Hello, Sometimes I have noticed that just using /etc/init.d/alsasound start/stop gives the "in use" errors, but you might try $ /sbin/service alsasound stop then $ /sbin/service alsasound start then go into $ alsamixer and see if there are more sliders (specifically MASTER/PCM) then if you crank the vol way up you should get the test sound in $ system-config-soundcard -- This is an email sent via the webforum on http://fcp.homelinux.org http://fcp.homelinux.org/modules/newbb/viewtopic.php?post_id=102707&topic_id=24243&forum=10#forumpost102707
