Bad call quality - cracking sound on high volume - Galaxy S6 Q&A, Help & Troubleshooting

Hello, I have an issue with cracking sound on my Galaxy S6. The problem starts when in-call volume goes above 80% (cracking sound becomes audible). It sounds like some resonance or like it was something loose on the earpiece. I'd like to know if it is "normal" for this phone?

[Q] Earbuds excessive call volume

So I only noticed just now the Nexus 5 did not come with any earbuds. I have been using some cheap Skullcandy earbuds for music and they are decent enough to block out transit noise and play music at a moderate volume. However when I try making a phone call, at the lowest volume the sound is just ridiculously loud. It is painful for me to attempt to listen to more then 10-15 seconds of call audio wearing these. I also tried with my Galaxy Nexus earbuds, and it's the same story.
Has anyone found a pair of earbuds with mic that delivers gentle, quiet call audio at the lowest call volume of the Nexus 5 on stock ROM? Failing that, is there anything I can do to decrease the headset call volume further than the volume control will allow?
Bump, anyone else experiencing this? It shouldn't be deafening to make a phone call with earbuds...
OK I'm going to bump this again. It got WAY worse on 4.4.1. While I appreciate the volume boost for the phone's speaker, the earbud volume situation is out of control. The lowest volume setting on music, in a quiet room, is the loudest I can tolerate on earbuds - no option of turning it down lower. The lowest volume setting on phone calls is earth-shattering on earbuds - completely unusable for conversations unless I want to go deaf.
Is there ANY way I can force call volume down further on the headphone jack? Hacks, kernels, Xposed modules? I really don't want to be locked out of being able to make calls with earbuds.
All perfect with 4.4.1, skullcandy have a very bad quality earbuds, better buy sennheiser.

The sound quality is great, it's just too damn loud. Same with the earbuds that came with my Galaxy Nexus.
The call volume is ridiculously out of proportion with music volume. That is not the fault of the earbuds. The OS should not be pushing out call volume significantly louder than the music volume at a comparable setting.
OK, so a friendly individual in the Franco thread directed me to this:

I simply used the same instructions for the mod but reduced the number rather than increase it. For call volume, the value that I changed was under path name "voice-headphones". The original setting was 20 and 20 for HPHL and HPHR volume. I turned them down to 05. I thought I heard a reduction from 20 to 10 but did not hear any further reduction from 10 to 05. Then I also tried reducing the RX1 and RX2 digital volume. I tried taking them from 84 down to 64 which was maybe a bit low, so I settled on 70. At that setting, the loudest IVR systems I've reached on the phone are just right at the lowest call volume setting, and I still have room to raise the volume in noisier environments.

Speaker noise at low volume

Hey everyone!
Today i've noticed that when I turn down the volume to the lowest level, the volume level before muting the phone so you can barely hear it, I can hear a static noise coming out of the speakers if I put it veeery close to my ear. This happens when playing games, listening to music or doing anything which has sound. If a turn up the volume i cant hear it anymore.
Is it happening to everyone? Is it normal?
Thanks in advance

I haven't tried it (my background is a bit noisy to test right now) but I think I've read that its a software issue and not hardware. I can believe that its software based also because you state that it only sounds that way at low volume.

[Q] xperia z3 speaker problem

Anyone here having problem on the speaker? When i test ringtone in sound picker and try classic phone or cassiopeia there something weird sound in my speaker
Yes I do too
What kind of sound? Like a distortion you mean? At maximum volume?
I think he means that vibration or something loose like sound that comes on certain frequencies. I only get it in calls at full volume sometimes but not with music playing.
Ah yes for calls it might happen. But if you are listening to music with a high bitrate (high quality), you should not hear any other noises. Because low bitrates (low quality) music can make weird noises at high volume.

Some Problems

Hi all;
Problems with my OPO:
- Sometimes the sound from the speaker is charged slowly so that the other end are barely heard. Other times, though the conversation begins with a clear sound in the headset and high fidelity shortly quality decreases sharply, so that the listener becomes even harder to understand in what he says; sound in speaker sounds like the other one ... as a boiler.
- Lately, increasingly more often, to initiate a sound applications (games, sound email or call sound) sound blocks, generating a disturbing sound, sharp or rattles like not disappear until I restart the device .
You know what solutions?

Crackling sound from both speakers

i think it started recently
while i hear music especially when skip tracks (or sound stop&play) even in the menu of the phone is abit different in some apps
when i turn down the volume you hear it less "loud" (sound like blown speaker)
maybe software related? (i hope not hardware)
did it happen to anyone?
