Very Strange Audio Output problem on the 2.5mm Jack

Hi,
I've noticed an audio output distortion of some frequencies when listening to music, in the sound coming out of the 2.5mm jack.
When the speakers on the device is used, there is no problem.
When I plug the headphone, there is sound output, I hear the music, but some frequencies are lowered so much that I can't hear the singers voice. When I unplug, the speakers work fine and I can hear the singer again.
In additon that, most of the background instruments can be heard as well as the backvocals, if they are female.
It's like the sound is being processed (like an equalizer) when I plug the headphone, some frequencies are lowered, given some echo, reverb etc.
I don't understand how this is possible. I am thinking of a hardware contact problem, but it's hard to believe if this is a hw problem.
I've tried two firmwares (2.16.x, 2.25.11.1) and made hard reset also. No result.
Any ideas?
Note: I can try to actually record the sound tonight if anyone wants to hear.
Best regards,
Fast

maybe try a different headset first?....could be a short in the cable, because what you are describing is a phasing issue with the headset speakers......

Thanks for the response Kiru,
Just tried a different headset plugging it into my HAMA 2.5 --> 3.5 adapter. same result.
I will try the original headphone came with the Wizard. If the source of the problem is the HAMA adaptor, this should resolve it. (i hope it is)
Could you please elaborate on the "phasing issue" ?

Hmm....how can I explain.....Let's start with the speaker itself. A speaker has two terminals on it, one postive and one negative. What we want is to have the positve from the source (ie. Amplifier) to the positive terminal of the speaker, and the same for the negative. Since there is a pair of speakers, we want them to be hooked-up correctly. If hook-up correctly then the speakers are in phase with each other, and this is called constructive interference, hence in phase. When ONLY ONE of the speakers is hooked-up backwards, we call this destructive interference, hence being out of phase. Being out of phase causes frequencies to cancel or sound muffled. Hope you kind of get what I mean, but I highly doubt that this is the problem with headphones because heaphones nowadays rarely get manufactured with this problem. This is just the electrical part of phasing. Also, you can have one speaker, and it could sound out of phase because of the distance it is firing from walls or the shape of the room due to the reflections of sound, this is called acustical phasing.
A short in the cable, meaning the positve and negative wire are somewhat touching, can cause a similar effect, and I suspect that this is problem for you. As you now state that you are using an 2.5 to 3.5 adaptor, I would agree with you that most likey you have a faulty adaptor.
Hope this helps! and keep me posted!

Hi again,
Thanks again for the explanation Kiru, I know a bit of electronics so I got the problem.
However, I'm now home and tried to original headset, no result. The same problem is existing.
This makes me believe that I've broken something inside the Wizard which shortcircuits something. I'm very dissapointed.
Maybe the only way is now to buy a stereo bluetooth headset...
Thanks for your help

Any reason that you can't return to orange for repair/replacement?

PROBLEM SOLVED
I got this unit from priceminister second hand. It's origin is not France, I don't have a purchase receipt neither.
By the way, I solved the problem. I disassambled the unit using the info given in one of the posts in the forum. I played a little with the contacts, there was oxidation in the outer solders, i cleared them up etc, it 's working at the moment.
I'll post some pictures afterwards.
and I hope i will be able to reassamble it, I already have a piece of thing which I don't know where to put

I got the same problem. Was working fine for 2 months then all of a sudden the headphone plug is all messed up. Volume is all distorted I can sometimes hear a song but quality is no where near the original. Usually everything sounds echoed. I think something is wrong with the plug

I've had the same problem. The headphone jack on the Wizard is crap. If you have your Wizard in your pocket with an adapter, as you move, the adapter pries back and forth on the jack. This breaks the cheap jack.
If you want to listen to your Wizard as an music player, you should invest in a nice set of bluetooth headphones and only plug the jack in when the wizard won't be moved around a lot, like a home or car stereo.
I recommend Nextlink Spider headphones. They double as a headset and you can navigate through your library with the button on them.

