Need to restart my laptop every time to get sound.

Hi Dhana,

Thank you for posting your question in the Microsoft Community Forums.

Based on the information, you are unable to get sound when you switch on the laptop and sound will come back after a restart. Also when the laptop is not used for 15-20min it goes to Sleep mode.

It would be helpful if you could reply to the questions to assist you better.

1. Have you made any recent software or hardware changes on the system?
2. Do you have any external speakers connected?
3. What is the exact model number of the HP laptop?

Let’s try the following steps and check if it helps.

Method 1:

Check to see if the computer speakers are set to be default.

a. Open the classic Control Panel by typing "Control Panel" at the home screen and clicking the "Control Panel" icon.

b. In the Control Panel navigate to "Hardware and Sound" and then click "Sound".

c. On the Playback tab, select the speakers and then click the "Set Default" button.

d. Click or touch "Apply".

Method 2:

You may try running the Audio troubleshooter and check if it helps.

If the issue persists, you may try to uninstall and reinstall the sound drivers and check if it helps.

This problem is intensely annoying. I have found a solution that works for me. It isn't permanent as you have to do it each time the speakers stop, but it is better than restarting all the time.

Go to Device Manager

Right click on Sound video and game controllers

and click "scan for hardware changes"

That works for me.

[SOLVED!]

I was able to solve this problem by switching operating systems (GNU/Linux Distribution). (obviously)

It's a really fun process and quite technologically invigorating to make the big switch from windows to GNU/linux.

Hello, I have same problem.. But I can't set mine to default.. I don't know why, Please Help Me

I have this same problem. When I start my PC I have no sound. I need to restart to get sound.

This problem only started when the PC updated to 8.1 from 8.

I have tried  all the above. As well as new drivers.
