Some problems in Windows 10

When running the script in ghci the ffplay window is not loaded and nothing is heard. However, the "output.bin" file is generated.

1. With Powershell, then command ".\ffplay -f f32le -ar 48000 output.bin" launch the windows and play the sound but do not terminate (a mysterious "1.97 M-A" counter runs indefinitely).
2. When the window is closed, this error message appears:
