[App_rpt-users] K2ETS Audio Clicks

[lengriff at optimum.net]

The K2ETS repeater(s) [ 2M-27274 & 220-27273 ] are running on a Pi-2 under
Debian as a dual node system. I'm using a Class10 SD card.
We've had an audio issue for more than a year now, and I'm unable to track
down the cause. [ sample attached ]
After a re-boot, the audio is perfect. Over the course of a month or so,
small audio interruptions begin to appear, becoming actual ' clicks '. It
appears that the
processor is becoming overloaded, and the DSP is affected. Members have
named it our ' Galloping Ghost '.
Sometimes, just clearing the log file and re-starting asterisk fixes it, but
usually a re-boot is required.
I'm stumped. I plan on re-installing Debian, and going to a Raspberry Pi-3
in the spring.
