Hi GainbrainX -

I'm Jerico T., one of the Independent Advisor and a fellow Windows 10 user like you. I understand that you're having some issues right now, let us sort things out.

Please try the troubleshooting methods below and check if any of the methods will fix your concern.

Method 1: Roll-back Audio inputs and outputs driver

1. Open run box by pressing Windows Key + R and type devmgmt.msc then hit enter
2. Locate and expand Audio inputs and outputs
3. Right-click on the driver and select Update driver
4. Select Browse my computer for drivers
5. Select Let me pick from a list of available drivers on my computer
6. Select any older driver from the list and click next
7. Wait for the process to complete, once completed, restart your computer and check if it resolves your issue.

Method 2: Roll-back Sound, video and game controllers driver

1. Open run box by pressing Windows Key + R and type devmgmt.msc then hit enter
2. Locate and expand Sound, video and game controllers
3. Right-click on the driver and select Update driver
4. Select Browse my computer for drivers
5. Select Let me pick from a list of available drivers on my computer
6. Select any older driver from the list and click next
7. Wait for the process to complete, once completed, restart your computer and check if it resolves your issue.

Method 3: System Restore
- System restore is where it will take your computer settings back to an earlier point in time where everything is working fine.

1. Open the run box by pressing Windows Key + R and type rstrui.exe then press enter.
2. System restore windows will open. Normally it will suggest a restore point(Sometimes it doesn't), if it does, select the 2nd option to select more restore points.
3. Select your desired restore point date and time.
4. Once selected, hit next and finish.

Windows will restart itself to start system restore. System restore might take some time to complete and it is very important that system restore must not be interrupted during restore process as it might damaged the operating system. System restore will take at least 20 minutes or more depending on the content of the computer and the changes on the settings that was done prior to the date selected. System restore will also removed application , updates and drivers installed prior to the date selected.

DISCLAIMER:
System Restore is a recovery tool for Windows that allows you to reverse certain kinds of changes made to the operating system. System Restore is used to return important Windows files and settings—like drivers, registry keys, system files, installed programs, and more—back to previous versions and settings. Being said all applications and changes made prior to the date selected will be removed and needs to be re-installed if its needed.

Feel free to reach back if you need any further assistance.

Hope this help. Have a good day.

Thank you.

Hi,

It might seem like it's self-evident, but have you made sure your volume mixer is set up correctly. To open the volume mixer, right-click the volume icon in your taskbar and select volume mixer. Then make sure the audio output is not muted. You might have very well done this already but from ow own experience, I can tell that the problem can just be that simple.

Best of luck!

Thank you for responding. I would be happy if it were something simple. Something I've just overlooked as I have a habit of doing. Yes, I've done those things and many, many others. It's some information regarding the output format has been lost. between the audio output device and my soundcard. Every time I reboot, I get this RunDLL error saying there was a problem starting a module called PYTJDV~1.DLL, which I believe is a Python module. Says it can't find it. This appeared the same time I discovered the music died.

Jerico,

I actually hadn't tried a Sys restore so I did  but no banana.

I don't think the earliest available restore point was early enough. But, man, thanks anyway! I really think this is more exotic or further off the beaten path than a bad driver problem. I've been at this six or eight hours. I have even purchased a new soundcard trying to fix it. Even after uninstalling everything sound driver related, new and old, with some fairly aggressive driver mining software and installing Soundblaster Audigy RX I have had no sign of auditory life from this piece of %%^(*(_(&*546.

Hi GainbrainX -

Thank you for the quick response. Did System Restore works or not? If not, let's try to create a new user profile and check if the same issue will persist.

Create a new user profile
- We will try to create new user profile to check if the issue happens on all windows users on your computer or just isolated on the current profile that you're using.

1. Open the command prompt with elevated access (Administrator Access)
2. Type the below command and hit enter every after command.

net user "account name" /add
(change the "account name" to any name that you preferred)

net localgroup administrators "account name" /add
(change the "account name" with the name that you put in the first command)

3. Close the command prompt and switch to the new user.

Check if the same issue occurs on the new user profile. If in case the issue still persist on the new user profile, perform In-place Repair.

In-Place Repair
- In-place repair/upgrade or repair reinstall is a process of re-installing Windows without touching any of your applications or personal files. In this way if there's any data corruption, damaged system files or missing system files on your computer, this repair will fix or repair them.

To start we need to download an ISO file of Windows 10 and save it to your computer. Please follow the instruction on the link below to create an ISO file

https://support.microsoft.com/en-us/help/402819...

After the ISO is created, follow the instructions on the link below created by PaulSey, Microsoft Agent, on how to perform repair install on your computer.

https://answers.microsoft.com/en-us/windows/for...

This process will take some time to complete so you need to be very patient in waiting until the process completes. Once done , restart your computer and check if the issue is resolved.

Regads,
Jerico T.

That sounds like a good direction. I got to get some sleep now might have to work tonight, but if I don't, I'll start on it this evening.

Thanks. I'll post and let you know what happens.

Hi GainbrainX -

Got it, perform the methods above on your most convenient time. Will wait for the update.

Thank you,
Jerico T.

Jerico,

Back in the saddle.

I have downloaded the updated Windows 10 ISO. Now the burning app say's the ISO is too large for a standard recordable DVD.

The ISO file is 456 GB and the DVDr shows 446 or so GB available. Strange? What about a USB drive?

Oh, the new user profile didn't change anything. nothing but crickets!

Hi GainbrianX,

A System restore option as earlier suggested by Jerico T. will help out if you are able to create a restore point. Kindly use this guide to create a restore point Create a system restore point (microsoft.com) then from here you proceed to carryout system restore Use System Restore (microsoft.com) This should help restore your pc back to audio.

On the second note, as Jerico T. earlier guided you, create a Windows 10 ISO as he has suggested Download Windows 10 (microsoft.com) using at least 8gbUSB Drive. The link will guide on how to create installation media using USB flash drive. Once this is created then make use of the link Jerico T. shared on how to repair your Windows. If that doesn't work;

I will ask that you plug your created Windows 10 USB after a system restart in your pc USB port and run it directly on your PC like you are installing an application software. This should restore your audio back.

Note: I will ask that you backup your personal files on D:Drive  or on your external hard drive.
