`t cover the proximity sensor and leave the phone on the table the call doesn`t drop at all - it works perfect in GSM or 3G. That`s strangest part of the problem. How come the proximity sensor has anything to do with the Band of the phone ???
I don`t know exactly what to do .. don`t want to get the phone to repair center because it will take a lot of time to be returned.
Someone had a same issue? Or if someone knows a way to fix this ?
THANK YOU IN ADVANCED !!!

Really someone ?

Have you tried a hardreset? The proximitysensor shouldnt interfere with the radio and definately not drop calls... Have you tweaked your device using an app (ie BsB or similar)?

have you tried a new radio?
Device works like this Hardware<->radio<->rom
So the radio communicates with the hardware and the rom with the radio.
So the radio commands all the hardware functions, not only the "radio" components.
So with a new radio you can have a better way off communication with the hardware and with the rom

I've just tested, and this doesn't happen to me.
However, there is an update for the radio available (actually, it's that SIM Contacts update). Did you apply it? For I didn't do that yet.
And in case you have, it would be interesting to know if others who have applied the update are facing similar problems...

Are you sure that you're not holding the phone at the bottom/back when you test the proximity sensor, I've noticed that touching this area of the phone (where the antenna is located) can have a massive difference to signal strength and in weak areas it can make you drop the call everytime.

WoW ...
Thank you for so many replies.
1st. SMUPPY - I`ve tried all official ROM`s + several cooked ROM`s + 1.61. I also tried without any applications installed, just after I make a hardreset (have made over 50 at least ). Same situation.
2nd. thomas_pieps - Now I`ll try installing ALL different radio ROM`s out there and see if anything helps. Thanks !
3rd. amang2205 - I don`t know about that SIM Contacts update ... will try and post results !
4th. Noony - I never had problems with the reception of signal at all. It happens when the signal is strong enough to drop calls. I tested it with the phone on the table, so without holding it. Immediately after covering the proximity sensor with my hand the call is dropped. So that`s not the issue here!
Thanks all again for all replies. Hope I can fix something !

UPDATE !!!!
Tried installing the hotfix and tried all different radio ROM`s out there.
SAME RESULT .... the problem still exists.
It was an obvious result because as I said previously, that happened also when using the first 1.43 ROM without installing any radio ROM`s or any other 3rd party software. Also after hard reset the result was the same. So I don`t think it`s the radio.
Just can`t figure it out. How come the proximity sensor has anything to do with the network BAND I select ?
How can that be connected ? I would make a video showing exactly where the problem is ....

This is sounding more and more like a hardware fault. The PS should not have any impact on the call connection.
You need to speak to customer support from where you bought it, and ask for a replacement. If you do this, make sure you flash the original ROM back to it

I have another (I assume) hardware issue, because I can`t turn my phone completely off. After selecting TURN OFF it just restarts, or whenever I pull out the battery and place it again the phone starts alone, without me having to press the power button.
Maybe it has something to do with the other problem ... I don`t really know.
The only solution is to go to the store I bought it from .... MAYBE it`s just that!

yep, it sounds like your phone definitely has a case of the crazies. flash back to original spl + stock rom and get a replacement.

That is *very* true. Question is: how the h*ll am I supposed to hold the phone, if covering the back with my hand causes the signal to drop?

I have another (I assume) hardware issue, because I can`t turn my phone completely off. After selecting TURN OFF it just restarts, or whenever I pull out the battery and place it again the phone starts alone, without me having to press the power button.
Maybe it has something to do with the other problem ... I don`t really know.
The only solution is to go to the store I bought it from .... MAYBE it`s just that!

I'm not an expert or anything
but it looks like you have a problem with the OFF Button. As this button responcible for turning the phone on/off and ending the calls as well..
so maybe there is an electrical problem with the phone and it glitches..
any way
good luck

Thought of that too. Maybe it`s something like that. I remember the first time I realized there is a problem ... the OFF button stopped working at all after doing something with the phone (don`t remember what, but it wasn`t anything unusual). It wasn`t functioning for couple of hours and then it started working again. After that happened I started finding problems. So maybe you`re right. Maybe it`s the electricity or something. If there is an expert with hardware around here, maybe he can tell the actual reason for why this is happening.
Strange that it has connection with the network band and with the proximity sensor. If someone had explained a problem like that to me, I would not believe that it`s true. It sounds so strange ...
