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 static!

Ok guys my headphones (Meelec M9P) make static when I plug them into my phone. It's starting to get really annoying. When I plug it in I hear static that gets worse when I touch the screen, but it reduces drastically when music or sound gets puts through it. My Jetblue $2 airline headphones (no mic) don't do this...
This happened on all roms, but I'm running the zomg not my dog build of Froyo.

The reason one pair of headphones does it while the other is because the one that does hear static has a lower impedence than the one that does hear static.
But the explanation behind it getting worse when you touch the screen is similar to the what sometimes happens on old PCs with cheap integrated sound. Sometimes you can hear static, and hear more when moving your mouse or when your CPU load is high. It's caused by something like signal interference within the hardware, and there's nothing that can be done... which is probably what's happening to you.
I'm using Head-Direct RE2 earphones, but the impedence is high enough that I don't hear static.
Sorry, but I think there is nothing you can do to remedy the static =/
Just did a quick search: indeed, your impedence = 16 Ohms (source), mine = 32 Ohms

This happens to me too, its really annoying and makes the phone feel like a piece of $hit!!!!

Well actually you could use a mini headphone amp like this one I have and like
Fiio E5
and it would probably solve your problem since it will be between your headphones and the phone

But don't you think it's stupid that we would need something like that?

I only have that problem when I'm plugged into the car charger. DC vs AC I guess.

actually AC is noisier. it has a sine wave, DC does not. your wall charger still spits out the same DC as the car charger, it just rectifies the ac to dc before stepping the voltage down. Car charger is all dc so its just stepping the voltage down from 12v to 5v. car charger probably has a weaker ground. Most car chargers I've seen are poorly built...

i thought that was normal
i got some sony MDR-V150's and i get that **** too yes i know they're old! so dont say anythin bout that
its not very loud but since i got good hearing plus the fact its right on my ears i can hear it when nothin is playin or when i touch the screen

Question for you guys: why do you put headphones on when music is not playing

I'm using M9P's, and they use a mic so I can take calls with them also, and I love using voice command with them .
Ahhhh the impedence problems seems right, but I wonder what the impedence on crappy airplane (Jetblue) headphones are then? I think it might have something to do with the mic, but there were ways that would slow it down. I could "turn" on the headphones without plugging it in through an app called toggle headset. It removed a lot of static, but sometimes it didn't work...
All of meelecs phones' are 16impednece, which makes me believe that when I get my m11+'s they'll have the same prob

No headphone pop or capacitive screen static
The static with touch screen issue has been addressed. It was a problem with any OC Kernel, but it has been fixed with the latest kernels Darch has been putting out.
CyanogenMod RC1

[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] Aux Output on N9005 (SG Note 3)

I have tried every search term I can come up with and short of going through every post in the Q/A on the Note 3 I can't find a definitive answer on this one.
I have noticed many other devices have the same or similar problems
I am trying to use my device to play to a car radio via an Aux cable, without much luck. It has a constant humming in the background, I have tried it with a few cables and a FM Transmitter and get the same results.
No issues with headphones at all
Humming only when it is plugged into the charger, very quiet (Nearly silent) if not plugged into the charger
Tried many different combinations of cables and chargers
Is there an easy fix?
One alternative I am looking for an A2DP - FM Transmitter but it has to be USB powered as I have a 5 port charger in the car, all the ones I have seen is powered direct from the power socket. I have used A2DP direct to another car radio and it works clear as day which is why I am exploring this option, as well as the ability to skip tracks from the remote control.

I use my Sony Bluetooth handsfree for that. It works like a dream. The only issue is charging: older models can't connect to phone while charging. You should check this before you buy your BT handsfree.

Do you hear that humming when phone is plugged to charger, but engine is not running?
Does the humming change voice or get louder with higher RPM? This is pretty normal on cars that phones keep noise when playing music through AUX while charging.
So most probably your car alternator causes this. One possible way _might_ be to ground your cigarette lighter 12V(?) output from car straight to battery or/and put something between + cable that gives 12.0V to your phone charger, no more no less, since every car I have had the voltage on cigarette lighter depends on RPM. While engine off it gives what battery has (~12V) and when engine running on high RPM ~14.5V
One more way would be grounding your phone to your car, but that might be a bit hard, and I don't know would it do something bad to phone either lol
Hope this helps.

I remember a similar issue occurring a long time ago. Had to do with the screen brightness being turned down.
Does the problem also occur if you set the brightness to 100%?
