Standalone PsychoPy 2021.2.3
Primarily trying to get code that worked before on the same version (reinstalled and code from backups) to work again. We have identical systems running the same code that work fine.
it keeps complaining about not being able to find a file type.wav. everything is as it was. The excel file to run the task has all the paths to the audio files. There is no file called “type.wav” (in case it is searching for a a file called type.wav instead of a file type *.wav.
Failed to load audio: setSound: could not find a sound file named type.wav
As i ran out of ideas I did a re-install but even with this fresh install there still seem to be information that is kept, as it still loaded up with old scripts and some file paths. Anyone know where stragglers are hidden as I want to get everything out and really start fresh.?
In the mean time starting from zero :
I am just making sure I can play a sound at all.
After that I’m trying to get PTB to work
Also trying to get an M-audio M-track solo to work because i want stable latency.
step 1
try if it want to beep at all:
from psychopy import prefs
prefs.hardware[‘audioLib’] = [‘pyo’]
from psychopy import sound
AMP = 0.5
audio_path = r’pathto/beep.wav’
acoustic_stim = sound.Sound(audio_path)
acoustic_stim.setVolume(AMP)
acoustic_stim.play()
*and this works: 
*
step2
*however if i set :prefs.hardware[‘audioLib’] = [‘PTB’] *
# with these settings
silence.:sad
When I use the M-audio SOLO box it does show up in the pull-down (speakers M-audio duo and solo), it is set in the windows env as well. No errors when i run it, just no sound.
any ideas welcome!
