I have a Samsung Galaxy S9+ with a strange issue..
After restarting it, all seems well.. Ring volume is fine when the phone is called.. In about less than an hour, the ring volume dies down to being so low that when it's in your pocket you can't hear it. Restart fixes it again for a few minutes.. I've done a lot of analysis and worked out that what happens is the bottom speaker simply goes silent. When it works fine, I can enter *#0*# and test the both, bottom and top speakers and all is well. When the ring tone goes almost silent, the same test reveals the bottom speaker is completely silent. The strange thing is that the bottom speaker works after restart for a variable amount of time. For instance, I had it on a flat surface and it called it every 10 minutes. After about 50 minutes it suddenly went silent. Also, after restart, if I play a music file it starts out fine and plays fine for half to one and a half song. i.e. it will after a while suddenly go mute and the only sound comes from the top speaker, which is of course a lot lower. I think this is not software related, because I've done a factory reset, which didn't change anything. I know that both the top and bottom speakers are drive by separate MAX98512 Audio Amplifier chips, so that seems to indicate the bottom speaker chip seems to cut out after some usage. The phone is out of warranty, so returning it to Samsung might be costly as they would simply quote for replacing the main board (That is where the amplifier is located.) I've gone into debug mode (*#0283#) and done a dump, which I then copied to an external SD card. I've tried to find any errors in the messages related to this i.e. max98512 hw and debug messages, but I'm not used to reading these. My remaining option is to rip it open and follow the diagnostic procedure to check if the MAX98512 chip is faulty or not. What bugs me is the fact that it works fine after restart and then suddenly dies! Anyone had any experience with an issue similar to this?
I have some issue .
did you solve the problem?

Hello, I am a new user here.
I have a strange problem with my Bolt where at times the rear speaker plays all streams (alarm, notification, ringtone, media, etc.) so quietly that I have to put my ear directly next to the speaker to hear anything. At random times the speaker decides to play at normal volume again. I do not really hear a crackling sound so it seems the speaker is not blown.
The issue occurred when I was using SynergyROM for Thunderbolt r264, but the issue still occurs when I do a nandroid restore to a ROM I flashed previously when the problem did not occur. I am now using CyanogenMod 7.1.1 for Thunderbolt and yes, I am rooted.
The headphone jack works fine, so I'm guessing it has nothing to do with the system volume control. However, the problem sometimes occurs as soon as I plug in my headphones and then unplug them.
Does anyone know what I can do besides taking my phone to Verizon (my carrier) or a phone repair shop to fix this?
I have this same problem. I would also like to know what the cause is. It is very annoying because most of the time, I cannot hear my phone ring.
I think this may have something to do with the system thinking that headphones are still plugged in. I am running a Theoryrom based off of CM7 and if I go into the CyanogenMod settings in the sound menu and check the boxes for notifications, ring tones, and alarms to always play on speaker, all of a sudden the speaker volume seems to have improved. Something you may try. If it happens again on mine (which it will) I will see if I can figure out what the problem is.
Nevermind, it went back to being quiet, and that doesn't seem to fix it. Must have been a fluke.
It seems like there is no indication of when it will happen. Is it a hardware issue or an issue with the Android system and plugging in a headset?
My initial guess would be that it is a hardware issue. I have tried flashing new and different ROMs ranging from Sense base DasBAMF roms to AOSP based liquid roms and the problem persists even after a flash, which to me would indicate that it is not an issue with the Android system.
The last time it came and went for me had nothing to do with plugging or unplgging a headset. I have no idea what is going on.
Ok, so my speaker came back this morning, and I did notice one potentially related thing when it happened. Just before it came back, the DSPManager application force closed. I wonder if something is wonky with that program. If you are still having issues, could you try to force close, uninstall, or freeze (using Titanium) the DSPManager application to see if your speaker volume comes back?
Update: Nope, not it. Must be hardware.
The strange part about this problem is that nothing wrong seems to be happening with the software when the sound comes back on. Also, I have to play music constantly in order for the sound to come back on. It doesn't seem like the speaker is blown out... there is no crackling sound. The sound is just really really quiet.
Alright, I finally decided to replace the speaker unit inside my phone because it would no longer go back to the original volume. It seems my hunch was right. The new speaker is working perfectly now.
The last couple weeks my phone has started to do this weird thing it has never done before. I plug my Vibrant into my car's head unit using a 1/8 inch to 1/8 inch audio patch cable. Whenever I remove the plug from the phone, the slider for "Media Volume" is overlayed on the screen and quickly drops to '0'. I have to pull up my mixer every time I get in the car and bring the slider back up to '15'.
I've had similar issues with the phone in the past, where plugging in will automatically start the music app, but there are several headset blocker apps that work fine and prevent that. These apps have no impact on the present issue, though. Anyone have any idea how to stop this?
I've seen a lot of mention of a "mute bug" in various roms. A search for that, or maybe "unmute bug", should provide some info.

