System/Preferences/Multimedia Systems Selector/Audio set Plugin to Pulse Audio. noticed this part in your multiple sound solution guide under default soundcard title. that "multimedia systems selector" is not in system/preferences in 8.04 and 8.10 (2 i have tried) and has to either be enabled by right clicking the main menu and choosing >edit menu ,or by using the "gstreamer-properties" command in the terminal. thought this may be usefull to add to your guide Markbuntu!!!!
