When writing documentation, you might want to add that the ALSA-plugin in XMMS & Audacious requires a period time of 100ms instead of the default of 50ms, as otherwise the sou*click*nd is n*click*ot ver*click*y good. (A look at the current code of that plugin, to see how the volume control code can be fixed would be highly appreciated) > There are apparently some cases where it loses interrupts and then the > sound is garbled, my brother's investigating that at the moment, it > doesn't happen with my powerbook nor with my powermac.
