+Cubie A5E 主板**未配备 3.5mm 耳机接口**。系统默认音频输出优先级为「蓝牙音频 > 耳机 > HDMI 音频」，其中「耳机」选项将在连接 USB 耳机或通过 40 Pin GPIO 接口连接外部 USB 声卡时生效。
+
+如需通过 40 Pin GPIO 接口使用数字音频，可使用 I2S2 接口（需外接 DAC 芯片转换为模拟音频）。

+
+:::note Cubie A5E Audio Interface Note
+The Cubie A5E board **does not have a 3.5mm headphone jack**. The default audio output priority listed as "Bluetooth Audio > Headphones > HDMI Audio" means the "Headphones" entry will appear when a USB headphone or external USB audio card connected via the 40 Pin GPIO is detected.
+
+To use digital audio via the 40 Pin GPIO interface, you can use the I2S2 interface (requires an external DAC chip to convert to analog audio).
