Issue between 2018.02.05 and 2018.03.12 #175

From https://github.com/pothosware/PothosSDR/issues/50

I installed my LimeSDR PCIe on a new PC and installed the latest build PothosSDR-2018.03.12-vc14-x64.exe . In GQRX I can listen at 40MS/s, but anything higher gives me tons of noise, the spectrum becomes all yellow.

In my own C++ program using SoapySDR, I often have errors while receiving on one channel (readStream returns -1), and when I try to use 2 channels, I get usually 3 warnings Channel alignment failed and then I can't receive anything.

After updating the drivers, BIOS and all, I uninstalled Pothos and installed the previous build PothosSDR-2018.02.05-vc14-x64.exe , like on the previous PC, and everything went back to working normally.
