To chime in on the sound issue, I get seemingly random distortions or
screeches during playback. A sure fire way to cause it on demand is to
do a sysctl -a. I've also found that taking the battery out and running
on A/C only reduces the frequency of the distortions.

You may have gathered that this is a laptop based on the fact that it
has a battery. Sound is provided by an Acer Labs M5451 using t4dwave driver.

On the other side of the spectrum, sound plays back perfectly on my
workstation.

Slaves are generally expected to sing as well as to work ... I did not,
when a slave, understand the deep meanings of those rude, and
apparently incoherent songs.  I was myself within the circle, so that I
neither saw nor heard as those without might see and hear.  They told a
tale which was then altogether beyond my feeble comprehension:  they
were tones, loud, long and deep, breathing the prayer and complaint of
souls boiling over with the bitterest anguish.  Every tone was a
testimony against slavery, and a prayer to God for deliverance from
chains.
