I have trawled through so many forums (including this one) in an effort to find a fix for running 5.1 sound under Windows 10. I have tried every one and I can say that none of them make any difference. Stero is the only option.
I note that one forum contributor is frustrated by an apparent lack of ownership of the problem and commitment to finding a solution. I also feel the same.
All I can prove is that the speaker test works every timeon all speakers.
For the record I am running the latest version of Windows 10 Home 64 bit, a Z490 Aorus MB with an I9 processor.
Can someone from Microsoft please advise what is being done about this issue which I am sure cannot be that difficult for a company that designs and manufactures OS used all over the world!
Frustrated is an understatemt!
