Windows 10: Sound turns off when computer wakes up or starts

All of a sudden, every time I start up my computer or it wakes up from sleep mode, the sound is turned off. I didn't change any settings. This just started yesterday.

computer wake-up after sleep

Did all the steps exactly as shown above and "Allow this device to wake the computer" was already selected.

I think you might have miss-understood the problem. It appears that the computer is waking up, but it doesn't re-connect to my display. I have to turn off the display and turn it back on to get my display to to re-connect. This was not a problem prior to
the last Win 10 upgrade.

 

Computer Randomly Turns on From Sleep

I only saw this thread now, otherwise I would have suggested this sooner.
I had that same problem you are having, my computer was waking-up from S3 and the culprit was my X7 mouse.
powercfg -lastwake also listed the HID keyboard device which was an extension of the mouse.
Besides going in device manager and setting everything to not being able to wake-up the computer from S3, I also did this to the power profiles:



Worked for me.

 

waking up my computer

Hi Virginia,

For us to properly isolate the issue in waking up your computer, we would like to know the following:

• What is the make and model of your computer?
• Were there any changes made on your computer prior to the issue (e.g., updates, software installation)?
• Aside from a hard shut down, to make sure that we have not missed on anything, what other troubleshooting steps have you done so far?

In the meantime, we suggest that you check if the wake on keyboard option is enabled. To check this, open
Device Manager > Keyboards > HID Keyboard Device >
Power Management, and then disable the Allow this device to wake the computer feature (standard value).

We would appreciate it if you could get back to us and provide us your feedback.
