Problem detecting sim card, problem detecting network signal.

Can someone help me?
I saw that there are dozens of articles on the subject, but none gave a functional solution.
Details:
- I have a Vibe K5 (a6020l36 - latin version)
- The problem happened after I flashed MIUI 9 ROM available in this forum
- When I opened the "testing" screen (* # * # 4636 # * # *) I noticed that the radio's power supply is turned off, and in this menu I can not activate it.
- When flashing a custom rom with android oreo my sim card was detected but I could not get a network signal (in this case, when I tried to call someone a warning appeared to turn off the airplane mode, but airplane mode was never active).
- I already flashed the stock rom and nothing solved.
Thanks to everyone.

[GSI] [treble] Android 9 pie Bluetooth in call problem

I've tried all treble pie roms and in all are the same problem with Bluetooth in call sound. First I thougt it's a problem with my elephone u pro, but in the meanwhile I've recognized that the same problem exist in many phones.
I'll hope that we can support the developers with a payment if they fix this problem.
I am willing to pay up to 50$ if someone is able to fix this problem for the elephone u pro.
If there's someone else who wants to get the problem solved then please write here your payment offer.
But it would be a shame if people make an offer here and do not stick to it later.

Root first, then go to Vendor/Overlay/BluetoothResCommon.apk
delete it,then reboot,

1. You have to extract stock /vendor/etc/audio/audio_policy_configuration.xml and delete A2DP related section like this:
https://github.com/PixelExperience-...mmit/977444af69f10fc135d07e19f1e5f1183e73e9ff
then replace it (by root explorer or creating magisk module).
2. You also need to change /system/bin/rw-system.sh.
Please delete
Code:
mount -o bind /mnt/phh/empty_dir /vendor/etc/audio || true
and save.
NOTE: This works only on CAF based custom roms. It doesn't work on AOSP.

Hi
I've tried, but the changed and saved file
/vendor/etc/audio/audio_policy_configuration.xml
will be automatically deleted at restart.
The folder is empty after restart.
Any ideas?

Great job! Bluetooth In call is working.
I'll think it's not your development but for your know how to, I've send you 15 Euro.
Do you know also how to get Bluetooth audio music working?

By any chance did you get fully functional Bluetooth on the gsi rom or anyone else?

I'll hope so. 
 @AndroPlus has already fixed in call and may be he's on the way to solve audio also.

Has it been rectified in all builds
so is it safe to say that we can install the latest version of GSI provided by rom providers made in and released in march.
I would like to know that before i go ahead and transition over from stock to custom rom... mainly called PixelDust Pie rom version march

No, the fix needs device specific path and not all GSI has it.

I have the Razer Phone and have got either audio working or in call but never both... I am in the process of going through both audio routing files and see if I can combine them to get it to work, but I haven't messed with Android in years so it's taking more time than I anticipated to get caught up on all the changes you guys have made. The last time I built a rom was when treble was just on the discussion table. It really amazes me this bug has gone on this long, but maybe there's more to it than I'm seeing so far. I have seen some good devs working on this.

Enlighten me Please

Hey @AndroPlus , could you possibly explain how to go about it. I would appreciate the help. I have got a nokia 7 plus with pixel dust pie rom on latest version running. Where and what do i need to do to get it up and running on my phone. I need to get in call bluetooth running. Thats the only thing stopping me from using this amazing blazing rom

Bluetooth music also does not work with me. However bluetooth calls work, so its weird that music/audio is not working.

Bluetooth music also does not work for me, but bluetooth calls work fine. I'm using Arrow GSI with Mi Mix 3.

