Edirol FA-66 FireWire Audio Interface not working

Hi!

I have a major problem: I just purchased an Edirol FA-66 FireWire Audio Interface and I was hoping to use with my 15,4" Macbook Pro (bought in May 2009). The device is known to use Core Audio driver so no additional installations were needed. It said on the manual of the device that you can just plug and play when using Mac.

But here's the sad story:

First I plugged the thing and it worked like it should for maybe five minutes, I could choose the device from System Preferences as Audio In/Out device. But then it just froze. I checked from System Preferences and it had disappeared from there, only built-in audio in the menu. I tried re-connecting the device but nothing happened for a while and suddenly after 15 minutes or so, the computer found the device again. But soon the same pattern repeated.

Reading some of the forums, I figured my problem might be cable-related. So I tried with another FW-cable with slightly more "reach" at the computers 800-port.

Once again device worked fine for the first two minutes but then the real problems started: first all the music related programs crashed one by one (iTunes, Garageband), soon System Preferences and Audio MIDI Setup followed. I checked from System Profiler and it had the notorious warning: "Unable to list FireWire devices". I tried rebooting and it was alarmingly slow.

The FA-66 was accompanied by two FireWire cables, but they were 6-6 and 6-4. Since my Macbook Pro has only 9 pin (800) I bought additional cables (9 to 6 / 800 to 400) for this purpose. Could it be that the interface is somehow not supporting the 800 port and that's causing the problems? You can power the interface both by bus or by a DC adapter. I tried both and got same results.

All this was repeated with numerous restarts and logouts and whatnot. I feel I have tried every possible combination already...

I upgraded to Snow Leopard recently and before and after that, searched for forums for any problems related to this device and SL. Since I found none, I decided to buy. Could this be SL-related?

Any tips on a fix or should I just take either my computer or the interface back to the salesman and demand my money back?

By the way, I tried using FA-66 with my old PPC iBook G4 with Tiger and it worked perfectly. And it's not even supposed to be supported for other than intel Macs! So it must be the Macbook Pro or the ports...?

Help, please. I need to get this thing working and I'm starting to panic...

No replies yet, but it seems they're not needed anyway. It think I got this covered!

Short explanation, in case someone faces the same problem in future:

It began to feel that the FireWire port was somehow messed up. I read somewhere that not-so-good cables can cause the FireWire-ports safety fuse to go off and mess up the bus, or in my case, the whole computer. So I did what seemed like a good idea and shut the computer down and removed the AC adaptor and battery and let the machine "cool down" for an hour or so.

Then I walked in to an Apple reseller and asked for a decent FireWire cable (third used during this scene). I bought one and tried it right there at the store. And it worked! Now the setup has been running flawlessly for 2 hours straight so I just might say phew!

The cable was of Belkin, the same brand that Apple Store sells, and it was three times as expensive as my previous ones but I guess it was woth it.

So I learned a lesson here:
Only buy and use quality cables and if something is not working, be suspicious about the cheapest part first.

Thank you, I hope this can help people struggling with the same malfunction.

Hey there, I've been having the same problem and Googled it and found you have the same problem. After plenty of messing around I found that the internal devices like line in/out etc. were set to a different sample rate. My FA-66 was set to 48k and the internal devices were set to 96k which caused a sync error within the FA-66 (dont ask me how). So if you type audio in your spotlight click on audio MIDI setup and make sure all devices are on the same sample rate you should not have this problem again (well I haven't yet anyway)
