Choppy sound could indicate a wrong sample rate. Jay used speaker-test, which uses 48 kHz by default, but most music files are 44.1 kHz, so it looks as if switching the sample rate does not work correctly. > Alas the missing mixer makes the whole affair not quite usable yet: The > LaCie FireWire Speakers are very loud; too loud for the desk or living > room. On OS X, I had their volume pulled down to the lowest mark. Attached are .conf files that enable software volume emulation for devices "default", "front", "surround40", and "surround51", but not "hw". Put them into /usr/share/alsa/cards/ (or wherever your distribution puts them).
