The problem seems every time I raise the sample rate above 8 mhz approximately, for example when I record a dvb-t signal with gqrx.
The SDR is a hackrf and, at the moment I am finding myself with the oooo because I am only recording, if I tried to do another type of operations I am almost sure that other types of bottleneck problems would appear, uuuu, etc ...
If I try to use 16 mhz to avoid dc offset, the problem is multiplied by two
Best regards