MUSIC Speed
I got the same problem here. The SE stereo btooth headset isnt yet in our place.
Anyway, i experienced this one with ROM2.16 Imate. The sound speed or music speed seems to being played faster than normal. But when i tried to plug the 2.3-3.5 adopter and quickly pull it out, the sound is played in normal speed then. strange.....

are you all sure that the wizard has a stereo output ? I thought it was mono.
Anyway you can get earpieces and headphones with a 2.5mm jack so you don't need a 2.5-3.5mm adapter.
Maybe the contacts on your jack are not connecting properly with the internal contacts of your adaptor

Headphone jack noise when nothing playing

Hi guys just curious if any of you get any squeel when using you g2 with headphones or aux when nothing is playing. Mine makes the noise but as soon as music starts it's gone. Not sure if it's my cable or car.. i don't think my Legend did this.

Never had it happen to me...

it might be engine noise. i used to have that issue a lot with other devices (my TP2 and sirius sat radio). do you have the charger plugged in when you use it

I get a bunch of annoying noise when playing music through my car speakers, but only if the phone is plugged into the charger at the same time. Not sure why. As soon as I unplug the charger the noise goes away.

thats the dredded engine noise what happens is that it picks up the noise from the battery. the only way to get rid of it is to get a filter to the aux cord. my bro hooks up systems in ppls car and it always happens when you connect it to the car battery.

+1 I got similar filter like this in my car.http://cgi.ebay.com/3-5mm-FILTER-CO...er_MP3_Player_Accessories&hash=item5d273d8ff9

Just a question, are any of you guys attaching a car charger to the phone while playing the music in the car?
Aside from zielin.

i get some feedback noise when no music is playing but when playing, there is no issue. when i stop playback, it takes a couple seconds then the noise starts. ive always had a charger plugged in too. never tried without the charger.

I get this same thing. I've never had this problem before with my G1, MyTouch Slide, Vibrant or Nexus One. It's gotta be something with the G2.

I do. I had bought a gold-plated male x male 3.5mm jack cord from Radio Shack. When nothing is playing, I get that noise.
SoTacMatt

I am bad at updating threads..
The noise was indeed caused by my alternator and only happens when the phone is plugged into the charger. The reason I never noticed it with my HTC Legend was because I used a USB cable to my car's AUX for charging. However that cable got wet and corroded so I have been using a cigarette lighter charger (igo) since then.
I installed a Parrot MKi9100 into my car and I also get the very same noise through it while navigating menus, etc. Speaking of the MKi9100, never buy one if you intend to use it for music. Parrot has messed up all their firmware and the thing is a huge waste of money if you want to bluetooth steam audio or use an ipod/iphone. It freezes all the time and no matter the source device or input, pausing and then playing again disconnects the device. It's great :S Oh and their own forums are riddled with people complaining (literally swearing and insulting the company) but Parrot seem to have NO IDEA as they don't read their own forum. They also don't reply to tech support emails sent through their own website.

yea bro i told you ya earlier it was engine noise

On my phone you can hear clicking/popping when the sound sources switch around, but I don't think that's a defect in the phone.
This thread makes me chuckle though, I have a cig lighter charger for my ipod and that never caused any weird interference issues, maybe monster shoved a filter in it? (ya.. monster.. hurray for finding it on 90% clearance at target? XD)

[Q] Playback through Car aux connection

I play audio podcasts through car's aux in and just plug in the other end to my Focus's headphone jack. I have noticed that many times the podcast suddenly lowers volume to nearly inaudible levels and happens intermittently.
Once the problem shows up if I
- play songs, the volume level is fine
- stop and start playback of podcast, the problem persists.
- unplug and continue playback on Focus' speaker, the volume level is just fine
- unplug and plug it back in and the problem goes away.
- never have this problem when playing back over headphones (when in gym)
I have this problem only with Podcasts and don't get it at all with songs or videos.
Anyone else noticed this?

Audio output sucks on this phone, that is for sure. Major issues. Sorry to hear about yours.

how so? i'm not having any problems at all.

Did any of you notice it's not your standard 35mm jack? The headphones that come with the phone are clearly deeper than the standard jack, and have two bands around it instead of the normal one.
I presume you are using standard cable to connect to car's aux jack....
I would check to see if there is a special samsung accessory to make the proprietary jack into a standard aux output?
Samsung are notorious for using this style of jack on their phones. The Galaxy line of android phones use the same jack.

that is weird. i hook mine up to my car with the same jack i used for my iphone with no problems. in fact i am under the assumption the sound quality is actually better than with the iphone.
maybe this is a canada thing?

The plug is set up to use headsets with the microphone, and may not work well with some older stereo audio cables. However, I have used it with a podcast and found it to work quite well. I suggest trying another cable, cuz the Focus works fine.

