v8 soundcard + phone + pc sound issue - Redmi 9 / Poco M2 Questions & Answers

this is my setup.
v8 soundcard cables = earphone, condenser mic, charging to pc and live 1 to aux redmi 9.
redmi 9 cables = aux to soundcard live 1 and usb to pc
when i put these 3 cables(phone to pc, v8 to pc and phone aux to live 1 v8) at the same time. im hearing a heartbeat sounds error. its kinda 4bit bass sound ground or ground loops.
i never hear this sounds to my oppo and iphone.
is there anyone encountered this problem in redmi 9?
is there someone know what is the issue? is it MIUI or our device?

i would like to share this.
from miui 11.0.2 EU version i heard the loud static or ground noise when i connected the 2 usb cables to computer, which is my redmi 9 and v8 soundcard and also the cord from live 1(v8 soundcard) to redmi 9.
i tried to update my version 11 to miui 12.0.2 EU via OTG and this was happened. it lessen the ground but the ground still in there.
i found this, i dont know if this is a problem.
the difference with MIUI 11 and 12 regarding in charging time.
MIUI 11 is more faster than MIUI 12 if you charge it when the phone is turned on.
Is there anyone here notice this?

White noise/hissing in the background while listening with headphones.

Hi, so a few days ago white noise appeared while listening to for example music. Headphones aren't faulty, checked them on my computer and other phone, their are good. But the thing is, if I make phone detect my main headphones without mic they work perfectly fine but in-line controls don't work. It pretty much more noticible in lower volumes, in higher volumes you can't hear it pretty much, only when music is like fading in the end. You would say just listen to higher volumes, but I'm a type of person who notices a thing and can't unotice it.
Right now I'm on MIUI 7.9.22 (MIUI9)
This seems like a common issue with Xiaomi phones, be it the Redmi Note 3, Redmi Note 4, now the Mi 5 and the Mi A1.
What on earth is Xiaomi doing to the headphone jack?
I hear rooting and changing some stuff can fix it: https://forum.xda-developers.com/redmi-note-3/how-to/fix-crackling-static-noise-headphones-t3453004
I fixed the problem just by flashing back to MIUI 8.

Headphones volume is extremely low

I have a big problem with the Mi A2 - it's really quiet using headphones (through the stock adapter). It's not headphones problem. Now, the question is, is that because of the software or maybe because of the crappy adapter? I need the people from EU country to speak here because maybe it us because of the stupid EU law.
Noticed this too. You get a slight improvement with viperfx and master gain /xloud , but that's all I found out.
Now, even if I am a pretty solid fan of Jack + high end headphones, we are in 2018, moving to BT headphones with Bt 5.0 is the way to go. On this matter. Having aptx advertised and not able to use it without build.prop tweak is a more serious matter IMHO ??
Still Loving my mia2 everyday more tho. This thing is getting faster everyday and having the governor set to ondemand + touch boost disabled make it fast as hell and crazy battery performance (getting solid 5-6 hours SOT)

Same problem.... headphones were pretty loud on my old Mi4... now its really low. :/
What do you mean with "touch list disabled"?
Thanks!

I love my Mi A2 too but I swear I can't listen to the music because the volume is so damn low. While you are rooted, could you send this file - system/etc/mixer_paths_tasha.xml and this system/etc/mixer_paths.xml? I am sure low volume can be fixed by editing these files.
They can be stored in this place too - vendor/etc

Where is this option?
Solution?
This problem is something I struggle with too. Might it be the usb type c adapter to aux which is the problem? Can anyone try with a different adapter and report back? I am using Xiaomi mi in ear pro headphones. I need to use max volume to have a volume which I consider medium.

I have Xiaomi Pro too (HD). Sound is so low... I have bought xDuoo X3 II and will use it as a Bluetooth receiver.
Mi A2 Bluetooth Audio volume low too?

I just got my Mi A2 and the audio volume seems very low when Bluetooth paired to my cars stereo. Maybe halve the volume of my old LG phone. Very weird since the audio volume thru the Mi A2's built-in speaker is VERY loud.
Stock dongle's output is slow. Get some other 3rd party and sound will get louder. I have bought and its sound is quite louder than stock's one.

I just got google's newest dongle, it is good. The volume, while not overwhelming, is certainly loud enough with music. Dynamic Range seems quite improved also. I figured for 12 bucks, not much to lose. But turned out improvement for sure.
Mi A2 audio quality
I am currently using the stock dongle and mi piston fresh earphone on my Mi A2 for music. The audio quality is really poor. There's noise and audio is muddy. Is anyone experiencing this and is there a way to improve the audio quality?
I used the headphones of the leeco le Max 2 type c and it sounds wonderful ... but when using the adapter for my headphones Xiaomi sounds very slowly

This doesn't help at all. You'll still end up being stuck with SBC or AAC codec.
I recently converted my phone to Mi 6x and flashed AospExtended v5.8 Rom. Now LDAC is working perfectly with my sony wh1000xm2 headphones and volume output from stock dongle has increased to normal levels. So finally I'm able to use my MI A2 for listening music and I don't need to carry my old Moto X play with me just to use spotify.
I don't think problem is low quality of stock dongle. After all it is just simple adapter and it shouldn't have any or very little difference on audio quality (audiophiles may have different opinions). And I also had very low volume via bluetooth on stock rom.
I'd really love to use the stock rom because the stock camera is much better for day to day use than these buggy gcam ports, but low audio output makes it impossible. Mi a2 is great phone with ****ty firmware and I don't have any high hopes for Xiaomi to fix these bugs. Maybe in the future when development really kicks in we got rom wich is capable for music and photos.

So can someone confirm if this is a problem in the type-c to 3.5mm adapter? If i buy a usb-c earphone or a third party adapter the audio will be loud?
I'm really waiting for someone at XDA to comment on :

Question redmi note 10 pro max problems.

Hello everyone
For past 1 month i have been using mi note10 pro max and slowly i am having issues with my phone.so plz help me to solve these problem
Screen does not give proper respond while touching the screen in 60hz aswell as 120hz(sometimes)
stereo speaker sometime works and sometime it wont.(tried switching from mono to stereo and vice versa)
I have been using different types of earphone and earbuds yet i am not able to hear stereo sound(only in 8d types of audio) other music works fine as stereo.
the equalizer preset given my redmi for earphone s are not ok i was wondering i could change it.
Thats it.
Thank you in advance
Since it is under warranty why don't you visit an authorized service center. May be they will apply a fix for these issues. And you are still under the warranty period. So it would be possible
i also wanted to ask whether the problem in redmi note 10 pro max of battery draining will be improved or will it be draining as it is draining now bcs i think downgrading the phone will not be the issue and it should be optimized by the company itself
pls tell me
