Mac OSX standalone voice record problem

Hi everyone,

I am once again trying to get a voice recording application to work 
appropriately in an OSX standalone. I develop on a G4 dual 1.42 Ghz, 
Rev 2.02, OSX 10.2.6 and deploy on both 700Mzh G4 eMacs and 500Mhz G3 
iBooks, same OS. In the development environment, everything works just 
fine. However, when I build a standalone and try to record through an 
attached microphone (plantronics Audio 90 with Griffin iMic), the 
recording tends to be truncated and jumbled up. In other words, if I 
were to say "1,2,3,4,5" I might get "3,4,2" as a result -- very 
strange. Also, I have noticed a tendency to limit the recording file to 
about 4 seconds total.

Several months ago I thought I had licked the problem by making 
absolutely sure the recorded file was located outside the application 
package. This workaround now seems to have no effect. The frustrating 
part is that we might occasionally get a perfectly normal recording, 
but the next time we try, we get the jumbled up results again. It just 
doesn't seem to be consistent.

We intend to deploy a recording application in our language lab, so 
that students may record their voices and the files can be saved so 
that instructors can hear the students' output. Occasionally, the 
program can be used for oral testing. However, if the recording is 
unstable at all, the program is useless.

I have checked the bugzilla database, but have been able to find 
anything regarding this problem there. Before I post it on bugzilla, I 
wonder if anyone out there has found a consistent solution to the 
problem.

Thanks,
Dan
