Hi Balint, hi list!
Nice work creating a gnuradio source out of rtl-sdr, thank you for that.
But I've tested it using a Dexatek DVB-T Dongle which uses a FC0013 tuner and there are two issues I ran into.
First, there is the wrong handling of a return value when setting the frequency on the FC0013.
The attached patch integrates the Dexatek and fixes that issue.
But the second one isn't as easy to fix because I guess you would need some more insight into how a Gnuradio block is constructed to do that.
The following python std::runtime_error exception is thrown in grc everytime a graph using the RTL2832 source is started.
Wait delay: 11,130 ms
>>> gr_fir_fff: using SSE
Traceback (most recent call last):
File "/home/mad/gr/top_block.py", line 109, in <module>

AttributeError: 'baz_rtl_source_c_sptr' object has no attribute 'to_basic_block'
Perhaps you have some idea about that.
BTW, I'm using 220.127.116.11 Gnuradio with 2.7.2+ Python, your feaf6c commit of gr-baz and using stand-alone rtl-sdr the stick works well.
