The reason might be the following:
In some countries, the providers shift some channel center frequencies
by + or - 167 kHz to overcome interference with analog channels. Some
channel decoders can lock with such an offset. With the current driver,
the tda10046 can't.
So please try to modify the frequencies for the channels you can't
receive. There is a very good chance that this works.
The other possible reason is that the configuration data in your config
file are not correct. The TDA10046 honours i.e. a specified guard interval
and will not lock if it is wrong.
