I haven't heard of "popping" issues with audio in quite a while, however, years ago it was attributed to certain (typically less expensive) audio equipment not handling the switch from DD2.0 (during pause, FF, etc) to DD5.1 when play is again initiated, and vice versa.
You can test this by setting the output format from your (sending) device to DD2.0 or PCM which would preclude the audio switching and hence the popping. Some sending devices also mute the audio during FF, etc, or "stay" on DD5.1 (the last audio format until another format is actually there), thereby also eliminating the popping.
