Sony WALKMAN MZ-G750PC Operating Instructions Manual page 91

Fix: A lot of the large branded computer manufacturers ship their
systems with a cutdown OEM version of Windows that does not
always include all the USB audio components.
Because this is specific to each manufacturer, you will need to
contact the one who built your system and ask them to send you a
USB audio upgrade to bring your version of Windows up to the same
standard as the retail version. The Digital PCLink does not need any
special device drivers, using only the following generic Windows
ones that are usually stored in the listed directories for each USB
component:
C:\wintinAusb.inf - driver location for USB Composite Device
C:\win\inf%iddev.inf - driver location for USB Human Interface
Device
C:\win\inf\wdma-usb.inf - driver location for USB Audio Device
These drivers are all that is needed to operate the Digital PCLink.
2 My Digital PCLink looked to install fine, but I cannot
select it as preferred device
Problem: Your Digital PCLink went through most of the driver
install or all of the driver installation fine, but now when you try to
select it in the Playback section of the Mu/tirr&ia control panel,
there does not appear to be any option for USB audio device.
