Just an update on this. I received my Turtle Beach Riviera card and it seems
to have fixed all my audio problems! I modified the kernel drivers, and had to
change one line in .asoundrc; from device 4 to device 2; and the problems
described above are gone!
Thanks for all those that helped.  I can't say for certain that the on-board
audio hardware was the cause, but a $25 replacement is a good enough
solution for me.
