[Q] Sound CM11 CM12

Hello! I'm using jfxperias' Evo 9 rom and I love the sound I get from it via poweramp and viper4android. It sounds better than my dead and buried ipod classic did and it saves me one less thing to carry when I go out. Lately I've been trying pure cm11, cm12 and Resurrection remix roms but I don't get the same audio quality and sound levels on them as evo 9 which is kind of a disappointment. This phone is my daily driver and also my music player and I'd like to be able to use newer updated roms on it as time goes by but the sound output is just not the same on the ones I've tried so far. Does anyone else face the same situation here? I would appreciate it if I could get some pointers regarding this. Thanks!

Audio problems with MIUI

As a user of S8,S8+ and other android phones, my earphones work perfectly without any audio loss. Same with my PC. But with my redmi note 8 on MIUI, I have some audio loss. I can feel it in my ears :cyclops: .
What I have experienced is that with any AOSP 9 or 10 roms, the audio is perfect like any of my other phones. But with MIUI and every MIUI ROM I experience some kind of audio and bass loss ??
I really don't know if I'm the only one experiencing this. Let me know.
Also I've used on MIUI v4afx, JamesDSP, and Dolby but still they don't work as good as with AOSP ROMS.
Does anyone have an idea why this is happening and how can I fix this somehow ? Thanks.

Question [Q] aosp/linegae based rom that didnt have bluetooth delay

can anyone suggest any aosp/lineage based rom that didnt have bluetooh delay , i had tried crdroid , but it had huge delay on bluetooth earbuds especially when playing gamed , unlike miui based that only had tiny unnoticable delay.

The delay/latency is entirely depended on what BT Audio Codec is supported by both the phone and the BT Audio device (unless there's something wrong with the ROM).
"AptX" is recommended. Your BT Audio device may have its own app and a setting called something like "Gaming Mode", which would reduce latency.
Behind the Gaming Mode would basically be "AptX Low Latency" or AptX LL.
If you don't have such settings in your earbuds' corresponding app, and nothing is Bluetooth Settings, you can try and check the Developer Options and try and force a Codec..
AOSP ROMs can have random bugs, so the big delay may be just from that ROM. ^^

my earbuds had that gaming mode option , but the problem is when using aosp based it still had huge amount of delay.
had tried switching different codec from developer option but nothing works. i dont know if any other aosp based rom had that delay or not because i had only tried crdroid and one more aosp based which i forgot which one LoL!

Hm. In that case I'd do a backup and try an older version of crDroid or a different AOSP..,..,,,.,,..,,,,,,.,,..,,

I don't know if it is an aosp based rom but i am currently testing this https://forum.xda-developers.com/t/...elos-aosp-alioth-aliothin-09-05-2022.4392649/. Bluetooth audio lag is very low even lower than miui based roms.

Question Regarding AOSP and Dolby Atmos (or "Am I indeed limited to Xiaomi.eu?")

I've done few searches in the forum, just to affirm my thoughts, but I found only the points that lead to the other title of the thread, but I'll ask this frankly and clearly:
As a hardcore Arcaea player:
Am I indeed limited to Xiaomi.eu?
Or it could happen that an AOSP ROM can feature MIUI Dolby Atmos?
I'm pretty sure this is a "pick your poison" situation, as going AOSP (crDroid, to be frank, many thanks raystef66!) kills Atmos but going MIUI instead screws the UX, but I'm kind of unsure of which to pick.
If unsure, even with Moto Audio and external equaliser "Wavelet" kind of "patching" the audio quality a bit, it does not help the audio latency resulted from missing the proper audio drivers (a stark difference of 142ms just from losing Atmos), to which Arcaea is extremely sensitive, enough to urge a switch.
I'm sure I'll get some words saying I could just try this myself, and I'll agree beforehand; I just need to know how to manage a custom ROM and I could figure out MIUI Atmos. And then the licences for the ROMs, including my current selection.
If there's nothing I can do about this, feel free to autolock the thread if you must along with a Xiaomi.eu recommendation, since it just will be yet another "Dolby Atmos" thread on top of the existing pile...
alioth 12.5.6
crDroid ver8.4 (Android 12.1) 2022.04.08
TWRP 3.6.1-unofficial
(Special note: If I must be rooted for any potential solution, I could use methods to bypass CrackProof in Princess Connect! Re: Dive since I am also hardcore in that one. As of now CrackProof does not complain with the current crDroid setup, since I refused to install Magisk until required for good reason.)
EDIT: Auto-converts to emoji, yikes. I may re-edit again as I test.

