Question 1: There is no sound and the frequency spectrum is beating

You can connect both ends to the headphone jack, or you can replace it for better shielding. line;2. Check that both ends of the 3.5 audio cable are plugged into the headphone jack, and they are inserted to the end. Rotate to rule out bad contact; (Many new customers have encountered that the audio cable is not inserted to the end, and there is a distance of 1-2 mm. The picture is inserted in the end)3. If you turn on voice control, there will be tiny sounds around, the spectrum will be detected, and the automatic gain of the spectrum will be enlarged and displayed. This is a normal phenomenon;4. It is normal for the frequency spectrum to jump when the finger touches the microphone and surrounding lines of the control card;5. If your audio equipment has noise floor, although there is no song, spectrum automatic gain will amplify and display the noise floor, how to judge whether the spectrum is normal: turn off the voice control switch, and unplug the audio cable of the control card, wait a few seconds, if The frequency spectrum does not jump to prove that the frequency spectrum is normal, you can also change other audio equipment to test.
Problem two: dual-screen display, one screen displays normally, there is a line in the middle of the other screen
Solution:This is because the control card is set to the single-screen mode, and the empty-color dial switch 2 can be pushed to the dual-screen position.
