Can't get GIGABYTE DVB-T Hybrid TV Card GT-PTV-TAF-RH to work

I have tried everything to make this card work, but I didn't have any success.
I use Ubuntu Dapper.
Here is what I tried to do to make it work:

sudo modprobe saa7134 card=81 (also tried 2, 78, 3...)

I found on the internet that for my TV tuner card=x have to be 81.

With this I managed to get all required devices to appear in dmesg output:
sudo modprobe saa7134 card=78 tuner=54 gbuffers=32 vbibufs=32 audio_ddep=10 tsbufs=32 oss=1

And here is the output of lspci command:

Now FM radio is working, but signal is very week (in windows it is not). And TV is working too, but without sound.

Can you please tell me how to make it work?

Thanks.
