Play and record sound simultaneously

[Python 3.7.3] [Debian 10] [Psychopy 3.1.4]

I’m wondering if it is possible to use Psychopy to record and play sounds simultaneously, in a non-blocking fashion. In my experiment, subjects hear an auditory sequence of short sinusoidal tones (beep), and they have to give synchronized responses, either manual or vocal.
Manual gives me no trouble. However, when I try to record vocal inputs with the ‘microphone’ module, it seems to clash with the ‘sound’ module.

Does anyone had a similar experience with this ?
I tried to use both ‘pyo’ or ‘sounddevice’. ‘Pyo’ is good but seems to prevent simultaneous ‘playback/record’. ‘sounddevice’ seems perfect but loading the ‘microphone’ module automatically switches to the ‘pyo’ audio library.

I’m considering using the solution suggested here, i.e., use a personal audio library, and get rid of the ‘microphone’ psychopy module. Does it sound right to you ?

Microphone recording not ending properly

That sucks. Several months ago after coming to the conclusion that pyo sucks, I had done a little digging and came up with a program myself to use for playing and recording audio. The recording program is modified slightly from a post on github by slorian, so he deserves any credit there, I wrote the player code myself. If you’re coding your experiment yourself you could consider using this, though it comes ‘without warranty’ It could also be added in a code component with some …

Thank you very much !
