Card subsystem is identified as 4e42:4307, which I didn't find in the list of supported cards by v4l. However, tHis forum (http://lists.zerezo.com/video4linux/msg15910.html) reports the card to be working (except for radio) with card=60 and audio_clock_override=0x00187de7 parameters to the module.

my, this is close to three years back!

The only reports we ever had were from Paul and he tried across
different cards and it was never finished. It has no radio and only one
single RF in connector.

BTW, do you know about an extra fan for cooling the tuner?
Likely not anymore on a tda8275ac1 and mini PCI.

That is a nightmare of wasting time. Given that all card entries were
still volatile that time, especially for gpio settings, I would to have
to dig out on what exactly version Paul was and compare it to an Ubuntu
2.6.18-11. Ugh!

On what you really are? They do down port several kernel versions
without problems, but card=109 is a few away from vanilla 2.6.18.

To add more, AFAIK, in Spain you use NICAM-BG for stereo sound and
around that 2.6.18 it might have been broken in favor of NICAM-DK.

The module names even did changed a lot, can't even tell the right debug
options off hand any more. With saa7134 audio_debug=1 you should at
least see, if it fails to detect NICAM-BG and hangs on other audio.

Start simple, say xawtv/tvtime and
sox -c 2 -s -w -r 32000 -t ossdsp /dev/dsp1 -t ossdsp -w -r 32000 /dev/dsp

I have also tried using the parameter audio_clock_override=0x00187de7 when loading the module with the different card values, but the result is the same.

Paul later reported that it works for the Philips Tiger S card=109 and
it has for sure a LNA config type 2. That explained the better image at
that time already with clear symptoms of missing LNA support previously.

It is difficult on 2.6.18.
You must upgrade to current mercurial v4l-dvb.

Currently it does not even compile on a 2.6.30.

make[3]: *** [/mercurial/hg-head/v4l-dvb/v4l/videobuf-dma-contig.o] Error 1

Anyway, attached is a testing patch, which if applied to something
working earlier or fixed later, might give you some direction.

Since I don't know, if gpio settings for RF antenna input switch are
correct for card=60 and/or 109 that time, in case you get no picture
anymore on card=109 with it on recent, change TV gpio in saa7134-cards.c
to 0x0000000 and antenna_switch in saa7134-dvb.c to 1 in that case.

Cheers,
Hermann
