As the other guys has said, there a big chance that oss module is loaded.
This happen not by any mistake, I really did not figured out why, but
the default
instalation of sarge comes with discover and hotplug enabled by default.
So what happens? Discover is loaded first, it loads the oss module for sure.
Once you install alsa-base, it puts all oss modules in
/etc/hotplug/blacklist.d/alsabase
this prevents hotplug to load oss modules, but doesn't stop discover.
you need to edit /etc/discover.conf and add: "disable pci"
and discover will no load oss modules anymore, leaving the road free for alsa.
Anyone can tell me why there is 2 daemon for autodetecting hardware? And both
enable by default!?
