Should be fixed in 25.07.4
Hello, sadly it does not seem to be fixed. I have exactly the same Problem and I am on Version 25.07.5 (7172b2d2).
Whatever I try the Problem persists.
Working for me on Windows 10. What’s your OS? Can you use Help > About > Copy Debug Info and paste the text here?

Try this, especially safe mode: Troubleshooting - Anki Manual
Please close Anki, then open it in safe mode by holding down the Shift key while starting Anki. Keep holding Shift down until the on-screen message informs you that Anki has started in safe mode.
The issue still persists in Safe mode.
Observe the error while clicking on microphone
Seems like a headset, windows or driver issue, not Anki
what is circled in red are outputs, meaning they emit sound outwards hence the name speakers

Downgrading to 25.02.7 resolved the issue
Help！
I am facing the same trouble that I can’t record own voice in edit section of cards by the last edition ANKI Version 25.07.5 (7172b2d2) in macOS 12.7.6. My headset is working well to record and receive audio in other apps.
Failure information:
“Unable to record. Please ensure a microphone is connected, and Anki has permission to use the microphone. If other programs are using your microphone, closing them may help.
Original error: ’NoneType’ object has no attribute 'readyRead’ ”
Downgrading to 25.02.7 resolved the same issue as well. Thank you.
Help!
I’m having the same issue where I can’t record my voice in the card editing section of Anki version 25.07.5 (7172b2d2) on macOS 12.7.6. My headset works fine for recording and audio in other apps.
Error message:
“Unable to record. Please make sure a microphone is connected and Anki has permission to access it. Closing any other apps that might be using the microphone could help.
Original error: ‘NoneType’ object has no attribute 'readyRead’.
For everyone still reporting this –
Not much is going to happen until someone steps up and helps with this request from the developer.
