[Q] External speaker problem...motherboard issue? - Galaxy S II Q&A, Help & Troubleshooting

Has anyone had issues with the external speaker on the i9100?...
Mine will sometimes work for a few seconds then cut out...sometimes it won't even do that, just emitting a "click", like when you unplug a connection...ringtones never work (ever)...(and no, it's not on "silent")
The headphone jack works fine (and has been replaced already), and I've tried the "plug in plug out" solution. The call speaker (against the ear when on a call) works fine, and the Mic works fine....
I'm running cm10 and the latest siyah kernel, but this was happening when I was on stock and not rooted....
I replaced the speaker, and it worked perfectly for a day or so, then....not so much
Everything else is smooth as, and it's a great phone....would just be nice to be able to hear it ring is all...

did you recheck your speaker? maybe there was a loose wire or something.. there is a possibility that it may be a motherboard problem but i highly doubt it

Replace the USB flex cable board. I had the same exact problem. It instantly fix it but swapping that board my bring signal problems. Then refer to this thread.

all good now! i replaced the usb flex. when comparing the two boards, the new one has a slight curve in it that seems to bring the contacts closer to the speaker ...don't know if it's by design, but it works....my phone rang for the first time in ages this morning, and it scared the crap out of me

Head phone is not working!!!

Tonight I try to listen some music on my Tg01 and I discovered the head phone is not working, the answer button on the lead is not functioning either. I dont think is the lead because I keep it very safely and very careful not to damage it, I suspect is the micro usb jack is faulty but I can sync with PC with no problem. Have any one have this problem before?
If I can`t solve it I just return it to Orange for a new phone Phone just 6 months old. Hate to buy a new lead because I just can`t find it and I don`t think that`s the problem, not to mention waste of money.
I am using FFboy WM 6.5.5 Sense 2.5 Beta3 rom BTW.
Problem solved by new micro usb headphone lead. Toshiba one is broken ........

Where did you buy it from?
I got it from local market for £5, I am looking in to LG micro usb headphone adaptor too, I think it might work as well.

i think there's a nokia phone that uses the same adaptor too....

i know you fixed this...
but in case it helps anyone, my headphone somethimes doesn't work - the sound goes to the external speaker instead, but if i quickly dial a call (any #) & then hang up (before it rings at the other end) then the sound is diverted back to the headphones
Hi adzman808, I thing that this question was brilliantly explained in Modaco's forum by Kevin, some months ago....
http://www.modaco.com/content/toshiba-tg01-tg01-modaco-com/298887/headphone-amplified-sound-output/
I modified a couple of speakers (following the Kevin's instructions) with success. I had exactly the same issue, speakers worked perfectly but, sometimes, sound source changed randomly to device's speaker.
I just soldered a couple of resistors between left /right line and ground, as Kevin said, and problem has been definitively solved.
I'm sure that you have he same problem. By the way, in Modaco I was(am) Xdalover. Nice to hear from you in Xda dev as well.
Hope this help you
Cheers

I think it`s the same problem as my faulty toshiba lead, just yours is on the way out. Get a new lead and try it.

I believe this is a uUSB control software (driver) issue - have also experienced on occasion.
Typical scenario is when the TG01 has been on charge via the uUSB; unplug the charger and then plug in the external audio connector (eg. one of my home-brew cables used to feed an external 5.1 sound setup - see the Modaco post Pere has just flagged) - device refuses to put audioout to the uUSB and will only play via the speaker.
I have previously resorted to a S/R which evidently reset the uUSB controller to respond correctly to insertion of a B plug wired for audio.
Adzman808's solution is evidently achieveing the same result but by forcing a change of function call by initiating the phone call - hadn't thought of that trick !
I'm still looking unsuccessfully for source of the relevant chip that I identified in the previous post about the uUSB which is supposed to be able to support external charging and audio out and some other functions at the same time....

Internal Audio not working (hardware)

Hey guys, I have a hardware issue but first the background story
So my phone fell on concrete and the screen broke. I bought a digitizer and replaced it myself. After a month or so, I broke it again. I replaced it, but the unit I got was faulty, and I only got the replacement today.
I opened the phone again and replaced the digitizer, and it's working great!
however in the process I must have done something wrong since my audio/sound doesn't work anymore.
1)Loud speaker works just fine and the microphone works since I am able to talk to people and they hear me
2) When I plug in my earset, the sound works just fine on the earphone. The microphone switches over the earset's microphone and I can hear/talk just fine.
The only problem that I have is I can't hear anything if i put phone next to my ear :/ I opened again looked around, but didn't find anything obvious that might explain wha went wrong. Would anyone know where to look/what to test?
Cheers
anyone any idea please? D:
I haven't opened up my Mozart just yet but from my experience with HTC phones I would suggest checking the contacts of the speaker. They tend to have little springs on the speaker that come in contact with the mainboard and this is how the signal is transmitted. If these contacts are damaged then you will not hear anything.
With all the drops you may have damaged the speaker itself but I'm not sure of a way you could test that.
The problem i had was that I used my sony ericsson X8 headset and the sound came out funny, the thing that was cuasing it was the microphone. Try stock headset to see if it works. If it doesnt then you might want to get someone to check it or fix it. Up to you.

