That config file is optional, alsa doesn't require it.  You may want to
add one, try googling for info on your SBLive.  Since xmms works take a
look at the output plugin and see what it's writing to (perhaps directly
to /dev/dsp ?).

I think snd_emu10k1 is your SBLive module. Do you have sound on your motherboard
as well?  Maybe there's a conflict.  Check your "lspci -v" listing for devices
listed as "Multimedia audio controller"s.

There is a command called alsactl that may help you, take a look at the
man page and also see if you have a file:

/var/lib/alsa/asound.state

I'm not sure if I can offer much more help than this as I don't have your
hardware and I'm really far from being a Linux sound expert.

Good luck,

Jim
