[Hackrf-dev] sources of audio underrun?

[Chuck McManis]

Hi all,

I'm building a more sophisticated FM receiver in grc and I find I'm getting
regular audio underruns (aUaUaU ... ) they come in bursts. My CPU
utilization is like 33 - 40% for 3 of the 4 cores, maybe 70% for the fourth
one. What techniques can I use to avoid audio underruns?
