Edit your crontab (~#> crontab -e) add a line on the 00's that runs the ntpdate application 00 * * * * /path/to/ntpdate pool.ntp.org :wq! to save it, and you will then be updated once an hour. On 03/29/2015 01:32 PM, kk6ecm wrote:

I have no problem running ntpd in my ACID servers that only have RTCMs interfacing with radios. But when I use usb sound interfaces (URI or usb sound fob) then I find that ntpd causes anomalies in the audio. Many people don't notice it but I do and anyone with a good ear will notice it and comment about the audio sounding strange and blame it on using a computer in the audio path.

Turn ntpd off and just use *ntpdate* once per hour and the strange audio sounds go away.
