The following intermittent error occurs when using mpg123 while PulseAudio daemon is running:
ALSA lib pcm.c:7963:(snd_pcm_recover) underrun occurred

Mpg123 uses faster buffering than PulseAudio's default configuration, resulting in audio chop.

The remedy was found here:

Reconfigure PulseAudio buffers in /etc/pulse/daemon.conf

 default-fragments = 5
 default-fragment-size-msec = 2

Restart daemon:
pulseaudio -k
