Try reflash? or (shameless plug) try my EC07
It's def not the SD card, I have a class TWO which doesn't skip. Are you using Music Player or Google Music?

Sounds like a memory issue. At least for turnimg the display back on. Does it sound like a respawn?

Mine has been doing this too. I don't even have to push any buttons sometimes. It's happened when all I do is move my phone. I know it's not my headphones 'cause it's done it without anything plugged in. I've tried the clean ROM and Nuckin's ROM

It seems to do that too when I touch the grip sensor......

Do you have the sensor on? I don't but it still does it

I'm not sure if this is related, but I've noticed sounds in general are messed up.....like when I plug the phone into a charger...the confirmation beep is almost never smooth and clean....there is static or distortion in the sound effect......my ringer too....really all the sound out of the speaker that I've listened to. It is minor but still annoying. I haven't used the MP3 playing function on this phone since reflashing recently.
but my sound issue has been around on all the EC07 flashes I've done

My sound for plugging in USB has been laggy since imnuts hacked kernel. But that has been the only buggy sound
Sent from my SCH-I400 using xda premium

I think I misunderstood what was meant by 'skipping'. My phone does something where it sounds almost like there is a short in the connection for a second. And before i switched to t1231's reclean, there were times where I'd have to reboot my phone to get my headphone jack to work at all.
Here is my question. And the point where i probably sound like an idiot. Could this have something to do with voodoo? I know the recovery kernel is no voodoo, but I wonder if there is some correlation. I really don't know enough about voodoo to call this anything more than an idea I'm throwing out to see if it sticks, but if anyone more knowledgeable than me wants to chime in on it...

okay its deffintly the grip sensor i just went back to imnuts stock ec03 rom and it does it when ever i touch the phone my question is, is there any way to completly disable it because i use my phone for music more than anything.
actually scratch that im an idiot lol you can turn of active grip sensor in the settings and now it dosnt do it near as bad.

I actually don't think it was the ROM that did it. I think it was the new hacked kernel imnuts put up. Before that kernel my phone never did this. And it skips even though my grip sensor is off

You know that kernal might be it none of this happened before but it shouldn't matter now after I went back to ec03

Even though I don't think all those who replied in this thread were describing or even experiencing the same sound issues, I have solved, it would seem, the problem I was having with some sounds sounding distorted, like when plugging my phone in to my computer.
I wiped the cache partition and dalvik cache trying to solve a different issue, and now my sounds are all clean and pure as they once were.

now its all sound videos will just freeze and stutter sometimes when i touch the sensor

okay so i was just curious i decided to go back to completly stock dl17 and unroot after everything got booted i tested the music and it dosnt freeze at all anymore only slightly skips when you turn the screen off but the grip sensor dosnt mess up at all. so tommorrow im going to reroot go back straight to ec07 and see what happens i know for a fact it didnt skip when i first tried ec03.

4.2.2 update made my volume much lower?

I just got the 4.2.2 update last night and I immediately noticed the volume when I am talking on the phone is much lower. It honestly sounded like I had it on 50%, but when I checked it was still at full. Is anyone else experiencing this? I can only confirm this issue on the earpiece volume when making a call, but its VERY annoying.

+1, the volume during calls is lower

Curious, do you guys hear a buzzing static noise from the phone while NOT on a call? Screen on or off, shouldn't matter.

Reflash the whole 4.2.2 factory image in fastboot mode. Downloadlink https://docs.google.com/file/d/0B_zuNWpIf1ujTzFkUkF5OWdkUmc/edit?usp=sharing. That should fix your problems. Backup your files first as it will wipe the sdcard.

Is that a known method to fix the low volume, or is 4.2.2 just "tweaked" poorly by Google?

I am not rooted so I can't make a Nandroid backup. That means I will lose all my data which would be bothersome.

Nandroid doesn't back-up your ext sd.

Thats a good point! However, before going through the whole wiping process I am hoping someone else can confirm if that method will actually fix the problem.

I flashed 4.2.2 that way. Not had any problems with sound.
Now i'm on PA rom. Also no problems at all

AW: 4.2.2 update made my volume much lower?
Hi, I also have a big issue regarding the sound respectively the equalizer. Its important for me to have the possability to change bass settings while listening to Internet radio. The app I usually use is yourmuze. The stock equalizer only works with Google play music, but not with yourmuze. I contacted the yourmuze-support, but they had no clue... I also tried different radio-players, but it seems, that other apps than Google play music are not supported. I tried CM 10.1, but same issue there. I also installed another kernel. I'm currently on stock (rooted) with awesame beats, which works only with Google play music. What the hell is blocking the sound options? It really sucks and I'll sell my N4, if I can't solve this problem soon. I use my phone as a musicplayer min. 1 hour per day. Could it be a hardware problem? I don't think so, because awesame beats works perfect with Google play music. Maybe one of you guys can help me?

