Hello!

I noticed a problem with rtl_fm and r820t tuners. In few words, it doesn't matter what value of gain you set with the -g parameter. The r820t tuner will be always at its lower gain, this is deaf as a doorknob.

Otherwise, the same dongles works fine with GNU Radio or GQRX for example, and gain can be set without problems.

rtl_fm gain works nicely on e4k tuners.

Someone else have noticed this?
