I can confirm this, and I can also confirm that its not PulseAudio
related. I get the same clipping at the end of the same test sounds when
played via ALSA on the command-line, with PulseAudio disabled.

Title:
PandaBoard audio loud pops after playing sound over headphone jack
Status in “alsa-driver” package in Ubuntu:
Confirmed
Bug description:
On quantal images, most recently reproduced on panda armhf desktop
omap4 image from 20121005
This is easily reproducible when using the headphone jack and any
audio, even the sound test from sound settings easily reproduces the
problem. Usually after a sound plays, but sometimes at the beginning
of another one, there is a loud "pop" over the headphone jack. If I
switch the audio output to hdmi, I do not have this problem.
