Making it Work

This card is not supported. Further work is blocked on development of the SAA716x driver.

Firmware

This card may require firmware. There is no reason to assume that standard firmwares currently available for the tuners and demodulators will not work.

Drivers

Users wanting to attempt can try the experimental drivers for the SAA716x.

Sample Kernel Output

Provide the relevant portion of dmesg here. For example:

# dmesg

Remote Control Support

The bundled USB ir device and remote work as a /dev/input keyboard device. Several of the mappings are not usable in linux.