[Q] Earpiece and headset issue

I'm having some problems:
- The earpiece does not work in calls.
- When i plug a headset (one with mic and another without it), if volume is at max i hear just crackling sounds (nothing else) and when volume lower than max there's no sound at all.
i replaced the earpiece yesterday (the flex with everything else) and still have the same problem... so i tought it must be a software issue, then unlocked the bootloader and flashed cm7.2 stable (i was on at&t 2.3.6), but still, the same problem...
any help?
Sounds like your jack might be faulty.

the jack has something to do with the earpiece?

Oh sorry, I misunderstood. I thought you mean earbuds or similar. In that case, please ignore, sadly I have no other advice.

Same issue here - out of the blue my earpiece quit working. Did some research and found several posts that the earpiece was a possible faulty design by Moto. Like you I replaced the earpiece and flex cable. Earpiece started working fine, then it quit again. Then found something strange - when I removed the SD card it started working again. So to test, I put the SD card back in and it quit working again. Removed it again, rebooted and it was working again. Did this about 5 times with same results. Wake up the next morning, go to make a call and the earpiece is dead again. Its been dead since.
Was running CM 7.2.1 stable when this started. Flashed the nightly afterwards to see if that fixed it; nope. I believe its a software thing also so I'm trying to figure out which ROM I load next to test.
You guys have any luck?

Mine stopped working last week. After trying a few different headphones and doing all sorts of changes. I finally realized that I had a bit of pocket lining stuck on the instead which got embedded at the bottom. I used a paper clip to scope the lining out.
Any breakthroughs? Has any1 fixed the ear piece issue?
Please know if you do this ypu risk damaging your phone and this will be your decision.
With that said... If you remove the back panel you will find that the jack uses spring contacts to connect to the board. Make sure they are clean and making good contact.

Amaze 4G mic problem

My Amaze 4G for T-Mobile was rooted with s-on and flashed with Revolution HD 4.0 about half year ago. I had to change the digitizer/LCD assembly because it went dark. That went rather smoothly. However, the mic stopped working after that. I can hear people but they can't hear me. I did re-flash with the same ROM after the repair since the phone was having some other issues I thought might be software related. Didn't test the mic before the flash though.
The symptoms and what I've done so far:
-- People can't hear me during call. Turning on speaker doesn't help. Using a headset with built-in mic works.
-- The voice recorder app can't record a thing. Tapping the phone doesn't record either, so it's not dirt blocking the hole. AndroSensor app shows no sound input.
-- I can record video WITH sound. This was actually done after I replaced the mic PCB. Does this mean the mic is OK or the phone has another mic?
-- Re-flashed and tried another ROM, same thing.
-- Flashed back to stock T-Mobile ICS ROM, no good.
-- Installed SoundAbout app, played around with it, i.e., the headset plug trick, still no dice.
Since I can record video with sound, I feel it's more like a software problem, unless there's a secondary mic used for video recording but not phone calls. The sound doesn't seem to be recorded through the mic hole at the bottom as blocking it with my finger doesn't reduce the volume. I'm thinking to try the stock Gingerbread ROM as a last resort.
Any input will be greatly appreciated.

Since the Amaze records video in stereo, I have to assume there are at least 2 mics.

Make sense. It was working fine before I changed the digitizer/LCD. Thought I might broke something during the process. Checked the cables and they looked OK, so I replaced the microphone PCB but that didn't help. Could be a bad PCB though. May try to ask seller for a replacement. Does the problem sound like a software issue to anyone? I went ahead re-flashed the stock GB ROM but failed. I read somewhere the phone needs to be S-Off to do that. Any suggestions what else I can try to fix it?

Not a notion. It would be nice if there was some sort of schematic or youtube how-to for the mic. As for getting to S-Off, there is guide if necessary--do a search.

Replacing the mic PCB was easy, figured it out by myself. Can't be sure if I broke something else during the repair. I did search for S-Off guides and it seems the wire trick under Linux is the only way to go now. Since putting back the stock ICS ROM didn't help, I don't think the stock GB ROM will do any good either. The phone had ICS when I rooted it. Requested a replacement of the mic PCB I bought, let's see how that goes.

GS3 earpiece and headphone jack no longer working?

All of a sudden during a phone call the voice in the earpiece became demonic so I think I did a hard reset, since, no sound. Until it started working again. I had tried another fresh module I had in an electrostatic bag, but the headphone audio didn't work, so I put the original back in. Fast forward a day or two, now the headphone audio works in neither, and the earpiece doesn't work again. I'm wondering if this has any connection with the fact that I'm running unofficial CM12 with archi kernel and is not a hardware problem. The headphones are detected by both and the speaker works for both. What gives? :crying:
