To summarize the above comments and show how to proceed in analyzing such problems:
Before formatting the disk one should always take some precautions,
like taking an image of the system disk and at least a backup of all the drivers. Unfortunately, this was not done here.
There are only two possibilities in this case to find good drivers :
- Let Windows assign its own drivers
- Download drivers from the manufacturer's support website.
Both of these were done, but did not solve the problem.
Sometimes older drivers for the device work better then the latest version,
when the problem was only recently introduced, so are worth searching.
But there were none to be found for the Asus Xonar AE.
The only tool to resolve audio problems within Windows itself
is running the Troubleshooting tool for "Playing audio".
That did not help either.
I pointed to two posts that contain many workarounds for audio problem
that could help:
Unfortunately, the poster tried all the suggestions, but none of them helped.
Basically, we have exhausted here all the easy solutions.
There are now only these possible avenues for a solution:
- Reset or Refresh Windows back to the original manufacturer's version
to return the original drivers.
If Windows 10 was an upgrade, this may restore the previous Windows version.
This option is not always available, depending on
the chosen upgrade path and whether the entire disk was formatted
or only the Windows partition.
- Survey the Asus support website for future driver versions
- Contact Asus Support for advice on fixing the problem
- Ask Asus Support for an installation disk for Windows 10 for this computer model (may require a small payment).
- Use another sound card for which Windows has a good driver.
I wish to stress to every reader that doing a clean install of Windows is
a very dangerous operation. Proper backup is absolutely necessary
and a restore option should always be set up, because the new
installation may have problems whose solutions only exist
in the installation that was wiped out.
Such problems may be very hard to solve even for experienced users.
Thanks for the recap Harrymc :) And for the help ! I now use, temporarilly, my monitor speakers via HDMI, and it works, and I'll reach my retailer to get a refund :/ – HeavyNounours – 2018-03-20T21:26:50.097
