Depending on the format you should be able to open the audio files in another program (like Audacity ) and verify if there are anomalies in the audio itself.
Other than that you could also try using an audio file that is known to not have issues. Try using one of the installed sound files found in Asterisk to see if those have similar symptoms.
Sometimes clicks and pops could be due to dropped packets. Try getting a pcap and see if any packets are being dropped between Asterisk and the phone.

Hi, I have an IVR that uses FastAGI, currently running on asterisk 13 (via the cleardevice/docker-cert-
asterisk13-ubuntudocker image).The problem: In between playing audio files there is an audible click. I'm not sure if somehow the audio files themselves contain clicks and for some reason I don't notice when playing them without asterisk but over the phone they're magnified, if it's a codec issue, if I'm doing something the wrong way, or what. Any help is greatly appreciated!
