Audio leaking from headphones to speaker - Xiaomi Redmi Note 4 Questions & Answers

As tittle says, if you are listening to anything via headphones, and you receive a call, or adjust the volume of ring or alarm via sound config menu, your music will leak as soon the call stops, or the audio adjust rings out.
this can be very embarassing and annoying, as i tried with different headphones and a lot of roms (miui 8stable/beta, miui 9,aosp/Los based, xiaomi.eu and on top of that, different kernels)
(this is different from audio leak when you take a screenshot or use camera when you are on customs, though some roms already fixed it)
Try to reproduce it by yourself by putting some music and putting up a fake call with some APP from play store, or adjusting volumes from settings sound tab.
if you have this problem, comment below.
As i'm pretty annoyed with this, and cant fix it, i want to know if are more ppl with this same problem
Edit: after trying multiple times, ONLY stock stable miui (8.2.10) doesn't have this problem, would be nice if we could fix this on customs and i would be willing to help.

[Q] Audio Issues w/ DSP Manager?

Anyone else have issues using DSP Manager at high volumes? The issue happens when using the phone speaker or headphone jack (didn't test bluetooth) and setting volume to ~85% or higher. The resulting sound is a lot of high pitch squealing that I imagine would be similar to what you would hear with a decoder issue.
To replicate the issue:
1) Launch DSP Manager, choose Headset (if you choose headset, I wouldn't put your headphones on for this test...or if you're running a line out to a stereo receiver, turn your volume all the way down) or Phone Speaker and disable all effects or select Menu, Reset.
2) Play any mp3 or streaming audio (ie Slacker, Pandora), adjust the volume to be within 1-4 clicks of max.
3) Go back to DSP Manager, enable Equalizer, and then adjust the low frequency slider (leftmost slider) to be above 0.
4) At this point, the sound issue should be noticeable if you're experiencing the same issue I am.
If someone can please test this and confirm they have the same issue I would appreciate it. I didn't find any other reports of this issue, but if it's a known problem, can someone please point me in the right direction to resolve the issue? I've tried this on 4 different ROMs (I think they may all be Cyanogen based) and I have the same problem with all of them.
Thanks in advance for any input.
Sorry man I couldn't replicate it on Nonsensikal 8.8. Used Pandora, set volume to within 2 clicks of max, and set <100 hz to .2 .4 and .6. Didn't get any kind of squealing. This was on phone speaker. I have had weird DSP issues in the past though. Just didn't care enough to try it on all the froyo roms.

I have the same exact problem. I cant even move anything without it going crazy. im running CELBFROYO 2.9
Thanks for your feedback guys, I'm going to try out Nonsensikal 8.8, will report back later.
Edit: I tried Nonsensikal 8.8 and still had the audio issues. Did a little research and I thought maybe I was experiencing "clipping". I don't consider myself an audiophile so I wasn't really sure if this was an accurate diagnosis of my issue. This lead me down the path to try out the Mixzing app since it has a built in EQ. Since the Mixzing EQ only functions on audio thru the Mixzing player, it's not an end-all solution since I find myself pulling up Slacker when I want a change of pace from the mp3s I have on my SD card, and the Mixzing EQ does not function for streaming music.
Anyway, I found the EQ in Mixzing to be quite helpful as it appears to actually detect when clipping is occurring and notifies you by change the EQ bands to red. The clipping I experienced thru Mixzing is not comparable to what I hear when using DSPManager. The Mixzing clipping results in the audio cutting out for a given frequency range - for example when clipping occurs when a bass drum is playing, you don't hear the full range of sound of the bass drum, the low frequency is cut off. What's also noteworthy here is that thru Mixzing, I was able to rectify the clipping issue by simply re-adjusting the sliders to their previous positions and the sound output was corrected. Whereas with DSPManager, resetting the sliders didn't fully resolve the audio issue, I was still able to discern a high pitch whine especially during quiet portions of a song until either the song ended, or I disabled the EQ. If this were related to a clipping issue, I presume the squealing I hear would go away when I reset the sliders to their previous positions, since the squealing persists, I think it's probably a decoder issue.
Something else I learned here, perhaps already evident to other users, is that for each frequency band you adjust in Mixzing, it requires additional processor resources. This might explain why the Eris (not sure if this plagues other phones) struggles here. And on that note, I was using my Eris to test the waters and help me determine if it's worth rooting and dropping a custom ROM on my Incredible. Since this sounds like it can potentially be a resource issue, and I haven't found other users on different phones experiencing this issue, I guess I'll take the plunge and try a custom ROM on my Incredible.