The line level output of the 3.5mm jack is approx. 40% less than that of the iphone, or my HTC Tilt2. That is the issue I have and that others have commented on.
For instance, iphone plugged in playing on my car stereo, Panteras Cemetary Gates @ 320kbps MP3 is mind boggling loud at 50% volume on the car and 100% volume on the iphone. With the Focus the car stereo volume needs to be at 90% to be equal to the volume of the iphone.
Also, since the Focus needs to be at 100% and the car stereo nearly 100% you hear the phones whining, hissing and popping and every non-music portion.
Super lame.

There's some volume problems that I've noticed on the Focus, in that it's not consistent through playback sessions and such.
The iPhone 4 uses a Cirrus Logic codec with an integrated headphone amplifier, the Focus seems to use the built-in codec with it's headphone amplifier, which might not have the same amount of oomph.
I've measured a 7-8dB lower volume on the Focus when using a line-out cable to an Audio Precision test machine.

Thanks for reporting that! Great post.

Does anyone have this problem?
Ok, I have a mp3 car adaptor that I used with my Tilt and Tilt2 without any problems. Rich sound and bass. I plugged in my Focus (just got it last night) and music only comes out one speaker.

In my '95 M3, I run an Alpine HU (9814 IIRC) with a Line in Adaptor, I run very HD (thick) gold plated lines and a Splitter (all from Monoprice.com, one goes to my portable Sirius, other pops up by my center console sunglass cubby, split happens under the passeger seat) and I usually have my 120Gb Zune attached to it, but I tried with the Phone the other day and it worked great. Played a Tool concert and it sounded as good as the Zune. Like the Zune I set the volume to about 80%, still had plenty of head room for serious volume in the Alpine. (only way to listen to Tool is LOUD!) I do run an old school Pioneer Amp, Pioneer Kevlar Components, 2 JL Audio Stealth Boxes (each is an 8" Sub).

I want to escalate this issue but I need you guys to quickly reply on the MS forums so that it gets taken seriously. Please hit the "I need an answer too" button and give some sort of descriptive reply.

I hope that his is a software side optimization since we are able to make the volume higher with the diagnostic codes.

I added my vote there.

I have a second complaint. When I stick a headphone jack in the mic turns off, it probably is expecting an inline mic with the headphones. My problem is when I then go to pull out my headphones the phone doesn't notice and will continue to not hear. It takes two or three times reinserting and pulling out the headphones to remidy this. Is anyone else haveing this issue.

Same problem here. But is worst, I connect the Focus to my Car Auxiliary jack to use it as a mega speaker, I mean, when someone calls I can hear them, but they can not hear me. The microphone is dead when I plug it in. Someone knows a fix for this?

Can't say that I have a fix for it, but it may be the connection your cable is making with the jack in the phone. I do the same thing, have the phone mounted in a jack around the same height as my head unit and people hear me fine when I speak during a call. I am currently using a cable from radioshack designed for recessed headphone jacks. Can't think of the brand off the top of my head however.

Hi pal, thanks for the reply, but I couldn't understand very well your explanation. What is a recessed headphone jack? What is the head unit?
Thanks in advance!

I have not noticed this problem however the microphone shutting off is very annoying and funny since at&t says texting while driving is unsafe yet i have to unplug my phone while driving to turn on speaker and talk. they need to fix that ASAP

Audio Distortion Under Certain Circumstances

I use my phone as an audio player quite a bit, but I've recently noticed and issue and I was wondering if anyone else had similar problems or perhaps even overcome them. When I have my Vibrant plugged in to a power source and I plug in my headphones everything sounds fine, but if I'm plugged in to power and connect a line out cable (e.g. a male to male cable for connecting to a car stereo) I get a really nasty hiss as well as other audio artifacts. I have tried numerous combinations of different power and audio cables, headphones, and audio sinks (car stereo, home stereo, computer audio in, etc.), but the result is always consistent.
Power + AUX cable = bad audio
Power + Headphones = Good audio
AUX Cable - Power = Good Audio
Has anyone else seen/solved this with their phones?

I assume you are talking about car charger and aux out and the noise that increases as your speed increases. If that's what you are talking about I get it to. Something needs to be grounded. Exactly what I don't know. I would ask a car audio person. If I'm not mistaken all radio components ie. radio amp are grounded that's why you don't hear it. Let me make this clear nothing is broken. More like this configuration was not planned for. I'm thinking the cig lighter is not grounded by car maker. Hope this helped.

