Serious audio issues, can anyone else test? - Xiaomi Mi 4C

Hello, it seems im experiencing the exact same issue as here: http://en.miui.com/thread-81318-1-1.html
I tried latest MIUI / CM12.1, can anyone else confirm it? Is this a software issue? Any fixes possible? It's extremely annoying..
The problem with sound when it's played with headphones on LOW VOLUME. (especially with in-ear plugs with good noise cancelling like Xiaomi Piston, it's less noticable on other types of headphones)
It is VERY noticable in quiet music or when listening to speech without background music like podcasts or audiobooks, or when the music fades out. I would describe it as hissing noise with a lot of distortion. (just listen to some audiobook to test)
With loud music it's less noticable because music overlaps the distortion.
The problem is the same with the speaker but it's much less noticable. (you have to put speaker close to ear to hear it)
Can anyone test it on your phone? :good:

Can anyone check it on their phone please? Maybe it's just mine and i will need to replace it..

I can confirm it, there's a little bzzz but i can barely notice that, so it's not a big problem for me because i always use vibration mode and also i usually don't listen music with the phone...

Guys you can confirm the issue here to bring this to the devs attention: http://en.miui.com/thread-201506-1-1.html

I need to test some more but it seems CM13 fixes the issue...
MIUI, CM12.1 = audio is as bad as explained in first post
CM13 = Crystal clear audio

[Q] Are there any sound quality issues beside speaker?

Hello,
the question is in the title : do you have sound quality issues throught hearphones like noise , artefacts...? It seems I have some random buzzing noises like a stuttering but I can't find where it could come from.
Nope, my headphone clarity is great and the speakers are about 50x better than nexus 4

None on my end either and personally I don't think the speakers are THAT bad.
I dont know what's causing this, it's the problem with random defects...
I managed to reproduce the issue : when I make a bug report from develloper option while listening to music.Bluetooth seems unaffected.I made a video of the problem: https://www.youtube.com/watch?v=6XZSef6fuKU
any ideas?
thanks
The speaker is a lot quieter and not as clear as my S2, but it does the job.. Only use it so often.
But, I don't know about you guys.. what's quite annoying is that in apps that force the screen counter clockwise when viewing horizontally my hand covers the speaker and I have to adjust my holding position to hear sound. It seems strange that they didn't place the speaker and mic the opposite way round.. (maybe for calls.. I don't know..)
Also annoyingly, there's such a simple solution, if only somehow all apps could be forced the opposite way then the speakers on the top left and is never covered maybe it could be incorporated into a custom rom?

Loud hissing when capturing video

Hi,
When capturing a video with the M8, I've noticed a distinct and loud hissing sound when playing the video back, even when there is no sound in the background. I've compared this to a friends M7 which doesn't have the hissing sound at all. Has anyone else noticed this? Thanks.

unless you are holding something in your hand that could cause RF interference it sounds like you got a bad phone....

Low in call Volume of Ascend Mate 7

Dear All,
I have Mate 7 MT7-L10 but the call receiver volume is too low even if it is set at its maximum. Can any one have some mod to increase its volume??
Please help.
The Mate 7 is very loud. Volume enough already two-thirds. Surely that is not defective speaker?

The Mate 7 has a low volume output even when all volume controls are set to maximum and the in-pocket mode is set. I found this to be true on the in-store demo models (3 units in different stores and countries) and my own unit. The ring volume and alert volumes are also lower than they should be. If one is in a quiet environment ok, but in a noisier environment, they are way too low. Perhaps Huawei should tweak the appropriate firmware to manage this problem.

Good idea. At one point it appeared as if someone from Huawei was monitoring these XDA forums. It could be useful for them. Note. Otherwise I am very pleased with the Mate 7.

Yes very right all other things are perfect in this model except low volume which can be managed by tweaking through firmware. As I have a Note 3 and was planning to buy Note 4 but I am quite satisfy with Mate 7 except this low volume issue.
I agree that the volume is low compared to other high end phones.
Has anyone found a solution yet to increase call volume when using headphones on the Mate 7? I am barely able to hear the other party during calls, even at the maximum setting.
I don't know what is the problem in your unit. Believe me this phone is the highest volume, I have ever seen. I have to reduce the volume so that other people don't listen to conversation even without speakers off.

Using the headset or the earpiece? I'm talking of using the headset. The output of the 3.5mm jack is far too low.
I found a solution, btw. I deleted the /system/etc/audio/codec folder and tadaaa - output appears at least twice as loud, both during calls and when listening to music. Previously, I had to set my car's stereo to volume setting 25 (I usually use 15 when listening to the radio) to be able to hear something on the autobahn, now I only need to set it to 12-15.
So there definitely was an issue with output on the headphone jack, and for my device it is now solved.

Alright I thought you saynig earpiece.. or loud speaker...
but you mentioned you deleted codecs in system audio ..
now go and check your video recording and you will hear distorted audio
check pls and let me know..
i know this trick long time ago and I did it on earlier phones (i think on lg) and audio in video recording was wrong.. don't remember now if it was left or right

Everything's just fine. I know it's always a risk tinkering with the system, which is why I made a backup of the codec folder just in case. But so far, no issues at all in daily use.

