For the people interested; AVIRA is not giving a false positive for the new version (no clue why it did previously):

Hey guys, sorry for resurrecting this post but I had the same issue I wanted to give an alternative to MrQ's application, as this is a really simple script you can run, the only requirement is devcon.exe which is easily obtainable.

First off, MS have removed the option to download devcon.exe on it's own, now it requires you to download a whole kit, but there is a way around this, I use elgato software to record gameplay and found that the soundcapture software requires devcon.exe, so if you have elgato software installed or if you decide to install it to get the devcon.exe, you just need to go to "C:\Program Files\Elgato\SoundCapture\Driver"

Just copy devcon.exe to your desktop, preferably in a folder, next you need the script, below I've provided two options,

Option 1: A vbscript which hides the command prompt window and runs the command as admin (which is required), so when you double click it and approve it, it will disable/enable your audio within seconds thus fixing the problem.

Option 2: Is a basic batch file with just the command in it, when running this you will have to manually RunAsAdmin, and it will popup on your screen for a moment while it runs.

Just make sure that the vbscript or the batch script is saved in the same folder/location as the devcon.exe file in order for it to work.

Copy the following to notepad and save it as AudioFix.vbs in the same location as devcon.exe
Code: Dim wShell Dim oShell Dim strArg Set wShell = WScript.CreateObject ("WScript.Shell") Set oShell = CreateObject("Shell.Application") strArg = "for /f ""tokens=*"" %A IN ('devcon.exe find *Audio* ^| findstr ""Audio""') DO for /f ""tokens=1 delims=:"" %B IN (""%A"") DO for /f ""tokens=1,2,3 delims=\"" %C IN (""%B"") DO devcon.exe disable ""%C\%D"" & devcon.exe enable ""%C\%D"" " oShell.ShellExecute "cmd.exe", "/C CD "& wShell.CurrentDirectory & " & " & strArg, "", "runas", 1 Set wShell = Nothing' Set oShell = Nothing'[/quote] Or copy the following to notepad and save it as AudioFix.bat in the same location as devcon.exe
Code: CD %~dp0 for /f "tokens=*" %%A IN ('devcon.exe find *Audio* ^| findstr "Audio"') DO for /f "tokens=1 delims=:" %%B IN ("%%A") DO for /f "tokens=1,2,3 delims=\" %%C IN ("%%B") DO devcon.exe disable "%%C\%%D" & devcon.exe enable "%%C\%%D"[/quote] I hope this helps everyone with this audio issue, I personally use this without issues, but if you have any problems PM me.

 

Wow!!!
Many thkx for this fix!!!
I also have this problem with my Intel 530 audio via HDMI !!! When I get back from standby, not always have sound. Most of the time I have to restart or wait 10 seconds after resume to turn my monitor in order to have sound back, but not always this last fix works.
But now I can easily have hdmi sound again
Thkx again!!!

 

Just wanted to say I'm another person with the same problem(HP pc hooked up to 55" Vizeo 4K tv)that when I bring it out of sleep mode(it just started this about a couple of months ago) it sometimes will have a red x across the volume control in the notification area and no sound......And this only happens intermittantly.

I will try some of your fixes and hope for the best!

 

I have a intel nuc with the same issue. I tried this and replaced text with AV Receiver (Intel(R) Display Audio) but it did not seem to work here, any advice?

 

wow..great MrQ I added the correct string,Intel(R) Display Audio, and it was back in a second. I have tried many reset tips but this worked.
