When playing music via CarPlay, there is no sound from the car stereo. How can this be solved?

1. Confirm whether the head unit's radio channel is occupied by the phone or an FM broadcast, etc.

2. Reset the head unit system

3. Long press the product's reset button for 10s until the white light turns on, or connect to the product's WiFi, enter the password 88888888, open the phone browser and enter 192.168.1.101 to access the backend management page, then click Restore Factory Settings

4. On the backend management page, find the audio stream mode and manually select mode 1, then wait for the device to restart and test. If the problem still exists, please switch to mode2 and test
