Problems With Low Sound Limiting? (CM10 on SG2 GT-i9100) - Galaxy S II Q&A, Help & Troubleshooting

So I've spent a great deal of time troubleshooting with the TriggerTrap (triggertrap dot com) support about this and we can't find a solution.
I'm wondering if the mod is the problem.
The app works by sending out a high pitched sound through the headphone jack, into a dongle, which converts that sound into a trigger, basically, which fires your DSLR.
Problem is... I can't get it to fire.
Now, without the dongle plugged in (which plugs into the headphone jack), I can hear the high pitched noise completely fine, but when I plug the dongle in - it's not picking up the tone.
Through tests, it's become apparent that the dongle isn't broken or anything.
So what I'm thinking is, is the sound being limited when being put into "headphone mode", if such a thing happens?

Bump here... really need help. :/

Were you able to solve this? I also have this hardware now ... But all my androids won't fire up my Pentax K5

[Q] 3.5" Headphones

Hi.
This is my first Samsung so, have mercy
None of my headphones are working.
I only get sound in one side and the other is too low. Almost inexistent.
I tried with cable to connect it to my audio system and the same.
Next step was to use the hands free from my X10.
Is working ... but not as expected. Almost no bass and no trebles.
The only ones working are the ones from the SGS2 box or using my headphones via MW600 bluetooth (which i don't like it as it drains more batter and the SGS2 is power hungry)
So, is a problem with the 3.5" ?
Or my headphones?
Or ... is a compatibility problem? Can i find somewhere an 3.5" adapter?
Thanks
Its gonna sound dumb but u have plugged the jack all the way in yeah? Takes a little bit more force than u think

Worked with other headsets for me
- Dell streak headset
-Iphone headset
Needed that extra push to fit the pin in really well
Well, i'll try one more time ... anyway, earlier i found something else using the X10 headset.
If i press the "answer" button from headset, everything is fine but as soon as is de-pressed ... it goes back.
I have a similar problem with my expensive Shure earphones. They sound much worst and "tinny" then the standard earphones that come with the S2. Even if these earphones are cheap, at least the sound is acceptable.
If I plug the output of the S2 into my car stereo, I again have terrible sound. I am not sure if this has anything to do with the fact that the stock S2 earphones have 4 contacts on the jackplug as compared to 3 on normal jackplugs. The extra contact, I presume, is to permit the switch for fast forward to work on the headphones.
I can't understand why other people don't have this problem - and yes the jack plug is pushed right in.
Yep, pretty sure, the jack is down entirely and still not working.
I tried with the SE X10 headset and normal stereo headphones
I think i will have to stick with the bluetooth if i can't find an adapter of some sorts.

sound noise

Hello everyone
I just got my archos 80 g9 turbo and I am really happy for the price.
But unfortunately I have a problem with the sound. If nothing makes a sound for some time , the sound becomes distorded like white noise. If I change the volume the sound is fixed until is silent for a while and becomes distorted again.
I tried re initialize everything as it seems to me like a software problem but no luck.
Anyone had the same problem ?
Edit: I think it is completely random when noise starts. But after sometime just stops....

Hey buddy,
i've got the same problem with my just bought Archos G9 101 Turbo.
Sometimes there comes a crackling noise out of the speakers. Sounds a bit like an old reeeally dusty vinyl record...
Is there any solution available?
I tried many software wise tweaks to solve the problem, nothing worked. So i rma it and hey send me a new one. Even the new does it but much less so i can live with it.
I have seen 3 archos 80g9 and all of them had the same problem ,so i believe its a design flaw...

