where is alsa stuff at www.fedora.us?

[Robert P. J. Day]

  wanted to play with ALSA stuff on my severn system, so
i checked www.fedora.us, and i didn't see any alsa-related
rpms there.

  pretty sure i can get them from over at freshrpms, but
i was just curious about their absence from fedora.

p.s.  what's the philosophical difference between freshrpms
and fedora, both of them being repositories for add-on rpms?
