Eyelink: Turn off calibration/validation beeps
The Eyelink system by default plays (really annoying) beeps during calibration and validation. This annoys me perhaps more than it does the participants, since I have to listen to it all day, and it's a long experiment so we have to calibrate several times over. There are other sounds played during the experiment, so just muting the master volume is not an option.
Can I turn these sounds off through PyGaze? If so, how?
I have been able to do it when using the SR Research pylink library directly, as documented in the Eyelink Programmers Guide:
pylink.setCalibrationSounds('off', 'off', 'off')
But is there a way to do this through the PyGaze eyetracker object, or do I have to dig into it to get hold of the pylink Eyelink object that it creates?
Thanks in advance for any help.
