I cannot record audio from the microphone using the builder. Audio files can be generated, and the length is what I set to be, but the audio file is completely blank. I’ve tried several things. I’ve set audio library to [‘pyo’, ‘sounddevice’, ‘pygame’, ]. I’ve set the audio driver to [‘directsound’, ‘portaudio’, ]. Before I did these, all .wav files I got are 0 sec long, and are 44 bytes. Now it seems to be improved (I can make 2 sec recordings, for example), but the audio files are blank. I’ve also tried it on Windows 7, where I still get 44 byte files. I am using 3.1.4 on both computers.
Thank you so much!
OS : Win 7, Mac OS 10.14

**What are you trying to achieve?: make recordings
**What did you try to make it work?: updating to the latest Psychopy, changing audio library and audio driver.
**What specifically went wrong when you tried that?: On Windows I got 44 byte long wav files. On Mac OS I got wav files of designated length, but there is no sound at all (always 0).