I am on my second Archos G9 101 250GB Turbo. I returned the first one because of random crackling noise from the speakers (and for the phantom screen clicks). Both problems still exist on my replacement device. The noise occurs at random times for a few seconds then stops. I have noticed that it only occurs when the WiFi is on.
I use the Archos solely in the car as a media player (connected to my stereo via aux-in) for hours on end without ever getting the crackling noise, yet when I get home and connect to the WiFi…there is the noise again. I am not sure if this is software or a hardware issue.
I can live with this though because it works flawlessly as a first rate car stereo.
Yes, there are differences unit to unit. What I observed that the 2 units that came out of the box with honeycomb had this issue much more than the one that came with ics.
I am not sure if it is hardware or software either, my impression is still that is software because it is audible from phones and also looks like the crackling noise continues until the stream is over.
For example:
You play an mp3 and it starts with crackling sound.
The sound continues to be crackling until everything is silenced for a couple seconds
Then everything is normal.
But it appears to be random (haven't test with wifi turned off, I use it all the time with on ).
If some dev can check sources for solution or identify the problem I would be thankful

I have not heard the crackle noise on my Archos for a about two weeks now. I use it as a media player (mp3) two hours a day everyday in the car. The Archos is in a dock on the car dashboard connected to my car stereo via Aux-in, I hardly ever hold it in my hands
The Archos 10i G9 Turbo is totally standard OS wise. I have replaced the original 250GB HDD with a 512GB SSD and because I only use it as an MP3 player and nothing else; I have disabled every application I was able to. I no longer use Bluetooth or WiFi.
I suspect it may have something to do with (based on my observation only and not on scientific basis):
1) WiFi connection?
2) Holding it?
3) Use of internal speakers?
4) Heat?
5) Software?

1) in my case no
2) in my case no
3) the problem is only with internal speaker
4) I'm not sure but it may be .........
5) with diferents rooms seems that the same, I'm not sure, so I asked
I think the problem is impedances, but the device that causes the problem is........?????
if the reason is this design flaw and not well protected the speaker.
Are speculations but together we can get something clear
Someone else with the same problem can describe when it happens what is doing?
Thx.
My first g9 did it everywhere, mp3, youtube , browser, games... and it was totally random in my opinion (i didnt check wifi on -off ). Very very very irritating.
I suggest you to rma yours like i did mine.
Btw with what android version your tablet came?
Sent from my ARCHOS 80G9 using XDA Premium HD app
4.0.6, upgrade to 4.0.7, rooted and now with [email protected] V3.
I just got a G9 80 with v4.06 on it. If it's plugged to the charger & charging, the electrical garbed sound will be there when typing or upon playing music/videos. If the charger is not plugged it, the garbed sound is intermittent when playing sound.
Seems like faulty hardware or a design flaw to me.
I will try the following when I reach home later:
1) upgrade to 4.07 & test
2) Test with earphones inserted
Results:
1) upgrade to 4.07 & test (same issue )
2) Test with earphones inserted (clean sound playback, so it's the speaker only.)
I found out something upon inserting a usb thumbdrive to the G9. I have no sound garbed when the thumbdrive is inserted & enabled.
This is true for games & music, but when playing videos (Big Buck Bunny), sometimes the problem is still there. The inserted thumbdrive seems to reduce the frequency of garbed sound.
Can it be a grounding issue?
Hi
Everything you say makes me think the same thing, shielding is the problem, i do not know if the speaker or cables are not well insulated.
I think the key word here is impedances, with good insulation could be solved.
I not have so much electronic knowledge to fix it.
some electronic some out there who can help us ??????

[Q] External microphone , Is it possible?

Hi
At the moment im in the planning stages of doing a Nexus 7 headunit for my car.
What I have planned at the moment is for the nexus 7 and the S3 to be running tablet talk.
This allows the called id to be displayed on the nexus whilst the phone still does the calls.
What i wanted to do was have my S3 and nexus 7 plugged in via splitter to the aux to my radio
This will allow the S3 call to be played on the car speakers aswell as the audio from the Nexus 7.
When i receive a call the nexus 7 audio mutes and the S3 can continue to route audio to the car
Is there such an adapter that will allow the audio to pass through and allow me to plug in a small microphone?
Like how the normal headphones work with built in mic.
I would like the same sort of thing, where as the phone call is routed through the headset jack and to the car speakers, and if i add a microphone as well so that i can have the phone in the arm rest hidden and use a better microphone near the windscreen just like a normal bluetooth handsfree kit does.
If anyone can help i would really appreciate it, As this will solve alot of problems for me
Edit:

