This is not a bug, it's just a setting: If you open the option dialog in xmms you can configure your Audio I/O plugin:
1) ALSA: you can choose to use a software mixer, or a hardware mixer. If you go for the hardware mixer you can select any mixer device (Master, PCM, Line, Synth, etc.) from your soundcard. 2) OSS: here you can only choose a (hardware) audiocard and mixer device. In the mixer tab, you can (un)check the option that causes XMMS to "use master, not PCM" -- xmms' volume slider should not mess with PCM but with master https://launchpad.net/bugs/41871 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
