Hi there!
I have been trying to fix this S4 (M919) which came without a T-Mobile rom (In Australia) and I have ran into audio problems over the past few days. I have attempted to fix it by recovering the modem but that did not help. I read about others fixing their phones with a simple flash but those i9505 firmwares do not work with this device. I flashed the T-Mobile firmware to see if it would work but still no sound (plus its not a T-Mobile SIM but that can be fixed by flashing CM12.1 )
It also says that in download mode it is a M919 but underneath the battery, it's a GT - I9505 (what?) I once fixed this problem a while back with flashing TWRP via odin and that apparently fixed it, for some time.
I have tried flashing: modem_CWM_UVUAMDL, M919UVUFOH3, GSM_Modem_XXUFNA5 (FAIL), Albe95_S6_PORT_V4-5 (Same problem as other roms 'no sound' and BL_I9505XXUHOA7_user_low_ship_MULTI_CERTXX
Roms I tried: CM 12.1, CM 11, Slimrom Lollipop unofficial, Albe95_S6_PORT_V4-5 and some t-mobile based rom.
NOTE: I do not use T-Mobile, however t-mobile packages work but I still have 0 sound from speakers & ear piece. ALSO, before this problem occurred, the name of the device when connected to the pc was GT-I9505 now after flashing 'M919UVUFOH3' it is now SGH-M919.
Right now it is on CM 12.1 nightly build (jfltexx) + open gapps + root and busybox (Still no sound)
Additional Information: I can send messages, download apps and everything but I cannot call nor listen to music (both speaker and earphones) Cm12.1 runs the best for now.
So can someone help me? Whenever I press volume controls, the phone would lockup (only on stock) and on other roms, there is also no sound (earpiece & speakers) also music players tend to crash (Such as AudioFX) . Please help me out!
You have a Frankenphone. In your case, it happens to be a US T-Mobile S4 that has had its IMEI replaced with one from an I9505. The ROM I believe is not the source of the issue here, but that the speaker module has failed, requiring replacement. The part should be on Amazon, and should be very easy to replace. Once you replace the module, install the Google Play Edition ROM from the development section and enjoy. Cyanogenmod should also work, but don't try installing a ROM ported directly from a Galaxy S6, like Albe95's ROM. M919 devices trying to run such a ROM will have no network and no WiFi, with no way to enable it.

Thanks for the reply, also here is the guy I bought it from. I believe your statement makes sense but if the speaker failed, why wouldn't the headphone jack work? I fixed it before with TWRP (weirdly) but here are some links. Is this module what you are referring to or is it the long connector that comes from the top to the bottom?

Speaker Module
You said about: "M919 devices trying to run such a ROM will have no network and no WiFi, with no way to enable it." I believe that is true as I tried that and I got no WIFI at all So you solved some of my worries
Well, now we know why he cannot post to the United States. He's knowingly selling these Frankenphones. The IMEI was likely changed because the original IMEI was blacklisted.
As to the speaker, I only went by the evidence presented. You had tried multiple ROMs, both Touchwiz and otherwise, and none of them resolved the speaker issue. Ergo, the only remaining possibility is that it's a hardware issue. Your fixing the issue in TWRP is odd. The fact you were only able to do it once and weren't able to do it again leads me to believe that TWRP "fixing" the problem was a placebo effect and that there's something else wrong. Now, I believe the speaker module to be the culprit, but do not remember if the audio controller is located on that module.
Where both speaker and headset are not working, you may have a mainboard issue, which will require you to get your money back from the guy you bought this S4 from. Then get yourself an untouched S4 using your XDA account and purchasing through Swappa. With Frankenphones, I ALWAYS recommend getting your money back ASAP, as they often are more trouble than they are worth.