Audio qulity from headphone jack

Just wanted to know if anyone else noticed faint buzzing/scratching/hissing noises coming out of their headphone jack...
(and yes I have tested several headphones/earbuds and tested with my MDRv6's all with the same results. Its definitely the phone not the headphones)
When I insert my headphones there is a quick beeping sound that plays for a second or so then goes quiet.
When music is playing, especially soft music (a particular song was Instant Crush; Daft Punk) there is a hiss in the background, specifically when certain tones play.
It was terribly noticeable right at the beginning of a few songs, especially the one I listed above.
I also have button sound effects enabled. So When I press one of the soft UI buttons it makes a tick noise. However for about 5 seconds after the tick there is a long hiss then silence until I press another button.
The volume of the hissing/scratching noises is directly related to the actual volume of the device and the note playing.
Im on stock build 11c w/root, and I havent found a lot of info about this problem.
Just wondering if anyone has noticed this, or if this is a known issue?
If your phone is warranteed, I would bring it in
The G3 boasts an AMPLIFIED 1 watt sound speaker, which means there is a powered sound processor.. Unless the jack needs to be cleaned, I would lean toward thinking there is a defect in your phones jack, or sound assembly. I think its more than likely a defective jack, especially if there are no sounds like you are describing when headphones are not in use
Yeah the phone is brand new. I think I'm going to RMA....

Just got my G3 a week ago and didnt use headphones until I read your post, I tested many different songs with different players, stock player, google player, Iheart radio, pandora, etc, headphone sound is crystal clear on mine, I dont get any beeps either like you described, I did notice you need to make sure the jack is pushed in good and tight, I put it in and thought it was all the way in and sound was crappy, pushed a bit harder and it clicked in good and sound was great, do you have a case that may be preventing the jack from being pushed in all the way, I had a phone in the past that this happened to me with, had to cut away some rubber on the jack to make it fit snug, if none of those are the issue, I would look into a warranty claim. I am using the beats audio earbuds that came with my HTC M7 I had before this phone.

That could be the issue. I know on the 2012 Nexus 7, it's really bad. It's supposedly due to the microUSB port and the headphone jack sharing the same circuit, or some engineering thing like.
Wonder if it's the same or if they didn't shield the headphone jack very well and it's picking up interference from the microUSB port when charging?
I didn't want to leave this up in the air so I figured I would post an update.
I replaced my G3 through Verizon for a brand new unit. My first phone was of an earlier batch (came with the 10b update) the second one was of a later batch and had 11b pre-installed.
Both phones had the same issue. There is a hissing noise/distortion that comes from the headphone jack. Even when not playing music.
I noticed it on other phones too but not anywhere nearly as much. I understand that any audio source is going to have a little background interference but the G3 definitely has a more significant issue than others.
However it seems to be entirely dependant on what headphones you are using.
1st. I tested first with my Sony MDR-v6's which the problem is most noticeable on. Extreme hissing/background noise.
2nd. Then I used a pair of Audio Techina ATH-PRO500's and the problem was almost unnoticeable.
3rd. I also tried my Steel Series Siberia v2's and the problem was again almost completely gone.
4th. I also used my receiver at home. JVC 5.1 channel receiver with RCA speakers and a Kenwood sub, didn't notice the issue at all. However there where some occasional strange popping noises when no music was playing I didn't get on my GS3 or other MP3 player.
5th. Finally I tried the ear buds that came with my Galaxy S3 and the distortion was again totally noticeable with and without music playing.
This is most definitely an issue that totally depends on what headphones you are using not sure if it has to do with sensitivity or impedance (this is what most people think) however it is most definitely an issue. I saw a few threads saying that audio issues were a problem in Android 4.4.2 however LG/Verizon have yet to release a stock base on anything but.
I suppose I could flash AOSP 4.4.4 and see if the problem persists but I don't know if that would even be worth it.
2 phones and 4 headsets later this is starting to seem like either a software or a design issue.
However I have nothing but good to say about every other bit of this phone. Really besides the audio jack top notch all around.

