The problem is that by enabling the direct sampling mode, the RTL2832
is forced to low-IF mode and only one ADC is enabled.
For your purpose, the device needs to be in zero-IF mode, which
normally wouldn't be used if a low-IF tuner like the R820T is attached.
Please see the attached patch, if you call rtlsdr_set_direct_sampling
with 1 after applying it should work.
