[Q] No sound from speaker + mic not working - Galaxy S II Q&A, Help & Troubleshooting

I have had this problem for a while now.
I don't have any sound from my loud speaker in my S2, and the microphone is not working either.
I can only hear sound/use a mic when I connect an earphone (mic working is the earphones' mic).
I replaced these parts with new ones:
- earpiece speaker flex cable ribbon
- Loud Speaker Ringer Buzzer
- USB dock port flex cable (since the mic is in this part)
Nothing changed.
I'm pretty certain it is not software-related issue since I installed many roms since, and I even got back to stock, but it won't change anything.
What do you guys think? Any way I can resolve this issue?

You are not gonna like my response but its time to visit service center or mobile repair shop.

Thanks ☺
It's probably the motherboard right? Don't see much value in reparing it if this is the case since phones are getting pretty cheap today...

[Q] Problems with audio jack

Hi all,
to my great frustration, I've discovered that my SGS2 line-out / headphones jack seems to have a slack joint, i.e. if you turn a connected plug around its long axis, a crackling sound is heared in the speakers and at some angular positions the stereo signal will be reduced to mono (i.e. one speaker gos silent). With one device (mobile outdoor speaker) I even had no sound at all at when inserting the plug with the wrong "orientation".
Did anybody experience the same problem or am I just out of luck here?
I am wondering whether sending back the device to the retailer (Amazon) or directly to Samsung (I'm situated in Germany) will yield the faster round-trip time, any experiences here?
Thanks!
PS: I know this may be a stupid question but can somebody PLEASE tell me how to search for multiple keywords with AND logic in this forum? Tried "+word +word" and "word AND word" (without the quotes) but nothing seems to work.
Are you using the headphones that came with it? My better half went through 4 sets of the stock samsung headphones with her original Galaxy S and all produced the same issue of losing one channel after a matter of days/weeks. having the jack inserted to about 2/3rds is a workaround but not ideal as you still lose some frequencies and it's insecure... They're just a bit pony.
No, I used different kind of headphones, including Sennheiser in-ear headphones and a standard male-male audio jack connected to some bigger hifi system. With some jacks I did not encounter the problem, but most of them lost some part of the signal with some orientations: I persume that the manufacturing tolerance of the jacks also plays a role...
Anyway, it's definitely not a problem of the jacks but of the device since I tried it with the SGS2 of a friend yesterday and it worked with the same jack that made problems with my device.
I will proceed sending my phone to Samsung for repair, I hope that won't take to long *sad looking*, I am so used to it now, it's card to survive to weeks without it.
I had the same problem, all I had to do was insert headphones cable "HARDER" into the audio jack until I herd a "click" sound.
I was way to over protective of this phone when i first had it, and wanted to handle too much with care, forced the dam cable in, and "click", sounded like it snapped into place, the audio worked correctly without cracking noise or without the need to wiggle to cable get clearer sound.
Perhaps your friends SGS2 is already used to headphone being inserted, but yours not. Just add a little pressure until you hear clip into place.
If this doesnt help, then repair or return.
Thanks for the hint, but unfortunately I had the jack inserted to the very end, so this was not the problem... sent in for repair now, let's see what happens.
I have a fix for you i think!!!!!!!!
ok . when i got my s2 like 4 days ago (at&t usa version) i noticed that when i plugged into my aux cable in my car that it was low sound cracking more volume on the left side , very annoying . NOW FOR A SIMPLE FIX FOR SOME TO TRY! PLUG IT IN ALL THE WAY! i noticed when plugging it in i wasnt fully plugging it in . it should go all the way down FULLY! the sound is perfect once this is done . I HOPE THIS HELPS YOU !!!!!! good luck

SGS2 Audio Problem

I've got my phone for around 2 months and last Friday dunno why I can hear the audio (music in-call or any type of sound) in only my right headphone, the left is silent and even in the right one I can barely hear anything... Does anyone know if this is related to KI8 or is my audio jack just f****d? (I tried like 6 headphones all the same problem and on my g-tab 10.1 they work fine)
Audio jack pushed hoe audio settings one channel turned down .
jje
Is there any way to fix it without sending it to a gsm center or a shop?is
Hey. Just wanted to let you know in my truck with aux cable it does the same thing. All sound is higher in front right than any other speakers. Someone help!

[Q] Marshall Minor incompatibality

I racently bought a Marshall Minor earphones but it doesn't fully work with my xperia neo. I cant use the mic. Is there any way to fix it
The earphones themselves should work just fine, just not the mic and that's because for a phone a mic isn't just a mic, it has to have the software and settings necessary to control that mic but phones only have the settings for their mics to work. It's not that same as a computer where you can just stick in any old mic and and it will work. A phone has to know that your earphones actually have a mic and since it doesn't know these earphones it doesn't know there's a mic there and you can't tell it there is one.
Short version: You're screwed, the phone will never recognize that mic.

[Q] Phone mic or in line headphone mic issues

I'm getting a strange problem on my note. I have a pair of inline mic headphones.
While the headphones with the mic are plugged in the phone's mic is turned off which is normal...but the mic isn't working on the headphones. Before you say its the headphones I tested the headphones with a call and voice recording on my sisters galaxy s and my old moto cliq.
Another strange problem. the phone mic also turns off when the apple non mic headphones are plugged in.
Are my inline mic headphones not working because of a hardware issue or software? I'm on hybrid with the any dpi tablet mod on stock dpi.
I'm not going to return this note because It's my third one. After two defective camera units.I'm not going to risk getting a more defective unit.
My current note is however having the known problem bottom right corner.
Any insight on my headphones issue?
It doesn't make sense for them to work on the outdated galaxy s and moto cliq but not my note...

[Q] Only left earbud works, jack problem

Hello,
Here is my problem: Suddenly for no reason at all, the R earbud stopped working. My thought was: "Oh well, it happens with earphones", after that i bought some earphones without microphone which had much more clearer sound, and both of earbuds (R&L) worked well, untill few days ago, suddenly the right one (R), drop dead. I thought that it was again earphone problem, but I've tried to put them to my laptop, stereo, etc. and they worked just fine. So, I thought:"It must be audio jack problem". And it was, because now only left one works, and I must twist earphone plug in a strange way for both of earbuds to work but it is impossible to me to hold them all the time like that.
My brother has also galaxy S3, so I borrowed his original Samsung earphones and I didn't have to twist them or bend them. They just worked fine, both of earbuds. So I've done some searching over the internet and I've learned that it could be some contact problem in jack, that one contact is loose. My question is, how to fix that fast and cheap, because I'm cheap and lazy bastard. I would like to know if there is any solution to my problem so i won't have to go to Samsung service. I've seen that there are replacement parts for audio jack + speaker on eBay, any experiences with that?
Best regards!