Ringtones & Notifications play through speaker instead of headphones

On my Nexus S with ICS 4.0.3 I noticed a behaviour which I find a little bit annoying and useless. When I have headphones plugged in, the output for Music & Games etc. goes through them, as expected. However, Ringtones & Notifications, as well as Alarms, still go through the speaker. So when you listen to Music in the Subway, or wherever, and someone calls you, the Music will suddenly be muted via the headphones and then the phone rings through the speaker on the back, instead of your headphones.
I asked a bit around and found out, that it was always this way in Stock Android. At first I thought there may be a problem with my phone, since I didn't have this behaviour on my old HTC Wildfire. But apparently HTC deliberately changed/fixed this behaviour in HTC Sense.
Is there any way to fix this, without switching to another ROM completely (I hear CM fixed this as well for instance, but MIUI does not)? I'd like to stay at the Stock ROM for now, may be with some additional changes/extensions installed through ClockWorkMod.

This happens as well on my skyrocket and t989, is there any fix?

[Q] CM11 Samsung Galaxy S3 GT-I9300 No notifications sound

Dear All,
Hope you can help me with my bizarre issue with CM11.
I have no notification sounds (calls, sms, mms - none) playing when call or text arrives. The speaker works fine as the music plays. From there, it gets only weirder: I have no sound of "beep" when moving the volume slider, no sound of the screen lock or charger plug-in also.
What is interesting, when someone calls a very, very silent "beep, beep" is audible closely to the phone, similar to the one that usually informs about the second caller calling while you're already talking.
Vibrations also do not work.
I have tried other nightlies, it is the same (started on cm-11-20150614-NIGHTLY, tried the one dated 2015.07.06 and 2015.06.07 to no effect).
Tried to apply some caller application, no effect.
Unplugged notifications from other sounds volume at sound settings, no effect.
Tried uninstalling lately installed apps.
Tried changing the ringtones.
I really had zero issues with CM11 and find it a fantastic way to prolong the life of my sgs3, however this issue is annoying af. Could you kindly please share some insight on that, as the internet search does not help.
Also, this is my first post, lurking a lot, registered due to not finding answer anywhere, if I chose the wrong category do not go harsh on me guys

Speaker broken? /ringtone problem?

currently on AOSP 5.1.1 there is no volume at all, can't play music from music app or youtube or anywhere else, the problem started off with no volume when people try to call me (yes the ringer was on full volume and sound), after a few days the volume started to not work on facebook videos and youtube and other stuff, the phone speaker works so when i notice that someone does call me (vibrate works but don't really notice most calls) the speaker works i can hear the other person (mics not broken), loud speaker doesn't work, is the actual speaker broken? how do i go about a replacement if so, have looked a lot around the web and cannot find parts other than screen and digitizer. I have tried flashing the firmware with twrp and sp flashtool, formatting everything and tried different versions of firmwares and still the same not fixed, also tried custom roms... any suggestions?
I have flashed my phone to stock Android 5.1 as this is the only stable version and all is working well apart from the microphone. When I receive a call the ringtone occurs and i can hear the other person but they can't hear me. I also tested the mic on google but nothing happened.
However, I downloaded TestYourAndroid from Play store and the mic works so I know it's got to be a firmware issue.
Also I can record voice by recording app
If you can help me I would be most grateful.
Note. this is android 5.1 lollipop so it doesn't have full permissions mode, I can access permissions for downloaded app but not for system app such as "phone" is.

Question Popping/crackling sound during calls on multiple apps [SOLVED]

Every couple of minutes I am getting a loud pop/crack sound during normal calls and the same behaviour on Whatsapp and Viber calls.
I tried both on speaker and without and the result is the same. I am running all the latest updates. The adaptive sound is disabled.
Also tried Stealth Audio Player to hear both the external and internal speaker on Youtube videos and I can't reproduce it except sometimes it pops when a video is started. I also tried recording my mic and it sounds clear without this popping.
Is there anything else I can try to fix or debug this issue? It sounds like it is trying to record or adapt the sound while on call even if the adaptive is off.

This kinda sounds like the problem I had, but ALLLLL the way back to my Pixel 2 XL!
If you're rooted, you can try what worked for me below -- although, I'm not up to date with Viper4Android (V4A) and I believe it's either EOL or is in the process of being updated to work in x64 architecture or there are newer updated branches or something... But if it's possible to lower the frequencies, you might luck out like I did on the taimen...
I Found a Speaker Distortion Fix
Like many, my phone has the lower speaker distortion on speaker phone calls and general audio, like YouTube, when turned up high. If you are rooted, I have found a solution to all situations except speaker phone calls. I installed Viper4android...
forum.xda-developers.com
Thanks for the help. I can hardly hear any issues while on youtube. There is noticeable pop when videos ending or starting. Some people are reporting motherboard issues with Pixel 7 leading to similar problems. I am trying to find if it is a hardware or software issue.
After further investigation it looks like interference. If I disable the mobile data and WIFI it seems to be a lot better. After 16 minutes call it was a very faint pop if at all. Does it sound like it needs a motherboard replacement or a future patch might fix it. Update: still happening regardless of connectivity on both the inner and outer speaker. I am going to RMA for motherboard replacement.
