Can BT Audio issue on custom ROMs for Curtana can be fixed? - Redmi Note 9S / Note 9 Pro (Indian Model) Question

Hi Guys,
I had recently bought my new Redmi Note 9 Pro. I hate MIUI so I unlocked my phone, installed LRTWRP and flashed Evolution X custom ROM on it. But the ROM has one issue and it is big (atleast for me) - BT Audio - BT Headphones get connected but no audio is coming.
First I thought maybe it is a problem with my phone or headphones but when I read the same bug description in the LineageOS thread and in the Pixel Experience thread then I understood that it is a problem with the ROMs.
I want to know if there's any development going around to fix this issue or is there any temporary solution to it?
Thank You!

Your post is going to be buried here without any "good" answer. Better you adress it directly to the rom/dev section where these custom rom have devoted section.

[Q] rom that fixes a2dp skip / speed / pitch problem ?

Hi,
I have tried the official roms, villainrom 12 (excellent!) and cronos 2.1.3 (also excellent!). All have the horrible bluetooth problem of skips in the music, then a speed up/slow down that results in pitch changes.
I saw that Darchdroid got it fixed in the CDMA version and wondered if there are any roms for the GSM version that have it fixed too? Just in case I missed it!
Thanks
nobody in this forum seems to know how to fix it. I've asked but nobody knows, i believe the only sense rom that i never had the skipping was behnaam's legend port.
I am not experiencing this with VillainROM 12. Didn't have it with CyanogenMOD by Elemag either...
none of the Aosp based roms have this problem it seems to be only sense related. I've had this problem with villain,cronos,chocolateeclair,etc and nobody had any idea when i asked the same question. I actually am going to try to move the bluetooth firmware and files from the legend rom i mentioned above into another newer sense rom I just have to read up on resigning the zip, I'm a super noob to all that is linux.
Moved to Q&A as not development. Temporary redirect put in place.

Thanks, although I have also tried Cronos 2.2 (Froyo) that doesn't have sense and it still did the pitch/speed change.

Can I ask what car head unit or bluetooth headset you were using? It definitely does it with my Sony BT2600 car unit and both Cronos & Villainrom.

Could you let me know an AOSP rom to try that you know it works in please? - although I really like sense, I hate this issue and could live without it to get it fixed.
I'm pretty much a noob at this too but I'll help as much as I can!
like kosmiq mentioned Elemag's CMH rom doesn't seem to have this issue (I've used this rom alot and I have a 2010 Mazda3 and the bluetooth in the mazda is wonky at best and this rom works perfectly with it). As far as cronos froyo I haven't tried the bluetooth in that yet in my car but that is still an alpha development so if you need something more stable and complete then stay away from it, It is a great rom and the one I am running now but I am probably going to flash over to Maxisma's newest legend+WWE combo rom.
Good to see Maxisma back.

Problems with this smartphone

Hi, are there any problems with this smartphone? I'm coming from a Moto G4 with a screen burn-in issue, and I've read somewhere that this phone has it too, but I hope only some phones have it.
Also how is the microphone issue that some people claim it to have a bad quality? Has it been solved with official updates or only with community solutions?
Any other issues that I should be aware of?
I'm using xiaomi.eu rom right now, first time unboxing i got global stable MIUI8 rom, updated it to MIUI9. These 3 rom i haven't encounter any bugs related to audio, incall is fine, speakerphone doing good, recording audio or video went nice.
But i also try aosp custom rom, AEX, RR, even Xenon HD gave me the incall bug, nobody hear me whether i do the call or i took some calls.
the only way i can chat is using the apeakerphone mode.
i'm reading and searching for the same problem but no one did.
they had aosp custom rom running fine
do i did something wrong while flashing the rom?
only God knows

[BUG] Weird sound during calls on bluetooth

So i'm currently using kenzo as my main device. I had RR Pie installed until I came across this very annoying bug. I use a bluetooth headset for almost 4-5 hours everyday. It all worked fine until I noticed that calling using the headset was impossible. There is a sound like a machine gun is being fired in the background. It makes my phone obsolete.
I thought this was a bug on RR so I changed to Pixel Exp. and the same thing is happening. Couldn't find a solution on the internet but found a person who posted on the RN3 forum here :
https://forum.xda-developers.com/redmi-note-3/help/call-bluetooth-audio-problem-oreo-pie-t3836462
According to this guy, the bug is present in the oreo and pie roms. I haven't confirmed this myself. I am still downloading the stock rom to test it out. I guess it has something to do with the bluetooth modem. I will keep you guys posted on this. I hope someone replies to this.
UPDATE : I installed the stock rom. It's working. It's a bug on Pie and Oreo roms.

I flashed the Stock Rom just to test things out and it's working again. AOSP Extended doesn't have this bug ? I would be great if it doesn't.
Update : Flashed AEX, working fine.

