Windows 10: sound disappears or does not resume when unlocking device or waking up from sleep mode or...

I have seen this issue on edge, chrome, and firefox. current device is a surface pro 3 4gb ram 128 gb running the latest version of windows 10 (I am not in beta or insider for anything). for some unknown reason, the sound has disappeared when trying to resume a video on youtube. every time this happens I have to exit fullscreen and pause the video and wait for the audio speaker icon on top of the tab to fully go away and then resume. very rarely the sound completely disappears to the point that I have to restart my device. this has been going on for nearly a year and I have no clue what is causing this very annoying and frustrating issue. I have done the audio troubleshooter and it does not detect anything. any help? is my sound driver faulty? is the audio card dying?

also the audio drivers are up to date and disabling and reenabling them does not help

Windows 10 - Problem waking up from sleep mode

This worked for me on a Lenovo Horizon2 27 all-in-one PC that was able to sleep manually but could not be wakened once sleeping after upgrading to Windows 10 Home.

I ran the powercfg /energy and examined the report as GoWMike describes. It showed no driver errors but suggested that there is a problem with the system's "High Performance" power setting that may prevent normal waking from manually induced sleep.

I used powercfg /list to show available modes, copied the GUID for Balanced mode, and then used this with the powercfg /activate command to change the plan.

I also used powercfg /devicequery wake_from_any

to get a list of device names for components capable of waking the system from sleep, and then I used

powercfg /deviceenablewake <devicename>

to make certain that the touchscreen and power button are armed to wake the machine.

After restarting, sleep and wake then functioned properly again.

 

Waking up from sleep mode

Hi Phil,

If you are unable to get out of Sleep mode, it could mean that the BIOS installed reduces the power to which your input device is connected, i.e. mouse or keyboard. For us to properly assist you in getting out of Sleep mode, kindly respond to the questions
below:

• Can you explain further what you are experiencing? Were you able to get to the lock screen after waking from Sleep mode?
• Are you using a laptop or a desktop computer?
• When did the issue start to occur? Did it happen after installing an update, an app, or a driver?
• What troubleshooting steps have you done so far? This is for us to know and to avoid any duplication of efforts on your end.

We look forward to your response.
