Hi,
slowly there is some light here:
1) GPIO
Gerd, please apply this patch, as Pinnacle is autodetected as card=0x27,
but we need GPIO from card=0x34.
Probably this explains why radio only worked for some people
(there was a chance of 1/2 to get it "right").
2) MSP, simple=0/1, msp34xxD vs. msp34xxG
When I set "simple=0", I get radio for this card:
bttv0: detected: Pinnacle PCTV [card=39], PCI subsystem ID is 11bd:0012
msp34xx: init: chip=MSP3410G-B11 +nicam +simple +radio
bttv0: pinnacle/mt: id=2 info="PAL+SECAM / stereo" radio=yes
MT2032: Companycode=4d54 Part=04 Revision=04
With "simple=1", I only get the very strongest stations (or mute).
Conclusion: msp34xxG does "auto mute" with radio short programming.
Gerd, I would propose to _not_ use radio short programming on msp34xxG,
as automute is a very unexpected effect. I want to hear static from
my radio ! So just treat it like 34xxD.
3) MT2032
The radio code in tuner.o for mt2032 was never tested,
so I wonder it worked at all :-)
- here it shows aliases for strong stations
- the aliases are even overlayed with a faint 2nd station
- some stations are not tuned at all (very noisy).
4) There are variants
case 2:
info = "PAL+SECAM / stereo";
btv->has_radio = 1;
break;
case 3:
info = "NTSC / stereo";
btv->has_radio = 1;
break;

Can you please re-evaluate using "Line Out" from the card directly?
We need to rule out, there is a problem with btaudio (even if it works fine
for your TV sound).
Of course when we get radio via line out working, the next would be radio
via btaudio.
Hm...
OK. I get an almost decent signal/audio with line out. for simple={0|1}.
Does it tune the right stations?
It seems there is work left on mt2032 now...
(I implemented mt2032 radio code in the blue, without
a possibility to test; only now we found the bugs in msp3400.c
and gpio settings...)
Except for the hiss. I must try the onboard via audio some day...
There is still some annoying interference. I can't tell if this is
a problem with the card, code or my wiring. It does not appear when
watching TV.
I have made two samples available:

http://home.online.no/~grsoerda/tvsound-lineout000.ogg
Will have to crash now...
