Which kernel did you come from?

Hmm.

What is the result when you do a
cat /proc/sndstat
?

This sounds like the PC speaker signal *may* be physically connected to an
auxillary input on the soundcard. Does the PC in question have an internal
speaker? Does the internal speaker work before and/or after loading of the
sound module?

It may be that the aux input the speaker is connected to happened to be
turned down in 2.0 by default. Between 2.0 and now it is possible that
this input defaults to being turned up for some reason. The driver has
undergone considerable changes during 2.1.x.
