[linux-audio-user] Upgrading ALSA on Mandrake 9.1

Hello all, I've got an odd one here - I'm trying to upgrade ALSA on a Mandrake 9.1 box. I did this before on another (upgraded to 0.9.2) and it worked fine, but on this one upgrading the RPMs seems to have no effect. I installed these RPMs with urpmi: libalsa2-0.9.5-1mdk.i586.rpm libalsa-data-0.9.5-1mdk.i586.rpm kernel-multimedia-source-2.4.21-0.16mdk.i586.rpm But if I do: service alsa restart I get: Shutting down ALSA sound driver (version 0.9.0rc8): [ OK ] Starting ALSA version 0.9.0rc8: cs46xx. [ OK ] I've tried rebooting. Any clues? Have I missed something obvious here? Thanks Daniel
