I did a softboot from windows (after tuning the radio) and disabled the init of tda9887, but
nothing changed, so I think the radio problem is somewhere else.

Does radio work on ANY tvcards at this time?

I found that I got no sound when removing setvolume in msp3400.c, but I
see that it is called many times with different parameters, like this:

msp34xx: AUDC_SET_RADIO
msp34xx: switching to radio mode
msp34xx: setvolume: mute=off 0:0  v=0x00 b=0x00
msp34xx: AUDC_SET_INPUT(1)
msp34xx: VIDIOCGAUDIO
msp34xx: VIDIOCSFREQ
msp34xx: setvolume: mute=off 0:0  v=0x00 b=0x00
msp34xx: AUDC_SET_INPUT(1)
msp34xx: VIDIOCSAUDIO
msp34xx: setvolume: mute=off 65500:65500  v=0x72 b=0x00
msp34xx: setbass: 32768 0x00
msp34xx: settreble: 32768 0x00
msp3400: FM-Radio setstereo: stereo
msp3400: setstereo final source/matrix = 0x20
msp3410: setting mode: 10.7  FM-Stereo Radio (0x0040)
msp3410: current mode: 10.7  FM-Stereo Radio (0x0040)
msp34xx: scart switch: in2 => 0
msp34xx: setbass: 32768 0x00
msp34xx: settreble: 32768 0x00
msp34xx: setvolume: mute=off 65500:65500  v=0x72 b=0x00

Here both 65500:65500 (what I specified to fm), and 0:0 is done here.
Why is it called multiple times?

My theory is that somewhere in msp3400 after tuning the radio is
working, and then something else executes and disables the sound (i can
hear it for 1/2 sec. after each tuning). Since I can hear it, I thought
it might be the daemoen-thing that does something wrong (it may delay
a bit before it is called)
