For this to work, you'll need to set xc3028 parameters. This device needs a
reset during firmware load. This is done via xc3028_callback. To reset, you
need to turn some GPIO values, and then, return they back to their original
values. The GPIO's are device dependent. So, you'll need to check with some
software like Dscaler's regspy.exe what pins are changed during reset.

Also, there are two ways for audio to work with xc3028/2028: MTS mode and
non-mts. You'll need to test both ways.

A final notice: most current devices work fine with firmware v2.7. However, a
few devices only work if you use an older firmware version.

Could you please send us the logs with i2c_scan=1?

Please, use the latest version of v4l-dvb, since I did some fixes for cx88 and
saa7134 there recently.

Cheers,
Mauro
