Audio stimuli not playing when slider response is added

What are you trying to achieve?
I have two tones (high pitched and low pitched) to be played in each trial. They will be randomised and presented at different proportions (90/10 or 70/30 - conditions can be stable or volatile).

I added an audio stimuli and used an excel spreadsheet to represent the correct proportion of tones for each trial. These worked completely fine until I added the slider response.

I need participants to use the left and right arrow keys to continuously move their position on the slider throughout a trial to indicate what they think the correct proportion of high to low pitch tones is.

Main difficulties:

  • Marker position on slider to show initially without having to use the mouse to click on the slider
  • Not sure how to make the slider responsive to only left and right arrow keys (ideally, no mouse)
  • Making the audio stimuli play - I am not sure why it stops when I add the audio stimuli

Any help at all would be greatly appreciated! I’m fairly new to using psychopy
