Hi Becca,
I have single physical microphone.
I’m going to make several recordings throughout my experiment in different routines. So I add one microphone component in one routine, add another microphone component in another routine, resulting in several microphones in my experiment.
But it works only when I include one microphone component in one routine, when I include more than one, it gives the error:
given audio library ptb:
PTB-ERROR: Failed to open audio device 7. PortAudio reports this error: Invalid device

PTB-ERROR: This could be, e.g., due to an unsupported combination of audio sample rate, audio channel count/allocation, or audio sample format.

1.7193 WARNING We strongly recommend you activate the PTB sound engine in PsychoPy prefs as the preferred audio engine. Its timing is vastly superior. Your prefs are currently set to use [‘pyo’] (in that order).
