Как включить поддержку LDAC для PC на наушниках HUAWEI FreeBuds Pro 3?

I found a simple (well, kinda) way to enable LDAC for Huawei earbuds on devices that lack the sound quality option in AI Life. It worked for my Pixel 8 Pro and probably should work on any device that supports LDAC.

What should you do:

Install SSP Terminal on your device. I suggest Serial Bluetooth Terminal.

Pair and connect your earbuds to your device.

Open Serial Bluetooth Terminal, choose Devices in the hamburger menu.

Tap on your earbuds from Bluetooth Classic list. After that you should see a terminal window saying Connecting to <your erabuds>... Connected (see screenshot below). If you're unable to connect to your earbuds' terminal, make sure they are connected to your device in Bluetooth settings.

Long press on M1 to edit macro. In Edit Macro window do the following:

Set Edit mode to HEX.

Input 5A 00 06 00 2B A2 01 01 01 B5 EF to Value. That's what AI Life sends to earbuds to prioritize sound quality (e.g. to enable LDAC).

Save the macro by tapping on the tick in the top right corner.

Tap the M1 button. You must see something like that (note two green messages in the end — that's a sign of success):

After that, LDAC must be enabled for your device. To ensure that, you may go to Developer options of your device and scroll down to Bluetooth Audio Codec, it should say LDAC.

Worth noting that on Samsung devices you have to explicitly enable LDAC in your earbuds' pairing options in Bluetooth settings.

If everything went fine, you may safely delete SSP Terminal from your device. Depending on your earbuds's model you may have to repeat described steps on every paired device.

Hope this will help!

It's important to say that all credits should go to OpenFreebuds developers, since I used their implementation of Huawei's proprietary protocol to build magic message from step 5.2.
