Audio lost through firewire

If we send video out through firewire then we get the video signal but no audio, then when we change video output to none, audio returns via built-in audio. How do we get the audio to stay on when outputting video to Firewire (audio goes off when output to Desktop Video as well). This is with projects sent from FCP to STP. FCP audio plays fine through Firewire.

I have the same problem here, having spent much time getting a workflow sorted in order to use Soundtrack Pro 2.02 via exported markers from Final Cut for a dubbing project it seems that when video is output onto a second screen the audio disappears (desktop preview).

Also get a message after about 5 seconds saying that ST Pro can't play the audio due to hard disk not fast enough (I can run a 36 track mix in Logic..) and to remove 'Long files' or quit apps, but am not running anything else and I only have one audio track!

Another thread with a similar issue suggested rebuilding permissions, this I have done and verified drive, plus tried using an external drive for files too. No difference. Seems interesting that the possible link is due to FCP export? I noticed at one point that ST was still referencing the original clips in FCP even after making them independent and exporting as separate files.

Also can't see the Timecode hud when it is on the second monitor when video is playing there (shows fine on desktop on second screen). It's vital to be able to see the timecode over the presented video as this is being fed to a dubbing cabin.

Come on Apple give us some support here as it seems rare that such problems get any direct answers from you! I've just paid a packet for the Final Cut Studio and Logic Studio suites and our whole production is being delayed by these issues (and many others!)

Ok I have got audio now playing with both screens playing video. The answer seemed to be to export the sequence from the browser in FCP using the right click options and Export > For Soundtrack. I made the movie self contained. This file can then be imported into a new project in ST.

The manual suggested using the Send To > ST multitrack project option which creates a ST project file for you, but as found before then the audio won't play when using video out..

Either this is a bug or maybe has something to do with the export file format, either way it's a bit shabby.. and I still can't get to see the timecode hud over the video out display..
