This looks good, but it appears that the OSS compatibility modules are
not loaded. These can be enabled by editing /etc/alsa/alsa-base.conf:

The following link provides instructions on how to how to configure the
alsa modules for this card and Debian:
http://www.alsa-project.org/alsa-doc/doc-php/template.php3?company=Creative+Labs&card=Soundblaster+Live+Value&chip=EMU10K1&module=emu10k1#modp
Are you by chance using DevFS? Does /dev/mixer exist? What are the
permissions on it?
