There is reason you can buy a Echo Layla 24 on eBay for 50 dollars.
There's also a reason Echo audio has decided not support that card anymore.
"
We do not currently support Windows 10 and have no plans to update our
drivers."
I don't know of anyway to bypass this issue even if you could get it to work but caution.. If you pay for parts and shipping then find out its not compatible, well your going to be upset.
See its not just about the windows drivers with the layla24, some chipsets have also been an issue on certain motherboards.
On those older boards the PCI slots used a native chipset. As in they had their own dedicated chipset handling the data to and from the CPU. .
newer motherboards don't have the same type of PCI standard. They still have PCI slots but now they are what is called "Bridged"
Which means your data is taking a detour to a chipset intended to process data from the newer PCI slots.
