I've now pushed a change to librtlsdr that
disables the AGC by
default, and added the function rtlsdr_set_agc_mode() that can
be used to re-enable it again.
This works well. I use rtlsdr_set_tuner_if_gain() now to compensate
for the gain loss and found a bug there: The i2c repeater needs to
be enabled.
