		* Check if dual mode audio is enabled. This is set via the system property
		* persist.bluetooth.enable_dual_mode_audio.
		* <p>
		* When set to {@code false}, we will not connect A2DP and HFP on a dual mode (BR/EDR + BLE)
		* device. We will only attempt to use BLE Audio in this scenario.
		* <p>
		* When set to {@code true}, we will connect all the supported audio profiles
		* (A2DP, HFP, and LE Audio) at the same time. In this state, we will respect calls to
		* profile-specific APIs (e.g. if a SCO API is invoked, we will route audio over HFP). If no
		* profile-specific API is invoked to route audio (e.g. Telecom routed phone calls, media,
		* game audio, etc.), then audio will be routed in accordance with the preferred audio profiles
		* for the remote device. You can get the preferred audio profiles for a remote device by
		* calling {@link BluetoothAdapter#getPreferredAudioProfiles(BluetoothDevice)}.
