Hi, I have recently bought a Zte blade a475 and everything is fine except for one thing and that thing is the very very low volume coming from the output jack when you connect an external device like a car stereo for example, but if i connect the headset everything is fine so i knew something weird was happening there so i decided to find out the problem.
when i connect the phone to an external speaker and press play in the music app i can hear a weird sound like a "plop" just before the music starts and then the volume goes down to almost 0, but when i connect the headset (headphones and mic) everything its fine and no "plop" sound so i realize that must be a software problem.
Also if you connect the aux cable just the half of the connector it detects the cable as a headset then insert the connector all the way down and everything plays just fine with no "plop" sound before the music starts but is annoying to do that all the time so heres the solution.
FIX:
This may work in other zte or chinese phones.
1.- Go to enginer mode: to do that dial *#*#3646633#*#* then go to hardware testing, select audio, select Headset Mode
In type go to media and Set the Max Vol. 0~160 to 104 and set
thats all !!!
Tell me if it works for you
Thanks Heaps
My A475 is doing this same thing when my volume is set at full, this fixed the problem.

Hello,
i have a problem with my device: it has stopped to make sounds (as the click on selections, the music from a mp3, the ring of a call) i can hear the voice of the speaker in a phone call. But i can listen to everything if i put the headset on. It seems like the device is switched in "headset mode" turning off the main speaker. When i plug and unplug the headset i can hear (sometimes) the sound to come back, just to shut off the second later.
I've tried soft and hard reset and i've even installed the news rom: once installed it seems to work properly.. but this morning is "mute" again..
anyone would help this poor guy?
thanks in advance!
Execus me for this question, but I have to exclude the obvious. Did you try raising the volume utilizing the speaker icon on the top bar?
The volume is at the max and all the sounds are enabled.

Are you using any siftware which might conflict with the OS?
Test the volume with no software installed and BOTH sliders at the maximum (UP)position,also bear in mind that the installed windows media player has a volume slider of its own.
Sadly not: the problem is still there even after an hardware reset, without any other software installed. And if i plug the headset i can hear everything, so the volume is up.
It seems like the device is finding the headset even if they are not plugged, thus turning the main speaker off.
...maybe a broken loudspeaker...
I'm afraid to say this , but before to have my trinity I experienced a similar problem with my old JAMin , were the loudspeaker suddenly stopped working and only with a new one ( loudspeaker) I recovered the correct " voice" of the device.
in this case it seems to be the same , but to be sure you should be able to mesure the impedance of it ; normally should be around 30 ohms ...
when mine was broken , it was completely "open" ....
but to do this you have to open the device !!!!
I'm sorry , any other idea...

From what you say i think we can safely rule out the loudspeaker being damaged(you wouldn't have been able to hear anything ,not even for a second), it's more than likely that your problem has to do with the miniusb audiojack which might be shorting out,the only thing you can do before taking the device to a service center is insert a miniusb cable in the jack and carefully move it sideways and up and down,this might resolve the issue.

And... sucking the jack... although this might gives a too strong picture of how much you love your trinity
Thanks a lot,
moving the jack seems to solve the issue sometimes..
I was wondering: are there any settings on the registry to avoid the use of the headset: maybe if i can set the device to never use the headset the problem with the switch could be bypassed...
lost sound
well my trinity just did the same thing.
Was working fine one minute, then suddenly no sound. Plug in the headset and it works fine, but without the headset I can connect to a call but i can not hear the other person and strangely they cannot hear me. Seems like my phone is stuck in headset mode somehow.
Haven't done a hardrest yet, but i guess thats next . . .
I have no idea what caused this (no drops recently) but would REALLY appreciate some help as my phone is really useless at the moment.
Presently, absolutely NO sound comes out of my phone at any point, via speakers or headphones, except during calls, where i can hear the other person but they cant hear me, i.e. microphone isnt functioning.
I have no idea what causes this, I have done a hard reset and inserted and removed headphones many times.
I should clarify that by absolutely no sound, I mean nothing on the phone works sound wise. You can in fact hear a really faint clicking/popping sound occasionally, but its grey noise, its not really quiet versions of what the sound is meant to be.
Many thanks if anyone can help!
I also made a brief voice recording on the phone and copied it to my PC to find it was blank, so microphone doesnt work outside of a call either.
.. summary: mic broken, speakers only work in a call.
Help?
Bump! Please?
try pairing with a bluetooth headset, you should be ok ... seems your sound driver is corrupt, did you by any chance increrase the preamp a lot in tcpmp and play sound for a while before experiencing this?
Cheers for the reply!
I hadn't done anything out of the ordinary like you mentioned, it just stopped working. I have done a hard reset, wouldnt that sort out a bad sound driver?
And, as far as I know I have no access to a bluetooth headset, why would that be any different anyway?
Is there any chance a rom reflash could help? I'm at last resorts here, I'm thinking about buying a palm!! (for budget reasons)
I will try it if it could work, trouble is the usb port is very dodgy, dis- and re-connects very often, so that could be dodgy for a reflash?
:'( !!
also mine is off!! just hearphone works, but built-in speakers are dead!
PLEASEEE help me!!
same problem occured to me...
if you were using a normal headset and after you plugged it out the sound started to break apart then do the following:
1-turn your media player on and start playing any audio file while volume is at MAX...
2-try to plug it in first and then test if the sound comes out of the headset normally...
3-then plug the heasdset out of the device (not all of it keep some of the jack inside the headset hole) do that in slow motion....yes...in slow motion and try to focus in making the sound goes out of the headset and the device at the sametime....
4-if you managed to make the sound BLOWS OUT from the speakers then the problem is because you plugged out the headset too quickly which generated a shock (actually i dont know if that's the accurate definition)
5- try to twist the headset jack left and right and plug it out gentely while the sound is still going out of the speakers...
and thats it...
hope your device will get well soon

