Hi, same issue here, it was working perfectly yesterday but it stopped working today. My environment:
OS: Ubuntu 24.04.4 LTS
Install: AppImage
Cursor versions I tried: Cursor-2.4.37-x86_64.AppImage, Cursor-3.0.12-x86_64.AppImage and Cursor-3.2.21-x86_64.AppImage
Mic I tried: Laptop built-in and camera built-in
Language: English and Spanish
With all the AppImages I have the same symptoms, I click the voice button, I see the voice level moving, but no text appears in the chat.
I tested more AppImages from version 2.4.37 (6 from 12 intermediate versions) until 3.2.21 (that I downloaded today) and they all fail the same when before they used to work.
I checked both mics works with other applications, that I can capture audio, etc. The only app failing with the mic is Cursor.
Opening DevTools->Network I can see the same error in all of them:
URL: vscode-file://vscode-app/.../vs/workbench/contrib/composer/browser/voice/voice-processor.js
tatus: (failed) net::ERR_FILE_NOT_FOUND
I uploaded the screenshot of the only three entries that appeared during the voice recording using Cursor-3.2.21-x86_64.AppImage.
My Account is an enterprise team account. As I stated, Using AppImages, so no code changed in the Cursor installation, yesterday it was working, today it doesn’t with any of the previous AppImages that it used to work. All other Linux apps work fine with the mics.
