What can I do if the audio/video cannot play properly on the TV via the USB drive?

If the TV cannot play the audio from the USB drive successfully, please follow the below methods to do the troubleshooting:

1. Check whether the TV supports playing the format of the audio/video.
2. Change another video/audio that plays on the TV.
