+ * @file    car_audio_test.c
+ * @brief   Car audio hardware test using the SDK key-tone sine path.
+ *
+ * Notes:
+ * - The SDK sine sample rate is 16 kHz; points is the PCM sample count.
+ * - freq is specified as actual frequency * 512.
+ * - decay=0 keeps amplitude constant for observing DAC/PA end behavior.
+ * - The parameter array has static storage because playback is asynchronous.
