So I made this behemoth of a thing to present visual and auditory versions of the n-back task in an fMRI setting. The test alternates between showing single letters on the screen with playing audio files with a recorded voice saying the letters. Presentations are 4-16 letters long of either visual or auditory stimuli and the task is either 0- or 2-back. Every 4th letter the test waits for trigger.
The problem is: a couple of minutes into the test Superlab stops playing the audio. The test moves along as it should, switching backgrounds to indicate task, presenting visual letters when it should, but the audio is gone. This does not happen when simulating the trigger by pressing a key on the keyboard.
I will stop here certain that you need more information but are in no need of a wall of text. So please, any ideas? What information would you like me to provide?
