MiUI 10 AAC Support?

[C0nvert]

Hey Guys i finally get my MI 9 and i'm very happy with it.
But one Problem is a real Dealbreaker for me, the AAC Support for my AirPods.

I had before a OnePlus 3 with Oxygen (Oreo Based).
The System auto detects and uses AAC as the default Codec.
But with the MI 9 and MIUI the system only uses SBC wich is a huge quality loss.

Is there a Change to change it back to AAC ?
Root, Magisk ?
Changing in Devolper Settings don't work.

You don't even need to root your phone to get AAC support on MIUI 10, there's an option to turn it on.
It won't automatically turn on due to compatible problem.


Bluetooth->
Paired Device->
" > " button->
Turn the option on->
Done

AAC support in MIUI is tricky. they used some kind of blacklist/whitelist disabling some headphone's AAC functionality.
if you have a headphone in the blacklist, the AAC option in #2 would disappear...
just modify the /system/etc/bluetooth/interop_database.conf add your headphone, or use magisk module to modify it.

I hope you talking about these Steps?

1. Find your Bluetooth Device MAC Adress , something like: XX:XX:XX:XX:XX:XX
2. Write only the first 6 Numbers of it.
3. Disable Bluetooth
4. Go to "/system/etc/bluetooth/interop_database.conf"
5. Search for "[interop_enable_acc_codec]" and insert below this:
6. XX:XX:XX = Address_Based

Can someone maybe upload his interop_database.conf from a MI 9 ?
I need to wait 10 days till i can unlock my Phone.
In the meantime i would go through the interop_database.conf, to see how it is build up.

#   B. Name_Based      D. Vndr_Prdt_Based
#   E. SSR_Max_Lat_Based
##
#   A. Address_Based :  This tag refers to Address based blacklist
#   Input Type       :   Input value should be only 3 to 6 bytes of BD address
#   Format Type      :   Address should be in XX:XX:XX format
#   Examples         :   00:01:03 = Address_Based
###
#   B. Name_Based :   This tag refers to Name based blacklist.
#   Input type    :   Input should be only string and length of the string
#                     should not be more than 248 characters.

####
#   C. Manufacturer_Based :  This tag refers to Manufacturer based blacklist
#   Input type  : Input should be in Hexadecimal Number of Manufacturer
#   Format Type : 2 Bytes Hexadecimal Value
#   Examples    : 0X0023 = Manufacturer_Based
#####
#   D. Vndr_Prdt_Based : This tag refers to vendor and product based blacklist
#   Input type  : Input should be in Hexadecimal value
#   Format Type : 4 bytes hex value( 2bytes of vendor  and 2 bytes of product),
#                 Vendor and product hex values should be separated with delimiter(-).

I hope you talking about these Steps?

1. Find your Bluetooth Device MAC Adress , something like: XX:XX:XX:XX:XX:XX
2. Write only the first 6 Numbers of it.
3. Disable Bluetooth
4. Go to "/system/etc/bluetooth/interop_database.conf"
5. Search for "[interop_enable_acc_codec]" and insert below this:
6. XX:XX:XX = Address_Based

Can someone maybe upload his interop_database.conf from a MI 9 ?
I need to wait 10 days till i can unlock my Phone.
In the meantime i would go through the interop_database.conf, to see how it is build up.

yup. but i just added "Pixel Buds = Name_Based" to add Pixel Buds into the whitelist. maybe without been blacklisted or whitelisted, the AAC option would be there in the bluetooth details.

 

[C0nvert]

So the name of your Bluetooth Speaker are "Pixel Buds" too?
(I don't mean the actual Model Name like "Pixel Buds" or "Airpods"
More the Bluetooth Name you can decide yourself.)

Reviving an old thread...

My headphone supports AAC. But I tried

Adding the MAC address into the whitelist as described above - and found out it is already there in the list

Going to developer options in settings to try and change the Bluetooth attributes there. But the settings won't stick and always reverts back to "system default" when not connected, or "sbc" when connected

So I am stuck with SBC connection. My device is beoplay E6 if that makes a difference.

Any help appreciated !!

Do u have root?
If no, then there's no way till they support AAC on Stable rom

Yes I have root. Please help me !

 

[seemebreakthis]

Can finally see the AAC option. Don't know if I just missed it before or if one of the newer ROMs contains a fix. Anyway it is within the paired devices list, you tap on the right Arrow on the row that shows your device. And the AAC option is on the submenu that opens.

Anyway I now have EEA 10.2.30.0

Did this setting surface after you updated to .30? Did you get .30 over the air? Have you unlocked the bootloader? Many Qs, I know! ?

... Like I mentioned, I am not actually sure if .30 is what fixed the problem. Pretty sure though the AAC option wasn't available way back when I first got my phone. But that was when I had .14 or something like that.

Did several ROM updates along the way, but I wasn't paying attention to this setting until after I updated to .30. and voila, it just appears ! And of course I enabled it right away for my earphones.

Not OTA, I downloaded the ROM and did a manual install.

Yes unlocked and rooted.

It was available before, pretty much since the start for all I can tell. I definitely used it in May

Not for my set of earphones anyway.... That was why I had to ask my questions in this thread back in July.

But now it works.

 

[arrowthefirst]

No AAC for Airpods2 black copy (with original chip inside), tried to torn it on at Dev settings, but it goes back

 

[C0nvert]

On newer MIUI Versions it's working.
If not check blacklist

Hi
I Can not get it to work on not pro with miui.eu 12.3 with Mi Air2 SE...
I try to put 16:81:77 = address_based
Also with name based... But nothing

Any help

 

[Slowking]

Sadly doesn't seem to work on MIUI 12.
The MAC adress of my device (Momentum True Wireless 2) was actually already in the list. I would assume because other Sennheiser headphones share the first three spots of the MAC.
But for good measure I added it name based, via a magisk module and that did not help either.

It's a bit frustrating. My old Bose Soundsport Free connect via AAC no problem, but the MTW2 just won't.

Any idea on how to fix this?

 

[ronnycoleman]

MIUI 12(.5) doesn't even have a /system/etc/bluetooth/interop_database.conf

But the whitelist must be somewhere else. Apple Airpods are using AAC while Samsung Galaxy Buds+ are only allowed SBC although I enabled AAC for them.

Any idea?