It's on resurrection remix pie, also headset over usb c is working. Only audio sound over Bluetooth is a problem. Do you've got a solution ir an idea what should I can try?
Btw do you have any idea how to control the led colours?

i still have no bluetooth calling on Mi Mix 3 on the @AndroPlus rom's so his solution definitely doesn't work for all devices.
furthermore there is still a bounty to get bluetooth working perfectly on vanilla android gsi's

Thank you sooo much! That´s all, I needed to do to fix my incall audio problem!
No changes in audio_policy.xml were needed - only removing this line from rw-system.sh

[FIX] [AOSP] Improve audio recording in video and calls

After devs changed fluencetype to fluence in build.prop for low incall volume, noise cancellation is so agressive. This fix solve distortion that you can find in your recordings.
- Tested in firmware 9.5.30
- Tested in Pixel Experience CAF and Vortex
Instructions:
- Download NoiseSuppresionMod.zip
- Reboot to recovery
- Flash NoiseSuppresionMod.zip
- Reboot to system
It MAYBE works in MIUI.
If devs want to fix it in their ROMs, they need to replace audio_platform_info and mixer_paths in /vendor/etc
Thanks to @Zile995 . He solved it in mido and helped me to do it in lavender.
Also, thanks to @letsmakecakes. He helped me to make flashable zip.

whats this for?

Wish I had this a couple of weeks ago when I was at Primavera Sound festival! All the audio of the videos i recorded was terrible :/
Anyway, can anyone confirm this works on stock (rooted) MIUI? Thanks!

I flashed it but have yet to test it. Before flashing this I made a phone call and I could barely hear the person on the phone. That's odd because my hearing is amazing.

Thanks for the amazing work!! Nothing try in miui stock?

Hello to all,
Thank you for your work.
Someone knows if on Lineage Rom it works this patch?
Thank you in advance.

Thanks for the mod, it's working on Lineage but the recorded audio is quite low in terms of volume.
If it could be possible to increase it a little bit at least it would be perfect, thanks again!

Hello, i got some questions about this patch:
1. Do i need to root my device to apply it (flash it)?
2. Someone already tried on a Stock ROM with MIUI?
3. Sorry for asking this but, can someone explain thoroughly the process for applying this kind of fixes/patches?
Thank you friends.

Not necessarily, but you have to unlock it in order to have a custom recovery
2. Someone already tried on a Stock ROM with MIUI?
Not that I know of
3. Sorry for asking this but, can someone explain thoroughly the process for applying this kind of fixes/patches?
It's in the OP, as I already said you must have a custom recovery which means unlocked bootloader
Thank you friends.

@danielh1402 could make the previous file available, named lavender-aosp-audio-fix.zip This new file didn't work, but the old one worked. thank you!

Which exact changes were made on the mixer_paths and audio_platform_info files?
I'm trying to fix a similar audio issue on my Mi 9 SE, if you could tell me the changes it may help me a lot.
Thanks.

On Pixel Experience Official this is stoping the video (and sometimes closing the camera) while recording. How do i do to uninstall it?

On Pixel Experience doesn't work, the recorded audio is still awful. And mostly it stops the video recording.
Yesterday I was watching a video recorded with the smartphone and I noticed that the microphones are very sensitive.. maybe they're simply bad adjusted and all we need to do is to lower the gain a little bit.. I don't know. Still hoping for a V2 for this mod.

Tried on Havoc OS. Everything became much worse after flashing this "improvement", nobody could make out what I was saying.
As factory reset did not work and there is no option to uninstall the mod I had to do flashing of a new os with dalvik, cashe and data wiping.
So be aware!

Thanks! This mod work fine in Lineage OS 16 for Redmi Note 6 Pro. The mic volume was very low. Now is great.

Not working in Havoc 3.4. Made the situation worse. No option to uninstall it.
Doing reinstall of entire ROM now.

Joyeuse dialing problem + possible workaround.

Hello, my Joyeuse is having some problem receiving/making cellphone calls. Some of the symptoms are:
- Can not receive nor make calls at all. Outgoing calls end immidiately and incoming calls won't reach.
- Can receive and make calls, but there's no sound on both ends.
- Wifi calls work just fine.
The problem occurs on both custom and stock ROM, and persists after reboot. I have not found the causes but flashing Audio Compability Patch (Magisk) with all "yes" options currently fixes the problem for me. Please let me know this works for you so we would have more information to the problem, thank you.

Had the same problem. Fixed it by updating the voice recorder app to latest version.

same problem here . im on EU rom but it was also an issue with stock rom . theres no updates for the voice recorder app to start with and i do have audio Audio Compability Patch installed since i flashed the rom n the issue is still there
