    LDAC is an audio coding technology developed by Sony. LDAC support up to 990kbps bandwidth and maximum bit depth and frequency of 96kHz/24bit. LDAC is supported by Sony Headsets like Sony WH-1000XM3, WH-XB900N/B, Sony Walkman, Sony Active Speakers and Sony Home Theaters systems.

    LDAC vs SBC (Source: https://www.sony.net/Products/LDAC/)
    In Linux distributions, Bluetooth SIG’s SBC and LC3 codecs are enabled out of the box. However to enable AAC, aptX-HD, LDAC separate propriety codec is needed be installed. From Android 8 Oreo, LDAC became a part of Android Open Source Project¹ . Then bluez-alsa and pulseaudio-modules-bt² packaged it. However due to the possible licensing restrictions, LDAC module should be installed from RPM Fusion repository as follows.
    Step 1: Install pulseaudio-module-bluetooth-freeworld
    # dnf install pulseaudio-module-bluetooth-freeworld — allowerasing
    Then the codec and libraries will be installed in Fedora overwriting the existing pulseaudio-module-bluetooth. It is more likely following package will be installed/removed.
    Installing: pulseaudio-module-bluetooth-freeworld ( From rpmfusion-free repository)
    Installing: libldac ( From Fedora repository)
    Removing: pulseaudio-module-bluetooth ( Installed from initial system installation)
    Step 2: Then have a system reboot or do a service restart to Bluetooth service.
    # systemctl restart bluetooth
    Then it should be able to see the LDAC configuration in Sound Settings.

    Output Device Configuration of LDAC
    Step 3: Install Gnome Shell Extension “Bluetooth quick connect” for fast device switching from URL https://extensions.gnome.org/extension/1401/bluetooth-quick-connect/

    蓝牙的上传速率40K/s也就是320Kbps,3分钟能传输7MB,一首3分钟的音乐无损glac格式20MB,HQ高品质8MB,总体算下来还好吧

    I succesfully implemented LDAC and AptX, AptX HD codecs in Deepin 20.9 using this script

    It is designed to Debian so before starting the script we need to make small change in /etc/os-release

    temporary changing

    VERSION_CODENAME="apricot"
    ID=Deepin

    into

    VERSION_CODENAME="buster"
    ID=Debian

    using command sudo nano /etc/os-release.

    This allows to execute script without errors and we can enjoy high quality bluetooth stream in Deepin.

    After succesfull execution of script reverse changes made in os-release and check if /etc/apt/sources.list doesnt contain any debian buster lines if so then put # or delete
