The sound card control panel was reset. Open the audio manager, click the jack setting key on the right, and then you can see that the jack detection on the front panel is disabled. Check it and press the OK key.
Check whether the sound card of the manager is disabled. Open the computer settings key, and then click the management key to enter the device manager to check whether the sound card in the audio, video and game controllers is disabled. If it is disabled, the "Enable" option will appear, just click Enable.
The sound card driver was not successfully installed. If the sound card driver is installed, it is still unsuccessful. Generally speaking, there are two situations. One is that the sound card driver is normal, but names such as Realtek "via" IDT will appear in the device manager. If there is no brand name with these prefixes, it is likely that the driver is not installed successfully, and the other is that the exclamation point of the common sound card driver is not installed successfully.
