[arm-allstar] Choppy audio

Sun Apr 18 15:13:59 EDT 2021

*I'd try running a ping test and see if there is an internet issue while 
the issue is happening. Also, over-deviated audio that clips can make 
the channel driver go into a non-linear state (for lack of a better way 
of saying it) and cause that issue. The agenda for my original question 
was that some of the hubs like 2560 on Friday nights get over 150 
connections and the Pi4b begins to run out of gas at that point. So, I 
wanted to make sure the issues you are experiencing are not on the 
"other" end of the connection. The East Coast Reflector has experienced 
similar conditions as well.

Sometimes several in a minute, sometimes only one or two every few minutes. For a while I thought it was the Pi overheating and throttling itself but I do not think that is it.
