Computer hibernation is a power-saving mode in which the computer shuts down branches and hardware devices to save energy. If the computer does not fully recover during the hibernation process, it can cause some devices to behave abnormally, such as a sound card.

When you wake it up from your computer's hibernation, the sound card restarts, but sometimes the sound card may not recover correctly. This may cause the program or operating system to not be able to use the sound card for audio output normally, resulting in a "no sound" problem.

To solve this problem, you can try the following steps:

1.Replug and unplug related equipment such as headphones and speakers to ensure they are installed and functioning properly;

2.Open the Control Panel, select"Hardware and sound"with"Audio equipment"and see if the current default audio device is correct;

3.update or reinstall the sound card driver;
