Currently gnome volume control has two mixers for the same card. One for OSS and the other for ALSA. Since fedora uses ALSA for most of its sound this should be the primary and only mixer. Yes I play Wolfenstein and AA so I need to adjust the OSS sound levels. Their sould only be one ALSA mixer with a software hack that also adjust the oss levels at the same time. This is going to be confusing for newbies if they see two mixer controls.
