My favorite XP Volume Control replacement:
Quick Mixer controls Main-Volume, Main-Treble, Main-Bass and up-to 16 playback audio sources! Quick Mixer gives you access to every available playback mute on your sound-card. Quick Mixer gives you access to the first on/off check under Advanced, Other Controls.
Quick Mixer allows you to create 10 audio profiles and optionally starts up with a default profile. Quick Mixer scans your sound-card's mixer-line to offer you only the correct playback sliders.
Quick Mixer is freeware.
