Ack! Did they actually do this???! It's like having a 5 speed transmission
and letting you select only 3 gears! If the other problematic FV3Ks have
similar configs, that may explain why it works with the FV2K settings.
If all the audio is indeed going through the 4052 analog mux, then the TV
setting may also go through LINE2 with gpio mask 0x0000.
Does anyone (Gerd? Gunther) know whether the radio decoding is done by the
TV Tuner block? If so, then it may share the same audio config as the TV
input.

By right, the SAA7134 has electronic muting logic (hence the first
card_has_audio(dev) test. This may be bypassed if audio is indeed going
through the external mux.
