Trouble getting 3 sounds play at certain routines each. SoundFormatError

[Maria_Myrto_Petratza]

OS (e.g. Win10): Win10
PsychoPy version (e.g. 1.84.x): PsychoPy 2021.1.2
Standard Standalone? (y/n) yes
What are you trying to achieve?:
I am trying to create a digit span task, where the participants will see sequences of numbers, then have 20sec after each sequence to answer typing numbers with background music as a distractor. I need different pieces of music at trials 7-14, 15-21, then a different piece for trials 22-28

What did you try to make it work?:

Loop allowing to display a music background during every routines of that loop

Many thanks for your replies !! I managed to do something a bit betweeen both. If anyone else need it --> : I inserted a routine at the beginning of my loop in which I added the sound component (let’s call him “sound_1”) with no stop time and a code component in which I put in the Each Frame tab if t >=0: sound_1.pause() continueRoutine = False I had to this because between the 1st and the 2nd routine, the sound was starting from the beginning again , which was not…

I used this solution adding routines with a sound component and a code component on the spots at the flow where I wanted the sound stimuli to start, and a code copmponent to the consecutive routines following (where I wanted the sound to be, for instance to routines 14-21) as is said to the solution I linked above.

What specifically went wrong when you tried that?:
The experiment can’t be ran. However, it worked when I only had one sound.
The message is:
psychopy.exceptions.SoundFormatError: Tried to create audio stream 48000_2_128 but 44100_2_128 already exists and win32 doesn’t support multiple portaudio streams

Experiment ended.

I’m posting the whole traceback too:

Could somebody please help me figure this out? Many thanks in advance!

All of your sounds need to have the same bit rate. You can edit this in Audacity.

Thank you for the response! I’ve been trying this by the “save as” option, however in a .wav format there is no such option. Perhaps I’m doing something wrong. I’ll keep trying! Thanks again!

Try Tracks - Resample

[Maria_Myrto_Petratza]

I fixed it by changing the Hz, choosing the same number for every track. Thank you so much!