Well, as I said I fixed it with TWRP and I believe (I just confirmed and remembered) I fixed the problem again (about 1 month ago) by flashing CyanogenMod this time. There are links that prove people have fixed their devices with various methods.
Also, if it were to be a hardware problem, why would the audiofx application crash, volume control menus hang on stock firmware and no ear piece sound? It just doesn't make sense! If you have any other solutions please tell me! I really want to fix it but I am starting to believe it is a hardware problem. I really hope it isn't. Also, I confirmed the IMEI number and its a i9505 but in odin mode, it says sgh-m919 :/
Cheers!
just out of curiosity, can you get sound through a pair of headphones???
just because I had a problem of having no sound before, and it turned out that the headphone socket was damaged , in such a way that the phone ALWAYS thought it had a pair of headphones connected, thus no sound from either of the internal speakers.
i had to replace the headphone socket on mine (real easy, it just clicks in place) and since then, no problems.

Nope. It isn't headphones or speakers because the software will also crash if I have problems like that. If the software worked fine (no hanging with volume controls or media players) then the speaker/3.5mm jack module would need replacing. I think I got a dodgy factory second handset. Will probably send it back for warranty to the seller.
PS: The S4 ain't mine. It is my sister's. Furthermore, it is an m919, no a i9505 (I checked via the IMEI numbers)
Well congrats on fixing your headphone jack!

(I think) there is no variant in galaxy s4 known as m919,so it might be i9505

@yahya wessam: SGH-M919 is a T-Mobile (US) Galaxy S4. He most definitely does NOT have an I9505.

Oh wait there is, i thought there is only 2 variants:
i9505 and i9500

Those are the international models, but there are also a dozen different models just for North America.
Yea. Faulty factory second phone. We will send it back and hopefully they will replace it.

Lately I've been having weird issues, each pair of headphones of mine mysteriously stopped working in the left ear. If I wiggled it around a bit, the sound would come in and out of the left headphone.
So I got fed up and decided to flash the original firmware to take it back to the store where I still had a warranty. Once I flashed it I decided to test it, and sure enough the headphones now work perfectly. I wiggled furiously and could not get the sound to go away in the left earbud.
But from my understanding I didn't know that a firmware would be able to screw that up? I thought for sure it was a hardware problem. Can someone else comment on this? Or tell me how this is possible?
Thank you guys!
Hi .. Certainly it isn't the fault of the firmware .. its just a coincidence that you flashed the stock firmware and the headphones started working
Its definitely a hardware issue afaik ...

Good day,
I just have bought an Motorola Bravo phone of the ebay and it has one strange issue.
When I call to someone they can't hear me, but if I turn on speaker, they hear me fine.
What could be the cause of the problem ? I have dissasembled the phone and saw that the microphone is not replacable ( it is soldered to the mainboard )
Can you guys help me ? Thanks.
Also the android version is 2.3.4 with non working camera (dunno the rom name)
Did you try a factory reset?
I would not bother flashing stock since doing that would give the seller grounds to deny your refund claim
Just contact the seller and return the phone. I think ebay covers all your purchases including shipping charges.
Too late, I just have flashed stock 2.2.1 rom with RSD Lite and the problem is still there.
But I do not get why there is totally no voice when I speak but when I turn on speaker everything is fine. Is it really hardware fault ?
/update
Tried factory reset, nothing.
Also after reflashing to stock rom I did notice that the kernel version is still the same. Maybe thats the cause of the fault ? before there was strange chinese rom in my bravo, I thouht it messed up microphone and stuff
If you flashed a stock 2.2.1 and it didn't fix it then I think it would have to be a hardware problem... unfortunately it sounds like someone tried to unload a messed up phone on you, hope you didn't pay to much for it.

But one thing I do not understand, clearly there is only one microphone in this phone, I have disassembled it, but one sure thing I can not understand, WHY MIC WORKS WHEN THE SPEAKER PHONE FUNCTION IS TURNED ON DURING THE CALL ? It works flawlessly, but if you turn in off, no sound at all at the other end.
What part of the phone software is responsible for hardware ? Is it Kernel ?
Thanks for answers guys.
I agree that its really weird... I honestly am not the best person to advise you on this particular subject I don't know much about the hardware on this phone besides specs... so if you don't get any good help on this forum (we have low dev activity) you could try a more general and active forum.

