I have the exact same card (purchased it today by the Aldi in the NL).

I'm running Linux 2.6.0-test6-mm4, which comes with version 0.2.8 of the
saa7134 driver. When I load the saa7134 driver without parameters, I get
no image in xawtv, so I experimented a bit with different card=X
options. I found that card=9 works pretty well, with both overlay and
grabdisplay. I can actually watch a bit of TV.

However, none of the card options gives me sound. I get either complete
silence or static. Sometimes, on some channels, I can hear - very very
faintly - the TV through the static.

When I load the saa7134 module with card=9, I get the following kernel
messages:

(URLs removed because of length)
The last line will repeat itself, sometimes with alternating MHz values;
I've seen 5.000, 5.500, 6.000 and 6.500 iirca. My speakers are connected
directly to the audio-output of the TV card.

Someone on http://www.linux-community.de/Neues/story?storyid=8736 seems
to have the same problem. Someone else suggests using card=5, but that
doesn't help for me.

I also tried to saa7134-20031009 snapshot from
http://bytesex.org/saa7134/, but that yielded the same results.

This is what lspci -vvv has to say about the card:

The output is identical with or without drivers loaded.

I have made a couple of pictures (about 1.3MB's worth):

Well, I guess it's a TV card :P
