Hey Folks, I need some help here. I've tried (seemingly) every possible combination of data types I can come up with at 1:30a.m. and nothing seems to work. This is the call currently: sndErr = SPBSetDeviceInfo (myInRefNum, siVoxStopInfo, (Ptr)&astruct.onOff); where astruct = structure of {int onOff, trigger, delay}. I have tried substituting various other data types (3 ints, pointers to struct, pointer to ints, etc...) and nothing is working. Upon execution, I get an error -231 = Unknown type of Information. I'm hoping that I'm doing something dreadfully stupid and anyone's help would be useful and appreciated. BTW, I am using sys 6.0.7 with TC 4.0.2 (with the new headers) Thanks, Kevin Kinsey UCNS University of Georgia Athens, GA kinsey@athena.cs.uga.edu

This is why you're getting errors. It works under System 7. Secondly, here how to turn VOX stop on with delay. void SetVoxStop(short value) { short VoxData[3]; OSErr err; if (value > 0) VoxData[0] = 1; // turn it on else VoxData[0] = 0; // turn it off VoxData[1] = value; VoxData[2] = GetVoxDelayData(); err = SPBSetDeviceInfo(gSndInputRef, siVoxStopInfo, (Ptr) VoxData); if (err) AlertUser(err); } Jim Reekes, E.O., Mac Toolbox Engineer (working on the Sound Manager)
