Forcing LDAC Standard quality on Ubuntu involves editing a configuration file and potentially restarting services. Here's how to do it: 1. Check your Ubuntu version: Knowing your version is crucial as the configuration file location might differ. Open a terminal and type:

``` lsb_release -a ```

This will display information including the version number. 2. Edit the configuration file: There are two main scenarios depending on your Ubuntu version: For Ubuntu 17.04 and older: The configuration file might be named audio.conf. Use the following command to edit it with sudo privileges (replace nano with your preferred text editor if needed):

``` sudo nano /etc/bluetooth/audio.conf ```

If the file doesn't exist, you can create it. For Ubuntu 18.04 and newer (including PipeWire): The configuration file is likely named main.conf. Use the following command to edit it:

``` sudo nano /etc/bluetooth/main.conf ```

3. Add the configuration line: At the end of the file, add the following line:

``` # Force LDAC standard quality bluez5.a2dp.ldac.quality = sq ```

4. Explanation of the line: bluez5: refers to the Bluetooth version (might differ slightly based on your version). a2dp.ldac.quality: specifies LDAC codec configuration for A2DP profile. sq: sets the quality to “Standard Quality”. 5. Save and restart: Save the changes in your text editor. Restart the Bluetooth service:

``` sudo systemctl restart bluetooth ```

Additional notes: This method forces LDAC regardless of device support. Compatibility issues might arise. LDAC Standard quality uses less bandwidth than High Quality but may have a slight audio quality difference. Consider using a Bluetooth management tool like Blueman ([blueman package]) for a more graphical interface to manage codecs (although forcing might not be available through the UI). Remember, forcing a specific codec can lead to unexpected behavior depending on your device and Bluetooth version. It's always best to check your device's manual or manufacturer's website for supported codecs.