I might have found a workaround for this
I have tested 3 LG D855 and all of them have noise/static/high-freq leak from the processor out to the headphones. It might be a faulty design for the headphones amplification stage for headphones (when the headphones logo appears on the status bar). However, when using line level output (the jack appears on the status bar) the problem does not reproduce.
Therefore the workaround I've found is to trick the phone into line level output mode and then plug the headphones. To do this you need to plug in a 3.5mm jack extensor or a 2-to-1 3.5mm Y-adapter with no load, that's it, with nothing connected to it. At that moment, the phone will activate the line level output mode. Only after that you will connect the headphones, and you'll see there are no artifacts on the audio.
That being said, I'm not sure this will work with all kind of headphones as I have only tried with mines that are low-impedance ones, but on those it works perfectly. To be checked if the level of the signal in line mode is enough to drive other headphones.
In any case, it is a shame this happens with a high-end and expensive smartphone. I was hopping this will be fixed in a newer hardware revision but I got two replacements of mine and no luck. I have read somewhere this might be a flaw in Snapdragon 801, as it integrates completely the signal routings but isolates badly highfreq noise from processor stages, etc. etc. but I do not remember where I did read it unfortunately.
I hope this helps!

Ive been having the same issue. I have a pair of Shure SE846 which are about 8ohms. I experience the poor audio, especially the noise in the left channel. I find that placing a call and then listening to music removes the left channel static but the sound is still kinda bad. Ill try your suggestion tonight and post back. Just wanted to let you know your not alone.
I despise my G3 because of this. Im looking to get a new phone unless I can fix this.
Nope, my sound is perfect on my high-end Sony over the ear phones. Crystal clear on pure stock G3 .
I haven't noticed any artifact issues on my phone when using headphones, however when I plug it into my vehicle and also plug in the charger that causes everything to go nuts. The USB interference causes a crazy amount of excess noise. I haven't ever actually tried listening to headphones while charging, so in the car is the only time I've ever noticed it. The same issue occurs when I plug in my Galaxy Tab Pro into the aux jack and charge it at the same time, so this is definitely not unique to the G3. I wish all phones had as good an amplifier as my HTC DNA does, I still use that thing for music because the sound is so good.

I'm having a different audio problem.
With headphones plugged in and listening to music using any player, the right side sound emits distortion/hissing noise at a certain frequencies. When I tested it with plugging a 3.5mm to 3.5mm to an external amp (JDS labs c5) the distortion/hissing noise is completely gone. So it's definitely not a faulty jack
The hissing is evident at the beginning of (first few seconds) Tina Area's Still Running and You set fire to my heart .
I'm testing it with sensitive iem (Westone Um3x).
So does this mean there is a problem with the internal amp of the g3 or more to do with the os bug that can be solved with a custom kernel or update.
Is this a common issue found on all g3s?

Hi! This worked perfectly for me but for me instead of tricking the phone into line level output mode, I detaching one side of my headphones before plugging it into the headphone jack then reattached it afterwards. I'm using pair of sensitive iems (Westone um3x rc)
Everything is quit with no distortion, just how it should be!
One thing, is there an option within android or an app that can permanently enable line level mode ever time headphones are plugged in without having to trick it.
If so, I won't have to sent my phone for repair!
Also are there any disadvantages for using line level with headphones?

Using line out shouldn't make any difference on audio quality. It only disables the remote (buttons and microphone).
Would also really like a way to force the line-out mode. Btw, does this affect all G3s? Cause right now I'm not sure if it's worth the hassle of replacing it.

I know but some how using line out causes the hissing from the right side to go away completely. Strange huh
Are you also having this problem?
I also don't want to return mine if it exists in all g3s and there's a easier work around.
Yea same thing. I have artifacts in the left channel except when I manage to force the phone to recognize the headphones as line-out. I did this with the adapter to test it and it's impractical if not impossible to use the same adapter all the time.

I don't use earphones with a volume remote or microphone so that's not a problem.
It could be more to do with the increase in output impedance but I might be wrong cos the volume level is identical to headphone out.
I'm also getting a lot of static background noise but it disappears after making and hanging up a call as mentioned in a thread.
But yeah a permanent fix by forcing it into line out or doing some changes in kernel would be much more convenient

Hissing/ 'SSSS' sound from Redmi Note 3 Speaker and When Connected to Amplifiers

Hey Guys.
I'm creating this thread since I did not find any other old thread about this issue.
When a song or any audio output is done through the Redmi Note 3's Speaker or when it is connected to a Amplifier like a car stereo then there's an Awkward ssssss or Hissing sound.
I've used Two Different models of the Redmi Note 3 thanks to Amazon and both of them have this.
It has a very very low possibility of hardware error.
When a song is played at 1/7 of the total volume, put your ear near the device speaker and listen carefully. You might notice a weird hissing sound. It goes away when there is deep and strong bass but is there lots of times.
Using an amplifier it is most noticeable at lower volumes.
I hope you people understand.
Respond ASAP!

