There will be sound on the stereo, and there will be no sound for a while

There may be several reasons why the speaker will have sound and no sound for a while:

1. Poor contact of external wiring: You need to check the connection of the speaker to make sure that all the wiring is connected.

2. Internal power amplifier circuit problems: for example, the main volume potentiometer has a rustling sound when it rotates, or the sound is loud and small, whether the interfaces of the circuit board are in good contact, shake the connecting wires and circuit boards, and see if it is caused by poor contact.

3. Rectifier power supply problem: If the sound only appears when the rectifier is turned on, it may be that the current of the rectifier power supply is too small, resulting in the sound blockage caused by insufficient driving force of the power amplifier part, and it is necessary to check whether the output voltage of the rectifier power supply is too low.

4. Audio file problem: There is a problem with the audio played, and the frequency is not enough.

5. Driver problem: You can check whether there is a device with a question mark in the device manager, if there is, the driver is missing, and you can reinstall the driver.

6. Audio Setup Issues: You can go to the Control Panel to find "Sound & Multimedia" and check if the playback device in the audio device is selected correctly.

7. Hardware problem: If none of the above methods can solve the problem, it may be a hardware problem, such as a damaged bass potentiometer of the speaker.

It's important to note that Question 1 and Question 2 can exist at the same time, so you need to check carefully when troubleshooting issues. If the problem persists, it is advisable to replace the audio test or seek after-sales service.
