The hardware information page here:

Refers to the gr-baz RTL-SDR driver, which, IMHO isn’t as good as the
gr-osmosdr drivers, here:
AMONG OTHER THINGS THE GR-OSMOSDR DRIVERS USE A BETTER (LESS BUGGY)
E4000 TUNER IMPLEMENTATION, AND ALSO SUPPORT MULTIPLE DEVICE CLASSES IN
A UNIVERSAL WRAPPER:
FCD, RTL-SDR, UHD, OSMOSDR, and their own
remote-tcp implementation are all supported for their “source” class.