Hey Guys.
I'm creating this thread since I did not find any other old thread about this issue.
When a song or any audio output is done through the Redmi Note 3's Speaker or when it is connected to a Amplifier like a car stereo then there's an Awkward ssssss or Hissing sound.
I've used Two Different models of the Redmi Note 3 thanks to Amazon and both of them have this.
It has a very very low possibility of hardware error.
When a song is played at 1/7 of the total volume, put your ear near the device speaker and listen carefully. You might notice a weird hissing sound. It goes away when there is deep and strong bass but is there lots of times.

I too faced that situation... But in my case..
The 3.5 mm jack is broken..
I mean.. There's no problem with the phone.. But in sound system I use...
Have you checked this problem with other speakers ...??

Hey,
I actually have noticed this when I played music in my Car and also from the phone's Speaker itself!
Both when the volume is Very Low....
I know it's not a problem with my piece because I've checked with many RN3 Users and same issue is being detected there too.
My RN3 is new and in superb Condition and so are the other Appliances like the Car Stereo I used.
Even then this Hiss sound is there.
I wonder of its a problem with the Chipset altogether since there isn't a sound/music chip in it...
I hope it's a software issue and gets resolved fast...
When recording sound from the speaker output yes the sound is levied towards the high end, this is probably what causes the hissing sound in your amplifier since it can't properly amplify that freq or something along those lines, I'm not too sure since I'm no sound engineer but that's just my 50 cent.
Edit
Dumb me, your amplifier is probably a 3.5mm headphone Jack right? If so then there shouldn't be this issue and my above statement wouldn't apply ;-;
I noticed this when using Viper Audio. There was a small but noticeable hissing in the left earphone. It went away when I turned off playback gain control.
Maybe check if any equalisers or headphone effects are on and turn them off?

I had checked everything possible. I even did now.
No part of the settings, equalizer, audio effects could fix it....
And where's the option you're talking about for playback gain control? I'm still unrooted with a locked bootloader on MIUI V7.2.3.0LHOMIDA
The sound is there in both speakers in my case. I'm not using anything other than the stock music application and some great songs on an amplifier I.e. Cars stereo
Anybody has got the solution? I am also facing same issue ??

Not till now.
I've bought this Bluetooth audio adaptor that serves my purpose in the car.
Funnily nobody at Mi noticed this.
I'll do a bug report highlighting this issue.
Everyone else plase do too!

I have also dropped them a mail. Will also report bug. Thank you for your solution but I'll probably have to wait as my car system does not support Bluetooth.

Even mine didn't support Bluetooth.
If your Stereo supports USB and Aux in, you can also go for the adapter since it only needs those two.
USB for Power and Aux In for the Music.

I had a similar problem. Whenever I connected my headphones to my Redmi Note 3, there would be a weird hissing noise at low volumes especially. At higher volumes, it would reduce. I found a fix to this on Reddit, but you need to be rooted.

Looks like a legacy. We are well into 2017 and the issue still exists. I bought my RN3 a couple of weeks ago and noticed the hissing on the third day of use. I just have been ignoring it. After all, it's a Chinese phone. I bought it and I have to live with it.
Good afternoon! The solution for problems with Redmi Note 3 and AUX is the following (solves the problem of correct detection and noise during playback): it is necessary to solder or otherwise connect resistors with a rating of 10 ohms between the common "0" wire and the left and right channel wires (I did 17 Ohm , did 10 ohms - both options work).
After you make this cable, the sequence of actions is as follows: the cable is first inserted into the smartphone, wait for the icon to appear with the headphones, and then insert into the AUX-input of the radio or audio system.