I did steps you mentioned and get my sound back!!
Thank you wizzmaster..!
Hey odd question, lately when I plug in speakers or a tape deck adapter to my HD 2, it will close out whatever program switch to music, then it will cycle music like crazy. Kinda like if its getting a signal to switch tracks etc. Anyone know what could be causing this? Using Energy Rom.
Because the HD2 uses a headset with media controls, and most likely it is getting false signals from your speakers, also the headset jack is a microphone jack not just speakers, you cannot just plug stereo speakers into a jack that has contacts for , controls, mic , and sound ...
Thats odd when you say that tho.. cause I use use Nokia MD 4 (With the FM ant able in the cord) http://www.newegg.com/Product/Produ...9&cm_re=nokia_speakers-_-75-975-079-_-Product
The HD2 works fine.. just anything else messes it up. So what is everyone using in the car and so?
I plug my FM transmitter into the headphone socket in the car,and use
2 different types of headphones,a generic in ear set and some
folding Sennheisers,neither give me any issues,they just work....
I use a set of travel speakers plugged straight into the HD2 speaker jack & everything runs fine.
I plug it into my stereo and it works 100%
I sometimes get the crazy behaviorwith common headphones. It's fine 99% of the time, but sometimes in the pocket the plug will start doing some bad contacts, and then it starts switching tracks, or even calling the last number...
Need to remove the headphones, wait a moment till it processes the ton of "false commands" that were sent, and plug again. Sometimes a reboot is needed too.
Youd think there could be a fix or on cooked roms a way to disable inputs from the headphone socket.
I guess I should have been a little clearer what I said, ...
and yes I typed it hard to understand ....
Some speakers work, some don't , some will give you false inputs, others will not ....
Most small portable speakers will not ...
I tested this theory just a little while ago ...
My regular headset from my mp3 player works fine ...
1 out of 2 sets of computer speakers I have makes my HD2 freak out ...
I tried my travel speakers again and they were fine, so I have tried my brothers portable speakers that are a different make, they too work fine. I have just tried it with my big house speakers and again fine.
Thinking about it, my Omnia & my HTC P3600 both came with headphones that had a microphone & control buttons on & I never had any problem plugging them into any speakers, same as I don't with my HD2 so I'm sure it can't be the phone & must be a rom issue or something like that I guess.
Sorry I can't be more helpful with an answer, but hopefully the tests I've just done will help in some way.
I am using sony XBA-H3 , which has two kind of lines
one is with mic, four channel plug. Another is without mic, three channel plug
this solution is just for three channel plug headphones
Everything you need to do is play your music first, and then plug in your headphone which has three channel plug
the phone will detect as audio out put bet headphone(look at the small icon on the notification bar)
and then, you will find that
AMAZINGLY, THE HISSING SOUND DISAPPEARED
So, i think the issue might come from some audio process for headphone only?
But, at least, we finally got a way to listen to music on our G3
edit
you need to plug your headphone very slowly that it could be identified as audio out put
I have Bose QuietComfort 25 wired headphones. Anyone else use them and have problems?
1. As soon as I plug them in to the phone and adapter, the ring volume immediately goes to vibrate.
2. The in-line microphone is not working.
3. The in-line buttons seem to provide random results on the phone, usually any button just ends up lowering the media volume.
4. After plugging in the head phones, the power button no longer turns off the screen until i press volume up and volume down on the phone.... ?????
Audio through headphones works just fine though.
Not tried them with this phone myself. Sounds like a pinout issue, like you would need a CTIA/ OMTP adaptor. Although after trying to look to see which it is, I'm seeing lots of places selling an official BOSE android compatible cable. So I guess getting a new cable, while not great, is your best option.
Try shutting down, plugging in the headphones and restarting.
