When you click the Download tab on that page, there
are no drivers.
*However*, there is a blue colored "Request Driver" button.
You give them your email address, they send you the driver
as an attachment or whatever.
This is intended to reduce download bandwidth. So only
customers will pester them.

Chipset: VIA VT1723, VT1618; ASMedia ASM1083
The ASMedia chip description reads like this.
ASMedia Technology Inc. ASM1083/1085 PCIe to PCI Bridge
That means, it converts the PCI bus interface on the Envy24DT
into PCI Express signals your newer motherboard can use.
You should not need a driver for the ASM1083. So that's
one item out of the way.
This also means, that when searching for a driver,
you can look for a VT1723 driver on the VIA site.
No guarantees how well this will work, and you'd need
to use the PNP information visible on the Device Manager
properties, to get some idea whether the driver is
a good match or not.
Note - this is an annoying web page. Use a modern browser.
So what you search for here, is

Windows 7 <---- set this so *some* driver shows up...

The link I got to the driver is this, but by the time
you read this, it's entirely possible the link will be
dead. This could be a dynamic, one-time link.

The driver is 9.1MB.
You look in an INF file in the drivers folder, for lines of this nature.
VEN_1412&DEV_1724&SUBSYS_
Now, my problem is, I don't know the SUBSYS value
for "Syba", so I cannot verify that is the
correct or workable driver. That driver works
with many different brands of cards. The SUBSYS field
might help the card determine what the CODEC type
is, which is past the Envy24.
And by not telling us the OS you're using,
you made this harder than it needed to be.

As Philo says, you can also ask the Device Manager
driver update thing, to search the microsoft site
for the necessary file. The difference when doing
it this way, is you may not get the "fancy" control
panel for the card, and may get just enough driver
to get 2 channel sound or whatever. I prefer to track
down a "real" driver if I can get one.
And no, you don't necessarily turn to driver_of_the_week
site or some_random_webpage to get your driver. You
could get malware that way. Only a few of those sites
have really good reputations. Notice that I am trying
to trace the lineage of the card, to find you
a driver.
And after all these years, I *still* cannot get
a SUBSYS list. PCIdatabase lists VEN and DEV, but
no SUBSYS. The damn things are registered somewhere,
and each manufacturer has to apply for a unique code.