Unfortunately I tried the solution listed here and that did not change the low in call volume I am experiencing since doing the OTA to 4.2.2. Does anyone else have other suggestions? It appears as if the volume "boosting" apps on the market are not compatible with JB. Am I out of luck here???

I too am unrooted and upgraded to 4.2.2 and have noticed the same thing as you OP. It is bad on speaker phone as well. To those that flashed the factory image via bootloader as a fix is it more because of the issues around OTA or because you suspect a bad flash? In other words, if I am going to go through the trouble of backing everything up and wiping, I may as well root and flash a custom rom/recovery. Any thoughts?

I applied the 4.2.2 update earlier and also experienced a noticeable drop in call volume. In fact, it’s been so bad that I can barely hear anything at all when I’m somewhere noisy, like a coffee shop.

Agreed, I have a hard time talking on the phone if I am on the street now since I simply can't hear the other person.....

BUMP, hoping we can get some attention to this issue.

Same here
+1 Volume is so low that I'm having trouble talking on the phone. Both regular and speakerphone affected.

Try this experiment. When in a call slide the volume to both extremes and then adjust to what you want.
After my update I couldn't raise volume, it was like it was uncalibrated. So I had it at 75% and when I went "up" the volume didn't change. By going all the way to minimum and back to maximum seemed to "calibrate" my adjustment and I can raise and lower call volume reliably now.

No sound.. Even at the highest volume.

It not a speaker problem defiantly...
Any suggestions???

My Dad had a similar problem on his iPhone 2G once and it was to do with the headphone jack. Try plugging something into the headphone jack then playing some music before taking the headphones out then playing again. I know it seems weird but it worked for my Dad and it won't take long so it's worth a try. It's not very likely to work though because his iPhone was a solid 3 years old at the time and very beaten up, you probably haven't done similar damage to your phone in such a relatively short time period.

thanks for your suggestion...
tired but to no avail... i noticed this is most likely a software issue... as after a reboot ..sounds works perfectly for a period of time (30 sec.... 10 mins) then after that ... sounds goes off (playing about... going to settings etc...)... and the only possibility to fix this is to reboot..
this happens on stock 4.2, 4.2.2, Cm10.1 RC1, Xylon, etc..
can't seems to pinpoint the fault...it seems to go to mute... but the volume rocker still shows volume is on... and move it up and down does not solves it..
when plug a headphone into the unit, is it supposed to show a head phone is plugged in ?? i don't seems to get that..

I would reflash a factory image in fastboot, if that doesn`t solve the issue it may be a hardware issue that requires repair (relock the bootloader in that case).
BTW do you have sound with music, youtube etc?

I had a similar problem when i flashed the Sony sound pack ported from xperia z. Every single sound vanished from the device, even speaker and mic when making a call! Restored a backup and it has since worked fine!

If you can, flash back to stock and RMA it. This isn't a common or normal issue and you probably won't be able to fix it yourself that easily.

No Sound - AT&T Samsung Galaxy S4

Tried searching the threads but didn't find anyone with the same problem. But for some reason sound stopped coming out of my phone. When I say sound, I mean if I try to play any music, use speakerphone, videos, alarms, keypad tones, etc. No sound will come out of my phone. I can make a call using the phone but when I try to use speakerphone nothing comes out. I can hear someone when I'm talking to them on the phone and they can hear me fine and earphones also work fine.
I tried Odin back to stock, then doing a factory reset and even with the factory reset I still don't hear anything when the AT&T logo plays when the phone is turned on.
Any ideas or suggestions? It was working fine this afternoon then for some reason all of a sudden stopped. I'm not sure if I placed my phone in my glove compartment too hard or if I did something else that maybe dislodged an internal cable or something.
Any help would be appreciated.

Looks like you may have a physical problem with the phone. The main speaker is dead somehow. That speaker does music, alert noises, etc, while a separate speaker does your in call audio (directly to your ear so the call is private..). This happened to me once on my iPhone4 where a tiny tiny tiny tab of glass cleaner got into the headset when I was cleaning it. it dried and sorted itself out within a day. If that's the case with yours try drying it out. If not, then you may have to submit it to Samsung or your carrier for warranty.

