Muffled sound on XDAII

Hi All,
I bought an XDAII about 2 weeks ago and am very please with it, however, when I make and receive calls, the sound seems to be very muffled. The people I call also comment that I sound very muffled too. Is there something wrong with it, or is this usual ? I was also wondering if a Radio Stack upgrade may cure this problem.
Here are my current versions etc.
ROM Version 1.03.00 USA
ROM Date 09/24/03
Radio Version 1.05.12
Protocol Version 1337.12
Any help appreciated.
Thanks,
Rob.
unfortunately it doesnt.
i know what you mean . . . but i upgraded my radio stack to 1.10 and it's still the same sound
i just hope it's just a setting of how the audio is decoded by the radio (sort of like the nokia setting you can turn on and off (at the expense of battery power) forgot what it's called.
cuz if it's not that, then it just means it's got a lousy speaker hehehe
hehe.. Thanks for the reply mate. At least I'm not the only one with a muffly speaker n mic
Ta,
Rob.
no prob :wink:
i think everybody has the same problem, only they just dont think it's a biggie (or aren't as picky as us) since the audio STILL is intelligible anyways
Has anyone else encountered a problem when either using the phone normally or through the speakerphone option, there is a slight rattling when the volume's set high?
This is quite annoying if common and is something other speakerphone phones seem to suffer from.

XDA2 not as good as it looks
Hi there
I have my XDA2 for 5 months and I´m in love with it, whenever one of my freinds mention its faults I get upset :?
But, we all know that the XDA2 is FAULTY big time, sofware not well developed yet, and yes, we think twice about buying software (same apply to hardware)
I have learn how to live with all this, still think that the XDA2 is a top tool for work and everyday life and I hope that other machines come to the market to compete, then we will get value for money
Bad Sound Quality
Hi,
I also bought a MDA II (T-Mobile Germany) some weeks ago. I really like it, but I also think that the sound quality is not the best. There are two effects that annoy me:
1. I can hear a high pitched beep in the speaker, always when the device is switched on (not only when talking on the phone but always if it is switched on). It is not very loud, but I can hear it clearly in quiet environment (my ears are still too good I think...).
2. The sound has to much "base" and to less "treble". Well, you can understand the person on the other end but this is definitly the worst sound quality I ever had on a phone.
This is the only thread I could find discussing this problem, leading me to the conclusion that either most phones are good and I got a bad one or most people don't bother if a very expensive phone sounds like a $5 toy...
Is there a chance to get a better sounding replacement phone or should I learn to be happy with it?
Regards,
Oli
Sounds Rubbish
Hi guys
i noticed the sound isn't as good as the XDA I when playing mP3's or MPG files on it.
does anyone know if there is anything that can be done to correct this ??
other than buying a set of speakers to go with it, doesn't seem much else ! ;(
any solution for this???????
I've got the same problem, however I've noticed that the sound is clear when I use the XDA 2 with my tomtom navigator the voice instructions are very clear, its strange + when I use the speaker phone the other party can hardly hear me.
sorry to tell you this, but i have got mine repaired and strange that they changed the motherboard to get rid of this problem, means it is a mother board problem not speaker or software.

Click to expand...
Click to collapse
The high pitched beep is caused by the poor filtering of the power electronics of the background lightning of the touchscreen. It is worse if the light is set to low. If you set it one or two notches higher, the beep sound will go away (or at least you won't hear it anymore).

Metallic sound from the speaker...

Hi guys.
I have a little audio problem with my Himalaya/i-mate/XDA II/MDA II/Qtek 2020 or whatever you like to call it.
The internal speaker seems to have a contact with something metallic or hard plastic. At the max earpiece volume, when calling, the ringing tone is distorted. When lowering the volume, it does not do this. It seems that, when the plastic membrane is moving, to reproduces the loud sound, it touches something hard and it distorts the sound. Does anyone have experienced this? I want to try to fix this. I paid hard won money for this marvellous device, and I do not want my experience to be ruined by bad audio.
Thanks for the help guys!
Not sure if its the same thing but when i played any sound it crakled a little. Did not bother me until the camera sound went on and off every 1 second. Did a hard reset and seemed ok until it happened again so i did another hardware reset went through all the programs i had instaled until it happened again. So i reset a third time without instaling that program(cant remember the name of it) but it works ok now.
I know what you mean Patrick..and if you hold your thumb over the earpiece it sounds a bit better, though of course muffled.
This is something that does bother me as I sometimes use the loudspeaker call option. Other phones don't have this problem in loudspeaker and it surprises me the II does this, as apart from a slightly rattly volume adjuster the build of my II is significantly better than the XDAI.
Just one of those things we have to put up with in order to have such an otherwise great piece of kit, though I'm equally surprised the manufacturers didn't notice it!

