If you're reading this, chances are, you are in a hurry to find the answer to this problem, so I'll make a long story short...
Problem: When performing an Edit To Tape in Final Cut Pro 7, I discovered that I could not record a stereo audio track to tape during an Insert Edit. Since I knew that my sequence settings and hardware connections were correct, I was baffled. This happened with both the Aja IO HD and Matrox MXO2 when transferring to a UVW 1800 Beta SP machine. After reading a few forums, I noticed that this happened on other IOs involving Final Cut Pro. Thanks to the friendly, helpful people at Aja, I learned the following fix.
Solution:
1. Open the Audio/Video Settings under the Final Cut Pro menu
2. Click on the device control preset tab
3. Find the setup you are using and click the edit button
4. If your audio mapping is set to 8 (FCP's default setting), then you are probably not getting audio
5. Set Audio Mapping to 2
This should solve your problem if you have a similar setup.
If this was helpful to you, please let me know. I like to make a difference. :)