Poco f1 (low earpiece volume)

Hi,
I have been experiencing low call volumes since few month's, exactly don't remember when this started and what was the reason behind it.
I tried out all the possible troubleshooting methods but nothing worked till now, but there is one strange thing that when i use whatsapp or any other internet voice call applications the sound is normal, loud and crystal clear. The only issue is with the normal calls.
I'm assuming it's because of the last update of miui 11.0.8, though i am not sure but i have strong feeling that the update is the issue.
I'm running MIUI 11.0.8 Global Rom and phone is not rooted neither bootloader is unlocked.
If anybody know what's the reason behind it or anybody has a solution for it, kindly share asap.
And if someone else is experiencing the same issue do share your feedback on this thread.
Any kind of help and feedfack is appreciated.
Thanks
i'm facing the same issue best case to wait for another update to fix it
Maybe you should try to clean the mesh that is on the speaker.
Mine mic totally "glued" by dirt ( I bouth used phone). It was hard to clean it without damaging the mic. Try isopropyl alcohol.
I guess its 11.0.8 update issue. Lets wait for next update till next year. ****ty China.
Do you guys think factory reset will solve this issue?
Did 11.0.9 update resolved this issue for anyone?
Guys one thing i can confirm is, its not due to the software. Thinking its the Miui,i rooted the phone and flashed Corvus ROM, but still the issue persists..

Have you tried flashing custom kernel?
Maybe that might help.
MIUI comes with Silvercore kernel and most probably Corvus comes with the same.
I suggest use optinus drunken or sphinx kernel
I hope its helps you.
I did flashed sphinx kernel.. even though it's better than previous but still is low..
Is your device rooted?
No.. by rooted means ' did I flash magisk?'.. no I didn't flash magisk..

If you've tried all possible methods on the software end then it might be an issue with hardware. If you have a local cellphone repair, might want to have it checked.
Actually after a day flashing the kernel, the audio volume has increased significantly.. guess the new kernel is learning the volume.. finally now I am able to use my poco F1..

Just an update.. the phone is back!!! Kernel was the issue. After flashing custom kernel microphone volume is fixed..
Which kernel did you flash?

I use to sing in Karaoke apps. What I noticed that this is the issue with Firmware itself. All Android 10 firmwares like 11.0.4, 11.0.6, 11.0.8 and 11.0.9.
Because when I flash any Rom based on Android 9 with any Pie firmwares till 11.0.5 I use to set my Mic gain to" -2" in Karaoke apps... As it's too loud.
But when I use any Android 10 rom with Android 10 firmware then I have to set Mic gain to "+3.5".. as it's too low and I can't hear anything.. and even after setting it up at +3.5 it's barely audible..
This is not hardware issue at all this is particularly firmware issue. Because it's working fine in Pie firmwares.
If you don't believe then you may experience it by your own. Just flash any Rom based on 11.0.5 firmware and see the difference in Mic volume in any recording apps or whatsapp voice messages or video calls or Messenger calls etc
I have got the same issue. Don't understand why the volume is low. Did you find any fix for the same?
you can use Franco Kernel Manager, in the kernel settings it is possible to change the sound. but it needs root, i always use it with all kernel and roms you can buy it on playstore very cheap.

I try everything , new speaker ,many kernels with speaker gain nothing help and still low earpice volume.

Ear/top speaker not working for calls on any custom ROM

Hello all,
I own a Xiaomi Redmi Note 9 Pro Global (joyeuse).
I have been, for the last three days, hopping between all of the ROMs available for my device (joyeuse) only to be disappointed by one very persistent and insufferable bug on each.
Quite simply, none of the ROMs I have tried, as listed below, have a working speaker at the top of the screen. Some of them don't have any sound whatsoever, others use the large speaker at the bottom, and this is not adequate for me due to a fundamental desire for privacy and noise isolation in public.
I have tried, to name a few, crDroid, EvolutionX, ArrowOS, AOSPK, Pixel Experience, Pixel Experience Plus, and Pixel Extended. These are just what I can remember, I have tried more than this.
I have also attempted using the myriad of custom kernels available in effort to mitigate this issue. None have worked.
I even tried to flash over the ROMs with official firmware, and I thought about flashing vendor images from Xiaomi Firmware Updater but hit a dead-end, because I do not know how to properly flash the image.
Any assistance with this, or suggestions for a good ROM or kernel to solve these issues would be HUGELY appreciated, because at this point I'm considering buying a new phone for better ROM support.
I've seen reports of this bug since the device launched. It was listed in one of the weekly bug report threads in the 'mi community' app/forum. It had a status update saying the bug was in the chipset and xiaomi was awaiting a patch from qualcomm. The thread has since been edited and the update removed. That's all the info I have

yes I have the same issue after I upgraded to MIUI 12.5 - it's awful. I am still on sotck and was hoping to flash to fix the issue but it looks like other ROMs dont fix it. So I will sty on stock until there's a fix.
what. a. pain !!!!!!
Same issue for me. Currently running evolution x on my Redmi note 9 pro. This is a great phone, but this bug is driving me crazy. I haven't tried any custom kernels, but from what the original person said, it didn't help. Interesting. Does anyone know if this issue affects the Redmi note 10 pro? I'm debating on getting that but want to know if the Redmi note 10 pro has the same issue. Ideally, I'm looking for a phone with good rom support, and has dual sim, or esim and a micro SD card slot.
Any update on this? I'm on a joyeuse as well with the same problem.
I found a solution, please read here and let me know if it works for you.

It worked! Thanks! The only strange thing is the first test call after I booted up the phone, the earpiece was finally working properly but the loud speaker wasn't working properly when I put the call on speaker. But on the next test call everything worked fine again.
Glad it worked for you. I Have no idea why this works, or what the bug really is, but i'm pretty happy to have my phone working again.