Thanks for the reply, WoodburyMan. I'm thinking my phone might be experiencing a "supernatural" problem. For one reason or another my alarm went off this morning and everything started to work fine. Although there were some syncing issues with my Gmail. Who knows, last night when all this happened, my battery was at 50%. Maybe it needed a charge or just a night to "sleep off" its issues. In any case, it seems to be working fine for the time being. Hopefully it stays that way.

i was having a similar problem and don't know what is going on. All my sounds work and for some reason when i silence my phone and try and turn the sound back on EVERY sound works EXCEPT for my Media. like notifications, bleeps , etc all work but i can't hear music at all and i can't unmute it. ive tried a whole bunch of stuff and did a reset and nothing yet. As soon as i restart the phone, then the media sound wrks again.. any ideas?

Ear speaker not Working in Galaxy S4.SOLUTION FINALLY FOUND
I hadthis problem for a lot of time...when i was on the phone with a call instantly the sound was off...the loud speaker and the headphones and bluetooth were ok but the ear speaker was off. Firstly i thought that the cause of the problem was the fact the i have rooted my phone...i change a lot of roms... and some times the ear speaker was starting to work but then the same think instantly went down...i unrooted my phone but the problem was still there.... I TRY also the function *#0*# and when i push the botton of the "reciever" some times was working some times not..... when i was playing on this one time i push hard on the screen and has start to work again,.... Then i thought that the time to open the device has come.... Some youtube help on how to disassebly a galaxy s4 and i found the connector for the ear speaker...... i cleaned it... i used the hair dryer and the a connector spray for mantainence and the problem was fixed....I have seen after 2 days reaserch on the net that many people with a galaxy s4 have this problem.... in my opinion is a matter of humidity in this connector.... after hairdrying and a connector spray my phone was fixed... No need to send it back to samsung ....and pay money..because its rooted..(my knox counter is still 0x1 ) .
That was all falks .. hope to help somebody... its very easy to fix this problem once you understand the cause of it!!!

Sort of the same problem with s4 i337m
I recently flashed CyanogenMod on my S4 and now I have no volume at all. Anywhere. I also can't play videos of any kind. Snapchat, youtube, or web videos. I also get no volume with ringer and in call. I have tried flashing different ROM's and the problem persists. Any idea what the problem might be?

Maybe its the earpiece flex problem

Now the phone is on mk2 rom and i have no sound whatsoever. When i try to make a call, it hangs. When i try to play some music it says "sorry the player does not support this type of audio file"
I am very frustrated because i have been searching but couldnt find a solution. I cannot flash any other file e.g. mk2 to NB1 or any other MDL rom through odin. I used *#0*# to get to the hardware menu and tested speaker but it doesnt do anything. I still think its a software problem because phone is not able to make any calls either or play music files and hangs. I would greatly appreciate help.

Flash the modem back to a newer one. It is known that if you put an old NON-HLOS with the 4.4.2 bootloader that you lose sound.

Isn't the modem the same thing as the baseband? If so I have NC1 as my modem and can't find a newer one.

I have a similar problem with my speaker...

When in Android will played a sound (screen lock, music palying, dialing...) on the speaker come out only "tic"s... for the duration of sound... Then speaker will stop... Any ideas?

If the phone is stock and not rooted and you have not made any modifications on it then I would return it
to where ever you purchased it from and get it exchanged.
If the phone is rooted and it has a custom rom then I suggest to odin flash the stock Samsung 9505 rom
and that should solve the problem.
Good luck!

As suggested, if you are stock then you probably want to go to Samsung support.
But if you have rooted and installed custom kernel then it could be that.
I had that similar issue, sound disappeared sometimes but came back if I shutdown (not restart) my phone for 10 sec and start again.
If you have similar issue then it's caused by custom kernel. Might want to switch to another kernel or stock one.

Apparently this happens if you flash a newer firmware without the new baseband.
If this is the case you should flash a full firmware (read up on the Knox stuff first though)

i tried to turn on the noise reduction button and now the other side can hear me and i can't hear them.
there is some other setting to switch on or off ?
this phone is not rooted.
and the receiver speaker is working, i tested him using the *#0*# command.
and when my friend turn on the noise reduction button on his phone he can now speak while the phone is on speaker mode.
my friend phone is rooted and now its work to him.
