When I run this minimal example, everything works fine.
import sounddevice as sd
import numpy as np
FS = 44100
sd.default.device = 45 # This is an ASIO device
def run():
print("Running playrec...")
sd.playrec(np.zeros((FS, 1)), FS, channels=1)
print("Done!")
if __name__ == "__main__":
run()
But when I introduce the DearPyGui framework and try to execute the same function from a callback I get an error.
import numpy as np
import sounddevice as sd
import dearpygui.dearpygui as dpg
FS = 44100
sd.default.device = 45 # This is an ASIO device
def run():
print("Running playrec...")
sd.playrec(np.zeros((FS, 1)), FS, channels=1)
print("Done!")
if __name__ == "__main__":
dpg.create_context()
with dpg.window():
dpg.add_button(label="Run playrec", callback=run)
dpg.create_viewport()
dpg.setup_dearpygui()
dpg.show_viewport()
dpg.start_dearpygui()
dpg.destroy_context()
Running playrec...

This only happens when I try to use an ASIO device. For example, MME works fine. Does anyone know why this is happening?
Interestingly, if I put the import statement inside the function. It works. But you have to remove the initial import on line 2, if it's there it still breaks.
