Ultralite and MacBook: audio dropped in playback?

[pjournel]

Hello to all,

I am the proud owner of an Ultralite mk3, I played with it a lot this week end. I am gladly surprised by the audio quality, even a guitar plugged straight in one of the two preamp sounds awsome.

Anyway, on to my problem: after recording a couple of tracks for my podcasts, I was listening to the playback through the headphones output on the Ultralite and the audio stopped after a soft beeping sound. I had to turn off and on the Ultralite to get it to playback properly in Garageband. Same thing happened a couple of minutes later.

Here is what I have in the log file:
Dec 15 00:30:08 pierres-macbook kernel[0]: ERROR: FireWire (OHCI) Lucent ID 5811 built-in: handleUnrecoverableErrorInt

Any idea?
The firmware says v1.00 at startup, I did not find any update on the Motu website, am I right?

Thanks in advance for your help,

Pierre.

Hello,

I am replying to my own post as I think I have now a solution!

After trying many things (installation of the latest driver, change of FW cable, etc...), by chance I turned off the Bluetooth on my MacBook (because the batteries of my wireless Mighty Mouse were dead and I wanted to try to go back to a keyboard+trackpad only operation) and bingo! My MOTU Ultralite mk3 has been rock solid ever since.

Just wanted to share this weird workaround: turn off Bluettoth on your MacBook if you want the FW interface to behave properly.

Strange but true.

Pierre.
