error after changing psychopy PTB sound preferences about eeg-expy

[JohnGriffiths]

Thanks. Will look into this. I also looked into this unsystematically when tidying up the auditory experiments, and found different issues with PTB (additional installation requirements, and apparently worse sound quality). This is a different problem, but in any case we should review the PTB option properly, as psychopy does seem to have a major preference for it.

I have tried to run like in this code I add here. But it seems that this issue has been presented before.

@andraderenew As said before in #16 (comment), this issue was fixed in #101. Make sure you're using the latest commit.

[andraderenew]

I am using the latest commit. I deleted all I had previously and reinstalled from source.

[danielemarinazzo]

If the problem still persists, try to run psychopy before eegnb. Once you are in psychopy go to preferences->audio->audio library and puy pygame or pyo on top (you should have these installed), and leave ptb and sounddevice somewhere lower in the queue.

@andraderenew I can see from the stack trace that you're not using the latest commit. You may have files from the old commit still around.

Specifically this:

File "/Users/andraderenew/eeg-notebooks/eegnb/cli/introprompt.py", line 132, in main
run_experiment(experiment, record_duration, eeg_device, save_fn)

This is the line that was wrong before and was fixed, and is indeed corrected in the latest commit.

[danielemarinazzo]

thanks for checking, I'll use the last commit! I was pointing out a solution that worked for me when everything else did not, in case @andraderenew is actually using the last commit.

@danielemarinazzo Sorry I tagged the wrong person, I meant to tag @andraderenew.

[andraderenew]

all solved!!! thanks for the comment on PTB and psychopy. I had to set preferences with python console because with the GUI it crashed.
