Hi everyone, I just got my new (first! ) Macbook Pro recently and also a pair of LaCie speakers. Unfortunately, these speakers work via Firewire 400, and the new MBPs only have a FW800 port. So I got a 400 to 800 FW adapter, hoping to finally hear music out of something else than the built-in speakers. To my surprise, despite all the reviews on the net regarding the ease-of-use of these speakers, they don't work. Let me be a little more precise: - I plugged them in correctly, according to the instructions: secondary speaker in the main speaker, FW400 in the adapter and adapter in the FW800 - They are powered on: the blue led at the bottom of the main speaker is on - You can hear the specific sound of speakers that are on - If I connect also the line-in cable to the main speaker and to the headphones jack of the MBP, I get sound, only at a relatively poor quality - The speakers don't show in the System Preferences - Sound. My only other option to try them is on a PC (haven't tried it yet). Any ideas? All of the above do not indicate any issue with the FW port, the speakers or the adapter. Thanks for the help.
