Microphone recordings are empty

[alain]

OS (e.g. Win10): MacOS Monterey 12.1
PsychoPy version (e.g. 1.84.x): 2021.2.3 /2022.1.1
Standard Standalone? (y/n) : yes
What are you trying to achieve?: recording sound from the MacPro Microphone

The minimal script displays a “Speak now!” text message for 1 sec, and simultaneously opens a microphone component,
with device= Macbook Pro Microphone , no transcription, save onset/offset times, output =default, speaking start/stop times, no trim, channels = auto, sample rate = Voice, max size = 24000.

the output file correctly reports mic_started, and the recording folder and recording file is created, but there is no sound recorded, just a blank file of 1 sec duration.

Only error message in runner window :
||PaMacCore (AUHAL)|| Error on line 520: err=’‘what’’, msg=Unspecified Audio Hardware Error

Tried both with 2021.2.3 and 2022.1.1 - same results

Help please !

Hi I am re-posting this request, in the hope to get some help.
Did anyone succeed in recording sound through the microphone on a Mac recently ?

Please make sure your sound card is the correct version of this computer

I am having exactly the same issue on Mac. Did you find a way around it?

I am also having the same issue on Mac, any advice on this?

Hello
@Dogus @alain did any of you found a solution for empty recorded files ??
I’m having this issue in my experiment!

Hello all, hopefully someone found a solution for this issue and can help us
I’m trying to record audio from a microphone, but unfortunately, the files are empty. I have made several attempts to solve this issue, such as specifying the duration as 8 seconds when the length of the video is 8, but the problem seems to occur when I connect to the sound card (Scarlett 2i2). If I use the Mac without any sound card, it plays normally through headphones and records audio from the laptop.

I have a similar experiment that uses an audio component instead of a video component, and it works normally. What can be the issue, and how can I solve it?