Headphones volume

Anyone else is struggling with SUPER LOW headphones volume? Before OP6 I had HTC One M8 which was LITERALLY 3 times louder. I am using SoundMagic E10c(cable, jack) and I am wondering if similiar problem exists for BT headphones. Need some way to have music with decent volume, since I am listening to music basically all the time.
Any way to fix this?
That's true. I hope that there will be a Sound mod in the future

The same problem doesn't exists in case of BT headphones for sure... Its just bad with wired one's, really underwhelming! Waiting for some good audio mod to maybe help fix that issue if possible.

My earphone volume is fine. Using non standard music player/ equaliser and good bearphones
I don't know why people say it's quiet on headphones I've 3.5 jack. I use bullets V2 from OnePlus and the volume and quality are fine.

I haven't noticed a difference in the sound over my LG HBS850 (Bluetooth), and I haven't tried my 3.5mm cable headphones yet.
I have OP6. After reading the complaints here checked with different brands of earphones. The sound is really loud and clear. Even at medium levels I have sufficient loudness. Equalizer too works well. I checked the earphone audio in Player Pro music player, Saavan streaming music and YouTube. I am very much happy with what I hear in terms of loudness and fidelity. I don't think the mentioned complaint is true universally.

I experienced the volume loss as well. When using the phone in my car I have to adjust the radio by almost 10 ticks (from volume 18-20 to up to 30 now).
Yesterday in my car with the oneplus 3 no problems, but the 6 has some very low volume settings. It's kinda frustrating at this point, the volume sucks and the quality doesn't match up to what the oneplus 3 could produce. I think it has something to do with the equalizer that oneplus 6 now offers. This morning while trying to adjust the settings I've downloaded the snapdragon equalizer on top of the baked in equalizer and that seems to kinda do the trick (boosts the volume by a bit).
Oh boy, same here. Using a pair of M50x's, they don't need much power to get going but I've noticed it's not as loud as my 3. I have a fiio K1 amp but didn't work on the 3, figured it might! work on the 6 but nope! so I guess I'm stuck using a amp with the headphone jack.
Oneplus really needs to improve their audio output power, that's for sure.
So I just noticed something. Music is actually fine and loud ONLY when i am choosing ringtone. Spotify/Google Play/VLC etc. all is silent, even after installing Viper4Android it's still to silent.
I agree, the volume of the headphone jack is very low and the overall sound quality is bad. My HTC one A9 is brilliant when using audio files from the jack. It's loud and clean but the OP6 is too low and very bad sounding. Not for audiophiles. I tried with Viper and it's the same.
I felt low volume intially , but after 5.1.8 update I think the volume is good. (May be its just my feel ?)
I tried with ATH M50x and samsung stock earphone.
With the filo e7K the sound quality is good enough ...

I have cheapo ear buds with 16 ohm impedance, just like yours. Anything above 80% volume is uncomfortably loud. Perhaps your unit is defective?
chiming in, no issue here, brand new, white OP6... I'm smitten
for me volume too low even with viper4android
Massively loud with black player, amp and good bass earphones, even the speaker is much louder than my HTC 10
Give ElementalX kernel a try, I've flashed it and boosted my amp output. It helps! with viper4android I don't really need an external amp anymore. But.. it's still better

Same here until i have changed the headphones value (Rx1 and Rx2 mix digital volume) on the "mixer path tavil.xml" file located here : Root/vendor/etc
90 is perfect and you will see a huge difference ! Try and let me know. If you prefere i Can also send you my customised file ?
Don't what y'all talking about, the sound over the headphone jack is so loud to the point I set it only at 60-70%... And the quality is great too, Had a nexus 6p and LG G5 before this one.. but i tried a lot of phones
This one is really loud with great quality overall

Galaxy Note 3, LineageOS 18.1, Volume Override

Hello,
I'm wondering how I might override the volume on my device in order to make the loudspeaker... louder. My device is rooted and has SmartPack Kernel app on it.
Any help is appreciated.
i am using this app. Hope this answers your question.

Well it did help and it has also made me realize how loud I listen to music with headphones on. My iphone which I use as a music player gets very loud whether it's the loudspeaker or using headphones. With the app you suggested I can tell the Note 3 is getting very old it doesn't handle its volume being overridden well, it sounded distorted and unclear (I had it at 5% boosted).
Oh well, I can live with how it is as-is.
Gave it another shot today.
I rooted the device and then flashed LOLZ kernel and with SmartPark have been able to up the decibels for the headphone jack and for whatever reason SmartPack's method doesn't distort the audio like the Booster app did.

Perhaps. I fear that my phone is going to be toast soon, the loudspeaker is starting to get that airy failing noise of a speaker sound haha.
I upped the decibel for the loudspeaker by 2% and the headphone jack I think to 3-4%.
BUT even before I did that to the loudspeaker it was giving me that failing sound.
