Never did get it to work in 10 so I put together a different PC with 7 and found some drivers, not from Leadtek, that work, but make the tuner appear to be for some other non-US region. If there are initialization problems, they occur outside of the btaudio driver. The functions it supports are all integrated into the BT87x; all that is required is that the analog audio from the tuner is connected to the analog audio in on the chip, which in most cases it will be. Petr Vandrovec describes a case where a bt card fails to work with the btaudio driver unless it is first initialized by a Win98 driver:. Digital audio won’t work in the majority of cases because there is no external digital audio source to drive it. It only does a few things, roughly something like:.

On the datasheet, the relevant pins are 94, 98, and DScaler can access the input, despite the installed driver not working. Forum Windows 10 Forums Drivers and Hardware.

Windows 10 Pro CPU: While a digital signal processor such as bt88 MSP34xx is required for btaudio’s digital mode, any bt87x card has the required hardware to work with btaudio’s analog mode.