Did you solve your problem?
I have a similar problem, I can be heard good only when I speak over bluetooth.
Hey mate.
Finally I found out that Motorola Bravo has TWO microphones, one for calls, other is on the back near the camera and it is used for video recording/speaker during call.
So I think I have faulty microphone. But not 100% sure. Still dunno which part of software drives hardware, specifically microphones.
Anyways I receive no answers to this problem. So generally I think my front microphone does not work but the rear one works perfectly.
So maybe there is a way to change the usage of the microphone during the call ?
That the rear microphone would be used and not the front one.
Cause some recording apps let me do this like "TapeMachine Recorder"
Hi!
I had my S4 (I9505) serviced a few months ago. Warranty repair, they replaced the whole mainboard. The repair took forever, and when I got the phone back, I already had purchased another one (second hand) that I liked better (Xperia Z1 compact, I liked the size), so I tested the repaired phone was working, but no more than that. A few months later when I missed my big screen and some custom ROMs I took back my I9505 and started using it with stock ROM. I soon noticed people couldn't hear me when I was on speaker phone. Then I flashed a few aosp and CM based ROMs, and realized it wasn't a software issue: it did not work on those either. And when trying to dictate something, or use voice command, the phone just doesn't "hear" anything. So the same mic must be involved in those operations, which makes sense since it is when you speak from further away from your phone.
Unfortunately, months have passed since the repair and the phone is no longer under warranty.
I started investigating a little bit, and it seems there are two microphones on the phone. The regular one works well but the other one not at all. So, here are my questions:
1. Is the second microphone located on the top of the phone, next to the headphone jack? If anyone has a diagram or picture of the board with the second microphone marked, I'd be happy to see it
2. How is that second mic connected to the board? Is it a cable, a contact or is it welded? Or is it integrated on the board?
3. If it is a part that can be replaced, where can it be purchased?
4. Anyone has had the same issue? If so, could you solve it?
Thanks in advance!
Cheers!

Hello. A few days ago I lost the sound on the left channel on my N910F. I tried with different headphones (and also my headphones on other phone). The headphones are ok but I have no sound on the left channel (the headphones microphone works though). I tried cleaning the internal connector as good as I can but no luck, so I sent the phone to a samsung service for warranty. They called me the next day saying they wont touch the phone because it is rooted which voided the warranty.
Is the phones connector a separate module which I can change myself? If so how expensive is it? It also could be the motherboard... I only used dr ketan's rom and emotroid on this phone... I've been rooting and flashing samsung devices sice the S1 days (every iteration) and never heard of something like this.. that's why I'm blaming a physical issue with the connector.
Thanks.

It's the right channel which is not working, the left one is ok. I am now ordering the replacement part, if anyone interested here's how you change it: https://www.youtube.com/watch?v=QsUhVTj6Drc
I applied a DBT or German update to my N910F for marshmallow and then RRemix which resulted in the sound problem.
I cleaned the headphone jack meticulously
tried reinstalling the different ROMs and firmware available
Then I bought a replacement headphone jack and the repair man tried it, the original one again and even his own headphone jack, all 3 of which produced no sound
I placed it in safe mode and even attempted to boot it with the headphone
I have no idea what to do. The only clue is dm-verity fail after flashing the firmware. Maybe its the sound drivers or jack connectors being unclean?

Flash back stock firmware and see if it works otherwise it could be hardware fault.

Thank you for your assistance
I tried:
- Reinstalling multiple stock firmwares of different updates (up to Aug 2017)
- Different MODEM and Bootloader updates
- Restarted the device with the headphone jack plugged in
- Recleaned the headphone jack multiple times
- Tried three different headphone jacks, including one new bought from Samsung
- Installed different ROMs, including RaceROM and LineageOS
- Experienced 'Camera cannot be accessed error' and inability to use torch, which is solved by removing the battery while the phone is running
- NFC is also not working even on stock, suggesting a problem in the connection between battery and mainboard/components (power?)
Two different repairmen told me that the probable area of the defect is the mainboard, around the clips that connect them, maybe even changing screws for the ground?
For future reference - Managed to get to the bottom of the problem
A new audio ic on the mainboard was needed, Samsung stated they would have to replace the entire motherboard for the ridiculous price of 180 USD equiv, some engineer said he could solder a new one onto the mainboard, end of story
