Does it do this all the time or only after the system has been
suspended and resumed? If so, take a look at
http://www.freebsd.org/cgi/query-pr.cgi?pr=55395. I know Orion has
looked at it, but I don't know when he might have a fix for it.

You might check the value of hw.snd.pcm0.ac97rate. If it is not 48000,
try setting it to that value.
