Sorry its taken so long for me to repost about this, I've been busy...I got
the information about my sound hardware using the command you suggested:
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
Subsystem: Giga-byte Technology Device a002
Flags: bus master, slow devsel, latency 32, IRQ 16

I looked and my motherboard is a Gigabyte GA-MA78GM-US2H. I was also
incorrect on my first post, I tried that same video again, still in VLC, and
it had the same issue as the music. I also tried Youtube, same issue. I
tried changing VLC's audio output, I tried updating the ALSA drivers, and I
tried using XMMS, all had the same issue with the "skipping" audio.
Here are the contents of my user.log file:
