That's not so surprising, the same tuner is used for analog TV and DVT-T.
Then I think the dvbscanning end with a frequency actually used by a
local tv.
Yes, i think so too.
with spurious input from remote ir device (actually not connected).
HU?
Perhaps nasty things are happening here.
The radio chip tea5767 must be connected to a line input of the
SAA7134. If the video input works including sound, you just need
to change the .amux entry to LINE2.
done, but I got only noise.
If you hear noise, i suspect that the signal routing is correct.
Just to exclude the other possibility: The card has a sound input
and this works with .amux=1?
With .amux=1 (TV) the card output the tv sound.
With .amux=LINE1 no output at all (S-video e composite not connected now)
In first time I didn't notice the difference because the tv also emitted
noise from audio as from video.
The card should have a separate antenna input for radio. Did you
connect something?
Yes, the antenna is connected. But the program seem unable to change the
frequency of radio tuner.
That's a bit strange. Please set the debug option for the tuner module and
watch the kernel log.
I need to study the MT352 datasheet again. Maybe the tuner needs to be
programmed through it as it is with the tda10046.
I had a look. Things are different but it seems to be possible to program
the tuner through the MT352. But i don't think this is right.
What is the exact tuner type? is it a TD1316A?
Please have a close look at the card, ist there an analog switch IC,
like the 4052 / 4066. Normally it is in a 14 or 16 pin so dip package.
If yes, are you able to trace its wires?
