Laptops sometimes turn on or wake up from sleep without sound

This friend, I've been using the computer for so long with your problem, and it comes and goes, and it usually happens once in a while and then restarts and loads. The main reasons for the high frequency of your phenomenon should be as follows:

First of all, rule out the problem of the sound card and board-level hardware, because it can be used normally, and the sound card is a standard design, and there is almost no possibility of problems;

Drives and systems are a big problem. The driver needs to be talked about,It's not better to update,Precisely,When you start to install the machine,The sound card driver inside the motherboard driver is generally speaking,It's the best and most stable,So,You said that your sound card driver has been reinstalled many times,But it may not be the most matched,This,It is recommended to go to the official webpage to find the driver that matches the current system of the matching model。 Before that, uninstall the old driver.

The system is also a nuisance. Be complete and clean, even if it's a ghost version, look for something that is known to be good, and don't go for novelty and over-simplification and choose unreliable sources. The driver used when reinstalling may not be the most suitable, and it is recommended to install it from the official channel**.

If you do this, there is still a failure, it is a hard injury: when you turn on the computer, the sound card often fails to load, which is a defect in the system, and sleep wake-up is a problem with the hardware firmware for a long time. Design defects can go to the after-sales service to ask about the situation, generally a model of common faults in the after-sales where the technical personnel are very familiar with it, to see if it is the problem of the machine itself.

In the case of a case, ask if there is any good way to solve it.

That's basically the process.

In addition to the hardware, it is the driver problem.

Uninstall the existing audio driver and reinstall the official website driver.

If you don't understand, you can drive the elf instead.

Good luck.

<>1. No sound is a disadvantage because the computer does not bring up the sound card driver when it restarts after hibernation. This is mostly due to the fact that the sound card driver is the operating system of the computer.

The silence is due to the fact that the computer did not bring up the sound card driver when it restarted after hibernation. Most of the reasons for this are that your sound card driver comes with the computer's operating system, and we need to restart the sound card driver.

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;

If the problem still cannot be solved, it is recommended to contact the relevant professional and technical personnel for processing.

The computer hibernate and then start up without sound may be due to the following reasons:

Mute settings: You might have muted or turned down the volume before your computer went to sleep. Please check the volume setting next to the ruler to make sure the volume is set to the appropriate level.

Hardware problems: Sometimes rebooting after hibernation may cause some hardware devices to not work properly. Check that the audio device is properly connected and make sure that the device drivers are up to date.

Hibernation mode settings: Some computers may turn off audio devices while asleep to conserve power. You can try adjusting your computer's power management settings to make sure your audio device works properly after hibernation.

If none of the above solutions resolve the issue, it is recommended that you contact your computer manufacturer or after-sales service center for professional technical support and repair advice.
