Sound problems can be caused by a buggy Windows 10 update, I will be glad to set up a remote session to determine if audio problems can be repaired remotely. Please submit a new help desk ticket and include "sound trouble shooting steps did not solve the audio problem" in the ticket subject line (Brief description of computer problem).
If you prefer to try some troubleshooting first, please view the video in this link and follow the steps while logged into the PC with the Parent account:
This option takes your PC back to an earlier point in time, called a system restore point. Restore points are generated when you install a new app, driver, or Windows update, and when you create a restore point manually. Restoring won’t affect your personal files, but it will remove apps, drivers, and updates installed after the restore point was made.
- Select the Start button, type control panel and then choose it from the list of results.
- Type recovery in the Control Panel search box.
- Select Recovery > Open System Restore > Next.
- Choose the most recent app, driver, or update on the list of results, then select Scan for affected programs. You'll see list of items that will be deleted if you remove this restore point. If you're OK with the deletions, select Next > Finish. Or, if needed, select an earlier restore point before selecting Next > Finish.
Note: If you’re not seeing any restore points, it might be because system protection isn’t turned on. To check, go to the Control Panel, search for Recovery, and then select Recovery > Configure System Restore > Configure and make sure Turn on system protection is selected.
Again, If these steps do not solve audio problems (sometimes cause by a buggy Windows 10 update), we might need to re-install the operating system, programs and Silvies browser settings. Please submit a new help desk ticket and include "sound trouble shooting steps did not solve the audio problem" in the ticket subject line. We will work with your teacher to swap pc's to minimize student downtime.
Thanks for sure,
