Hi Manu,

Thank you for looking into this.

A little bit more info: dmesg reveals:

Is this card being supported? Or did I end up with an unsupported card version?




It's a very much supported device. after loading dvb-bt8xx, you need to load the dst module.

modprobe dst verbose=5 dst_addons=0x20


But dst is already being automatically pulled in when I modprobe dvb-bt8xx, as well as dst-ca. In fact "modprobe dvb-bt8xx" seems to pull in all the necessary drivers at once (bttv, dst, dst-ca and bt8xx).

lsmod output before 'modprobe dvb-bt8xx':

It seems to me that all relevant modules have been pulled in ...... However, dmesg only prints the messages as I have posted above.

I also tried the following sequence:
=> modprobe bttv card=0x71
=> modprobe dst verbose=5 dst_addons=0x20
=> modprobe dvb-bt8xx

But also in this case the result looks exactly the same; also dmesg looks as I listed above.

And what about this "AUDIO function found" message; is that normal ?

Z.