In the car audio world I seem to recall some issues with Pioneer units when an owner somehow accidentally made a bad connection. It seems that a tiny fusible link in the unit would blow, and a ground loop noise would get introduced into the system. The fix was to ground the RCA cable inputs to the stereo chassis.
Not a viable solution in this case. I also recognize this may have little direct bearing on the problem, but wonder if somehow a poor power/audio connector in the unit is/has caused the same sort of problem to rear it's ugly head.
Step 1 I think - Do you have another Aux cable to test that as a poor ground on it may have developed from just bending and twisting in normal use.

Go to radio shack and pick up a ground loop isolator. That will get rid of the feedback noise.

I also have the same sound in my car. I remember way back when I thought I was a cool kid and rocked the big subwoofers in my trunk I had the same noise. Then I learned that you couldn't have the power cable running up to the battery and rca cables going to the head unit next to each other. You had to have them separated meaning one would have to go along driver side n the other along passenger side. I tried that and presto no more noise. Its the interference of electricity generated from the alternator. Hence, Faster the engine/ alternator goes, higher the noise pitch equalling more interferance due to the higher voltage/current running thru the power cable. Sorry for all that useless info lol!! Quick fix is don't have the power cable plugged in at the same time. The sound goes away, for me at least. Hope it works for you. Other than that I wouldn't really know how to fix it with a cell phone unless that isolator thingy that the other guy said to buy would work.

You should tweet @supercurio
if anyone would know, he would

This has nothing to do with software. This is basically electrical interference in audio channel because the audio is not grounded and power plug from cigarette lighter USB is grounded. Get the isolator, they are usually less than $20, just make sure all the inputs/outputs are what's compatible with your setup.
Mine plugs into AUX port on the car, then i have a 3.5mm Y splitter, one end for phone/mp3 player the other for Sat radio.

Thanks for the tips guys; I think I'll pick up an isolator and give that a try. Unfortunately, the local Radio Shack only stocks isolators for RCA jacks, not 3.5mm, so I'll have to wait at least a few more days until it gets here.

The isolator finally showed up, and it worked perfectly. Thanks again for the advice.

Sweet, now get a flux capacitor and find a straight stretch of road. At 88 mph you'll be going at 88mph with a flux capacitor!

[Q] Issue with headphone jack

Hey all. This is my first post on this forum, so forgive me if I break any rules.
So heres a breakdown of my issue. I have a samsung galaxy note 3 that I got here in korea. Im on Olleh service telecom, I believe its called. My phone model is a SM900 NK, I managed to root it with towel root, so im currently running kitkat rooted.
Though before I rooted it, I was playing music through the headphone jack to speakers via auxillary. I went to pick up my phone and as soon as I did, I heard a loud cracking noise. Now at low volumes anything through the headphone jack is outputted with an extremely static noise. To me it sounds like a resistor somewhere was blown, especially because when I turn the volume to max, the static noise is less intense. But definitely still very unlistenable
But the weirdest thing is, when I plug in the USB cable to charge it and connect the USB tether for internet on my desktop, the static noise will only play slightly when there is no audio being played (music, etc). I can even unplug the USB cable and play music normally just fine through headphones, but the issue with this is the phone will get extremely hot and begin draining the battery like crazy. Once I stop the music again itll cool off. Restarting the phone will cause the static noise to play intensly at all times again. Plugging in the USB tether again will fix this issue again, but still cause it to overheat/drain the battery. All of this is just an issue with the headphone aux jack. I can always play music through the phones speaker normally.
Last night my phone got so hot it said that the battery charging was paused because the battery was too hot
If someone knows anything about this issue that would be greatly appreciated!

Maybe you have a short in the phone:fingers-crossed: ..
anyways i wanted to ask did you try using another aux cable to your speaker?? Could be the cable itself is short.

Hope its not a short.. it could be the connector itself has gone bad. No way that i can think of to accurately check that without opening the phone..
You will have to give it to service to sort this thing i am thinking. Should be free if you are in warranty

If that's hardware issue, you may need the failed part replaced but you should check if that is software issue first, when its hot try use some process monitoring apps to see which process is causing the problem and try reset your phone to isolate any software issue.