Thanks a lot !
Yeah, your description and the thumb thing is exactly what I mean. I wonder if it's the speaker membrane itself or a contact with something? Maybe it could be fixed?
Thanks a lot guys!
It may be a warranty claim, you need full volume when using the speakerphone, get in touch with the service centre.
I have the same exact problem... The sound distorts if you have it set too loud.
I guess it's just the el cheapo speaker or poor design.
Hi guys, i have the same problem and its bugging me alot, any sugesstion or solution???? is it a hardware problem or did we install some software that case this? my XDAII still has warranty do you sugest me to go for service center or just live with this problem.
Thanks
Well Iam not saying its a good thing but Iam happy to see Iam not the only one experiencing this problem with the speaker although I dont own XDA II but XDA IIi or Qtek2020i whatever way you wanna call it. I also wondered if it is a harware problem couldn't we replace the speaker with a better quality one? In my case this jitter mettalic sound does not happen only in speaker mode but also in normal mode as long as the volume is set close to max or max.
My Qtek2020i has the metallic sound only when it's a large amount of humidity and very hot outside.
It seems that the speaker suffer a lot from humidity, it also happen when i keep it in my jeans pocket and i prespire a lot. After half an hour when it dries out, everything is ok.

Is the sound problem hardwer or softwer issue ?

ok .. i like my x10
but i always ask about this issue is it hardwer or softwer
can any one help .. .
thx
software issue
When you say sound do you mean call sound and the Mic picking up lots of background noise? That seems to be a big thing for me and its quite bothersome
Sent from my X10i using XDA App
The sound on mine is horrible too. I really hope it is software but I have a hard time seeing that being true.
I always get told how bad it sounds when I talk to people on it, sounds fuzzy apparently and I always have a hard time hearing people some times.
Please be software!
i mean by sound of the x10
te general sound
for me i care about the headphone or when i use the phone aux with my car
and ply some music the sound is low .. to low
even when i walk around with earjaks .. i can hear everything around even if the level is the most ....
so i hope its softwer thing
Yeah that is also a bad feature of the phone. You'd think Sony would have tried to incorporate their Walkman expertise in this.. but yet Walkman isn't even a name anymore. Just forgotten.
Also if you put the volume too high it gets crackily.
The problem can be either software or hardware. If the DAC they have has terrible resolution or their algorithm for sound isn't up to the task the sound will be bad. Or even under-driving the speakers.
But anyway, I've noticed the in-call speaker for the x10 is very directional, meaning it doesn't let sound radiate out from what I can tell. This might sound silly, but it worked/works for me, just slide the phone around on your ear a bit until you find a "sweet spot" that maximizes the sound.
Mine was relatively low before but now I can hear pretty well. With that said the volume is still pretty low regardless.
EDIT: The x10 uses a separate speaker for audio while not in call, its located at the top left side of the phone. This speaker probably suffers from the same problem as the other one. Except this one is made to radiate.

[Q] all audio sound is off. please help !

hello everyone ,
suddenly i have face a problem. my all audio sound is off... i can hear call sound... music player sound, video player sound, headphone sound and everything .
i have check acceptability turn off all sound if unchecked . then i do heard reset. after that problem is same :'( what can i do now? please help me.
U dont really make sence there but what i understand is you have no audio at all even after re flashing software?
If thats true then probably your audio IC needs reballing or in worst case replaced.
This problem can occur when you drop your phone, if not then i would sent it for warranty and claim a faulty logic board.

Galaxy s4 has no sound what so ever!

Hi guys, so I have a cricket galaxy s4 (old cricket), and it has no sound what so ever whether it be from the main speaker, ear peace, or if I put earphones into the headphone jack. The microphones don't work either when sound is gone, and I'm wondering why this is. I don't think it's a software issue because no matter if I flash to another rom I still get no sound but I may be wrong. The audio sometimes works like normal , and when the audio comes back the micrphones start working again but then it goes away if it's like shaken or something. So can you guys help me out? I'm not sure if this is some deep software problem or a hardware problem (think it might be charging port?), hopefully you guys can help out thanks.
The best way to troubleshoot this problem is to completely restore your phone to stock and then, if the problem persist, it's most likely an hardware defect or a bad contact between the motherboard and components