Right, so this is getting pretty frustrating now...
Basically my external speaker isn't working, however every now and then it works fine....but only for a little while, and then it cracks it again, and it's back to silence, and the inevitable missed calls, missed alarms etc....
The headset works fine (and i'm pretty sure it disconnects when i take it out, as i'm running an audio mod that has a notification icon that disappears when i remove the headphones), the mic works fine, people can hear me fine on calls, i can hear them fine. The phone is NOT on silent mode.
I am running cm9.1....i have replaced the usb flex cable, and just replaced the external speaker. When i replaced the speaker, it seemed to fix the problem...i had a day or two of perfect sound, i was hearing notifications, calls, everything....then, back to silence.
Whenever i go to turn the volume up (in the vain hope of this working i guess), there is a short "click" sound, then nothing....if i press the volume button again, no click.... and as i said at the top of the post, sometimes it works just fine.....daaaaaaaaaaah (frustration noise)
Any advice, tips or magical fixes would be appreciated....

Click to expand...
Click to collapse
...replaced the audio jack assembly. fixed the problem for two days, now it's back to silence.....i'm about to throw this phone against the wall!
I got a new screen (glass, digitizer and lcd) so
After everything has been put in place, I tried the phone and everything seemed to work. Vibration, connection, sound, and touch screen. So I made everything close and I first set on my phone.
I was called but people do not hear me. Tried again, but people still do not hear me. When I got on whatsapp a voice message recorded but that just working so the mic is working fine. on speaker they can hear me to.
I double checked the cables but everything looks good. I also did a factory reset but no one can hear me..
Anyone know whats my problem?
I can replace the whole cable system witch is atached to the mic but i dont know if that is the problem because the mic work…
Find something interesting:
In the service menu i can test the first and second microphones. The first one record nothing and the second one records as normal.
The second one i find out it is the mic at the top of the phone.
So the first mic must be the one at the bottom.. Dead i think?…
There are 3 ways this could've happened:
1. Just a software glitch. Unlikely, but it's worth doing a factory reset.
2. Mic broke when they changed the screen.
3. They forgot to connect the mic that's not working (if it's a connection and it's not directly on the m/b)
Option 2 and 3 require reopening the phone.
When I place or receive a regular call the other person can barely hear me unless I speak less than 0.5 inches from the microphone. At less than 0.5t inches, they hear me good. At 2 inches extremely muffled or nill (this is the distance of the mouth in a regular call), and at 3 or more inches nothing at all.
Physically the mic however works fine when recording videos, so it has to be something non-physical. Also confirmed with a test on the Microphone at *#*#7378423#*#* where the both primary and secondary mics record fine.
In desperation I used flashtool and re-image the whole thing (even with erasing all data) with the latest XpriFirm ROM and tested it right after the successful image and without installing any 3rd party apps. The problem still there.
I also tried 3 different ROMs from different countries, but the problem still there.
Using a external wired headset mic works fine.
It seems, like a setting that is aggressively reducing the mic sensitivity just for the phone calls.
Ruled out 3rd party applications, mic physical damage or normal Android setting, I am really lost on to proceed from here!
Does anyone know what to do?

Model: E5823.
Bootloader has never been unlocked so no root.
Do you have the volume all the way up during the call? As in once call is started turn it up.
Idk how much it will help but have you tried to flash the soundmod? I have never had a problem with the mic other than a small echo on speakerphone. Also have you tried speakerphone wile in call? Might be something wrong with the phone apk, try a third party phone dialer? It wouldn't hurt to go through the sound menus to check everything as well.
Hi!
I doubt is a setting (in the Sound Effects options everything is off) since I flashed a stock clean ROM.
Did not know there are alternative dialers... I will study them today.
Regarding flashing the soundmod, can you do that without being rooted? If so, i'll search in how to do it too.
Cheers and thanks from just a couple of dozen miles south of you Sagnasty.
Have you tried to change the value of microphone sensitivity, although the option is in the Settings / Sound and Notification / Accessory Settings - turn mic sensitivity to high and see how it is then in a conversation?
The Speakerphone as suggested by civicsr2cool was surprising... the mic just picks up voice just fine from the distance in that setting!!
Then I just played with those mic sound settings as per Monipeev, (I did that days ago) but now it did something and in any sensitivity setting works fine... it must have been playing with this setting and the speakerphone one that may have unstuck some mic glitch.
Thanks so much guys... and two think I spend hours trying to solve this and even flashing ROMs! :victory:
Hi everybody. It happend to me with my Xperia Z5 compact as well - the mic did not work properly during call, but when I tested it offline the mic was OK. Playing with settings did not work as well as factory reset, so I ordered microphone spare part from China (ca 2$) and replaced it. Then the problem disappeared. I agree with polar_bay above it seems like mic glitch - I think my spare mic was slightly different from the original (maybe less sensitive) and that's it. Maybe also complete voltage drop (battery disconnection) helped to unstuck it.
My recommendations are:
1. play with mic settings (sw)
2. open the phone and disconnect the battery for a while (1 minute)
3. place small&thin absorber between mic and hole in phone case
4. replace microphone
hi, I have just bought another used xperia z5 compact as my other device has gotten old. after I received the new one I almost directly rooted it installed twrp and flashed lineageos 17. after a while I recognized that the microphone is not working during calls, only if the speaker is enabled. also when i want to record audio or use the tuner it doesn't work.
is there any chance to find out if it is a hardware problem or if it can be solved by some setting or so, be it coding?
thanks for any hints!
