Help understanding log file message "SND: audio underrun"

edited January 2020 in KiwiSDR Discussion
A users turns up with the name "BEVERAGE" from 188.246.73.26

I then get a large series of SND: Audio underrun

Is this suggesting someone had connected with a very poor bandwidth and then audio overruns are a symptom of that?
Why do we see so many (number 50) and they continue as I type.

Can you help me understand the significants of this please, as they continue as I type (now into 60)

Thanks Dave
