angel12: As far as I can tell in GNOME right now, you can't. This is a bug and may or may not already be filed. GNOME uses some magic from ALSA to determine which channel is the "master" channel, so it may also be a bug with your soundcard driver.
This bug refers to the inability to raise the volume, despite lowering it working fine and affecting the correct channel. -- Volume keyboard shortcut fails to increase volume https://launchpad.net/bugs/36302 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
