Windows 10: Windows 10 application audio silenced on return from sleep

I have established that Windows 10 (Home 1809) suppresses application audio on return from sleep until the screen is unlocked.


This is reproduced as follows:

• Start music playing on your favourite media player - Sound comes out of speakers
• Press the sleep key or do Right Click Windows Icon, Shutdown, Sleep - Sound stops and machine sleeps
• Hit a key to wake machine up - Machine returns in lock screen with no sound
• Enter password/pin to unlock - Sound resumes

This is not a driver issue, I have reproduced it on several systems including a vanilla surface pro 4


The problem is not that the audio is simply muted. When the system is on the lock screen and silent . The mute key is operational and toggles the mute state on the volume popup that appears over the lock screen, but without restoring sound.


I have the impression, although I cannot substantiate this, that this behaviour is recent and did not occur prior to the Creator or a more recent update.


It may be that this is intended behaviour but it impacts what I am trying to achieve with a program that plays music on a headless PC with remote control over the network. Possibly I could not lock the screen on return from sleep but that presents security issues.


I would like to either disable this silencing of the output after sleep or have a programmatic way of restoring the sound when my application (coded in c++) resumes after sleep. Any pointers to audio flags or structures that might be involved would be greatly appreciated.


Many thanks for reading this far

The Ultimate Realtek HD Audio Driver Mod for Windows 10

Hi all,

I have an issue to my windows 10 HTPC / Radeon rx 560 HDMI audio out to a Denon x2300w. Using the stock windows audio drivers I can't get more than 2.0 stereo. Surround sound content just results in silence when passed as bitstream.

It was suggested that I try this Dolby driver, but I see that it has not been updated in a while. I am curious if the user's here think this is a worthwhile solution.

Best,
Rob

Everyone that post ids, need just do these steps and you will be good. I kinda tired of keep on uploading the inf. file

1.Go Open up device manager
2. Go under sound,video, and game controllers
3. Find Realtek High Definition Audio
4. Right click and hit update driver
5. Browse my computer for driver software
6. Let me pick from a list of available drivers on my computer
7. Click Have Disk and hit browse
8. Click on the Realtek HD Audio mod folder and look for win64
9. Click on the HDXRT4 and click ok,
10. Click Next and Yes
additional if you want dts audio and others, install it now before next step.
After it is done, restart the PC

You should be good then and also make sure before doing these steps that you have driver enforcement disabled.