Moto Audio sadly. It doesn't help--the latency is still there.
The problem is specifically about MIUI Dolby Atmos.

Hey, have you found a solution?
I'm in the same boat. Have you found an Non-MIUI Custom ROM with good Dolby Atmos?
It sucks that no one has ported MIUI Dolby Atmos yet. I wonder how much effort this would take. And if the audio driver or MIUI Dolby Atmos is proprietary.
I used to be on ArrowOS (which is lovely clean btw!), but I cannot deal with Default Sound. I got wayy too used to MIUI Dolby Atmos in Video Mode. But holy shít man, MIUI itself sucks major *ss...
I'm now flashing Xiaomi.eu 13 Stable until I find an AOSP ROM with actually good Dolby Atmos. Not the trash Moto Dolby or Razer Moto.

How's the Razer version (flashed with Magisk)?

It seems the reply above you has the same thoughts so I'm probably better off shaving some gigabytes sticking to Xiaomi.eu until MIUI Dolby Atmos is good to go...

How about trying ainur magisk mod? After trying it myself on miui to compare I never wanna use Dolby again.
Personally it's the best one I ever used - audio becomes much more crisp. It's distorted on miui implementation of dolby so I really don't think you'll get any further by yourself...

The problem isn't the crisp audio, but rather the resulting offset in Arcaea; an astounding 142ms latency. I kind of got the audio "patched" in crDroid with Wavelet before switching to Xiaomi.eu, but after I switched I noticed the horrid difference in audio latency in crDroid, gone/fixed in Xiaomi.eu. That's where the problem is.

This is what it's like on gsi
You will have to figure out how to adjust the app to use full screen tho... And the bottom but of screen is taken by the gesture pill.
Both are fixable via magisk modules
This is not headphones BTW , I have no idea what it's like with them
Another worthy mention is latest unofficial lineage 19.1 or try arrow tho idk if either stack well against audio latency... I'd try lineage tbh, I feel like it's more likely to be better audio wise and if the touch actually got fixed on the latest release like the dev said it probably should be decent.

For me the only problem with AOSP Sound effects were the Sound itself.
I didn't notice the latency being a problem, I didn't focus on that, but it may actually be a problem if you say so.
I use Bluetooth Headphones which naturally have a bit of latency, even on AptX Codex. As far as games are concerned I only play games like Dead By Daylight Mobile etc..
Dolby Atmos is a Surround Sound feature (Spacial Sound feature) and in my opinion Razer and Moto Dolby sounded like they *try* to make it spacial but instead make it sound virtualised. As if the Sound-bitrate got reduced.
MIUI Dolby is miles better, it can make music sound like it's more around your head (and not inside your head), when you select the Video-Mode. It's more immersive and emotional.
I also tried Wavelet and its paid features but I still wasn't happy.
With MIUI Dolby distortion is no problemo, at least for me. xd

Question Does Dolby atmos not working with games?

Eversince i bought this phone, i always turn on dolby atmos, especially the video preset. It makes the speaker much louder and fuller when listening to music and videos. But when launching games, the sound noticably weaker and flatter as if Dolby atmos is disabled.
I have tried to toggle Atmos from the QS button but no difference. I tried it on Spotify, the disabled atmos speaker sound is similar to when playing games. Toggling the "enhance audio" option in game turbo doesn't have any effect on sound quality either.
Does this problem always there for everyone or it is just my phone?
Here's my phone details:
Poco F3 128GB
Stock MIUI 13.0.5.0 SKHIDXM Stable

it should theoretically work. i'm not on MIUI, but in an AOSP Custom ROM with a Dolby Magisk Module and it works everywhere.

Oh no doubt that Atmos in custom rom will work everywhere or at least have work around
Anyone on stock miui have the same problem as me?

Yeah i have the same problem as you. Was trying to find a solution and i found your thread. It's most noticeable in games and ringtones.

Me too were trying threads that discusses this issue but surprisingly i can't find one. I don't know whether this some random chance that our phone just doesn't work or it's the same for everyone

Do you guys just use Stock MIUI ROM or a Custom ROM like Xiaomi.eu ?
I remember playing Dead by Daylight on Xiaomi.eu MIUI 13 (don't remember if Stable or Weekly), and Dolby Atmos definitely worked during that gaming-session!
I'll be going from AOSP back to Stock Poco MIUI. Will check for Dolby in Games.

I'm on stock MIUI 13.0.5.0 SKHIDXM. So far this has been happening since miui 12.5 days back when i first bought this phone in January 2022. Never rooted, never unlocked the bootloader, all stock.
