The sp887x is on the A761 card, not the A771 which has an MT352 instead.

The 771 doesn't need firmware.

There are other cards which do REQUIRE firmware to be loaded. The
Avermedia 761 is one example. The tuners just don't operate without the
firmware being loaded. Your 771 is not one of these though.
