When I play FLACs on the One, sometimes I get a little crackling in my headphones. I'm pretty sure this is due to clipping because the power output of the phone isn't enough to drive my headphones. They're Audio Technica ATH M50s if anybody is curious. Is there anyway to increase the power output of the jack whether it be through a ROM/kernel/app?
Earlier today, I tried connecting my One to a portable speaker and the sound output was extremely low ( both the speakers and phone was at max volume)
But when my friend played through the speakers with his phone, it was all right. I didn't pay much attention to it.
Now after getting back home, thought I'd try once again, and when I connected my earphones, in the volume output is very low ( max music volume)
The phone recognizes my earphones, both the boomsound speakers work fine.. The only problem is with my earphone jack.
Does anyone have a clue why this is happening, and is it a software issue, any solutions
Just got my OP3T yesterday, and absolutely love it...EXCEPT that when I listen to music on (wired) headphones the volume does not go very loud. Even when I turn it up to the highest setting, just not that loud. And the headphones are plugged in all the way, they work with other phones, etc., etc. Anyone else having this issue?
You gotta plug it in properly, that was the issue with mine. It almost requires an unreasonable amount of force to plug it in or plug it out.
I use wireless bt headphone, and the sound is pretty loud, compare with the droid turbo, will try the wired headphone later

No problem with mine, turning it up more than halfway is way too loud. Best sound I've ever had from a phone.

What's is the impedance of your headphones? The higher the impedance the lower the volume, usually higher end/better quality use high impedance 32 ohm's+. My Sony's are 32 and are reasonable but still use my Fiio A1 for some extra umph! Might get the Fiio k1 and see what USB audio is like and get another pair of AKG's as they are my favourite sound signature.

Yes, I'm aware of this. Mine have been plugged in fully.

The impedance is 16, so that shouldn't be the issue.

Strange I get decent sound out the jack alone. What is the make and model of your headphones?

Have tried it with both Sony MDR-EX58V earbuds and Sony MDR-V8 over-the-ears.

Weird why not invest in a Fiio A1 or USB variant K1, I'm thinking of jumping on the USB audio to see how it is. I know that "it's not the point" but a worthwhile purchase if you enjoy music.
Mine is plenty loud. Used my Xiaomi Piston 3's all day with it.
Higher impedance means more control over your volume because you're basically forced to use an external amp/dac, doesn't necessarily mean better quality.
Same issue, loudest volume is about right for me, still, does not go as loud as my Nexus 5 did.
More than loud enough at 65% volume with my Audio Technica and Shure headphones. I ended up lowering the max volume with custom kernel.
You can always try the "Increased Headset Volume"-magisk module if you want louder headset volume.
Even though this phone has a 3.5 mm headphone jack, the audio output via the jack is terrible.
I have tested 3-4 different earphones as well as gaming headphones but still I'm disappointed.
Even on the loudest volume, the audio seems a bit on the low side.
Any solution for this ? or any workaround ?
Have you tried to push the hj all the way in?

Yes. Earphone fits perfectly in the jack. I said that the volume is low because I compared it with my cheap old phones. And the hj audio o/p was way better than nokia 7 plus.
It might be high volume warning. You don't see this popup if your screen is off and volume stays at the same low level. https://www.xda-developers.com/how-to-automatically-disable-the-high-volume-warning-without-root/
I recently got this smartphone, and one of the very first things that I noticed is that volume thru headphones is very low, this affects the 3.5mm jack, USB-C audio and even bluetooth. It is in fact much lower than on the previous Redmi 9 which I compared with.
Doing some measurements (by playing a tone and measuring with a multimeter) I found that if I plug a male to male 3.5mm jack to the headphone, it will play audio thru, however none of the settings for headphone will be enabled (meaning that the phone doesn't think that I'm using headphones) if I then connect headphones using an adapter it will play at full volume no problem.
The 3.5mm2 jack puts out 0.8Vrms when there is no headphone, and 0.25 Vrms when it detects headphones. (way too low for many headphones).
This means that the phone has a feature that lowers its max volume by 10 dB when using headphones, that is why it also affects bluetooth audio.
For those that want to test it, if you plug a 3.5mm2 extension cord to the headphone jack, and then you plug headphones you will find out that the max volume is much much louder.
Hopefully there is a way that I can remove that feature all together.
I already tried changing the region, disable absolute volume, etc. None of that worked.
Follow up:
I found that what causes the problem is the equalizer effect that Xiaomi added to the phone.
Every time that the smartphone detects headphones it enables the equalizer, the equalizer has a range of +10dB and -10dB.
They implemented the EQ in such terrible way that +10 dB is actually -10 dBFS and -10 dB is -20 dBFS.
So if I increase the volume at say 100 Hz, it is now able to output 0.8 Vrms at 100 Hz. However if I increase the volume in all bands the EQ does nothing and it stays at -10 dBFS. meaning the issue is still present.
There is no option to disable the EQ, it is just flat by default but they didn't add an option to turn it off.
Edit: I tried disabling com.miui.audioeffect thru ADB and while it was disabled, the volume is still low.
No idea if there is another APK that I could try.
