have looked up some details and agree with Mauro here.

First, Avermedia cards on the saa7134 driver are all identified safely
by PCI subsystem. No problems and we deal with GO 007 FM tda8275c1 and
not the later tda8275ac1.

Assaf reported the radio working, _but later_ he reported also that the
frequencies are off. I saw the same later too and lots of ghosting radio
stations with Asus P7131 Dual until Hartmut added radio IF support for
saa7133/35/31e and all tda8290 tuners with the 5.5MHz filter.

LINE1 was never changed for radio on the GO 007. Assaf's patch came in
with a bunch of patches Nickolay collected that time.

Then Hartmut added correct basic radio IF support and I guess this did
"break" the previous "ghost" radio.

Else there was only this change unrelated to radio.

------------------

And furthermore it has .gpiomask = 0x00300003
and gpio21 is set high for radio and low for TV.

		.radio = {
			.name = name_radio,
			.amux = LINE1,
			.gpio = 0x00300001,
		},

That is why changing the radio amux to TV just works.

Cheers,
Hermann
