Control Panel Audio doesn't open ; No Audio ; USB Bootdisk plays audio
HI everyone,
I'v been sitting with a issue of no sound for 2 days now and am determined to fix it Vs reinstalling & not learning how to fix this issue. Sorry for such a long post, but the devil is in the details.
The issue is *NOT* driver / hardware based {Audio works 100% when booting off of Gandalfs W10 ISO from a USB} . The issue is some corruption within Windows , below the driver level {multiple driver reinstalls} , and possible on or below the service layer.
Also Nothing related to audio in the Control Panel opens {error= "Windows Audio Service is not enable}. Right clicking the Audio Icon in the task bar shows no devices to playback or record audio on.
Before issue started:
Creators update installed. Everything was fine for a few days afterwards. Just before the issue started my Explorer.exe suddenly stopped working, & I couldn’t manually relaunch it using Task Manager > Run New Task > Explorer.exe. I had to manually reboot and after tha,t the audio stopped working.
Iv tried the following (pretty much in order):
- System Restore – No point’s available, besides 2 created AFTER the issue happened. Murphy’s law :P
1)New Os Profile.
2)Enabling built-in Adminster profile.
3)Uninstalling Realtek driver + nVidia drivers , using CCLeaner to remove any remanence from the Reg and then letting the OS reinstall the Realtek drivers.
4)Installing latest Realtek drivers from their site, which I see are also listed on TenForums.
5)Updating Realtek drivers using the Cab-files which I see you guys also suggested.
6)Running SFC / Scannow - No errors found (tested inside OS & from W10 USB).
7)Dism /scanhealth ; Dism /checkhealth ; Dism /restorehealth (tested inside OS & from W10 USB). All return "No corruption found".
8)Win Audio Troubleshooter detects the Audio Service is *not* running, but it (troubleshooter) runs indefinably OR says it can't start the service).
8.1)I'v tried restarting the services "WindowsAudio" & "WindowsAudioEntpointBuilder" {Both set to Automatic} under Services.msc but these fail to start.
8.2)I’v set both these services to use the “Local” Account but no luck, so I set them back to the ”NETWORK SERVICE” account.
8.3) I replaced \system32\audiosrv.dll & AudioEndPointBuilder.dll with the DLL's from the mounted Win10 .WIM \System32\ folder.
I also replaced all other \System32\ AUDIO related DLL's (ones with audio in the name :P :P ; Please let me know if you know of others worth replacing).
8.3.1) I tried running sfc /scan (inside OS) after that, but it got stuck on 75% for > 30min (Samsung 960 NVME) and showed 0% CPU & RAM use which was constant for atleast 10min.
8.3.2) I tried re-registering audiosrv.dll & AudioEndPointBuilder.dll using regsvr32 but I got error “entry-point DllRegisterServer was not found. Make sure \audiosvr.dll is a valid DLL or OCX file”.
9) ALL Files in System32\Config\Regback = 0MB . This explains why I don’t have any older registry points.
I'v got some older reg files from Dec 2017, which I'd like to expend and find+merge "the Audio section of the Control Panel" into where ever they must go, but I'v not found info on which keys to export.
10) Under Event Viewer > Windows Logs > Application I have plenty of:

Both point towards SVCHOST.EXE (not replaced) & AudioEndpointBuilder (replaced) so I’m a bit at a loss.
What Im going to try so long is:
1)Replace the new AudioEndpointBuilder.dll with the AudioEndpointBuilder.dll.old I saved.
2)Make Windows think its Win 10 Home, so I can ‘upgrade’ to Windows 10 Pro.
