Used to work but not now Win 10

Microsoft Windows 10 Professional (x64) Build 19044.1387 (21H2)
Audacity ver: 3.1.2
Realtek Driver Version: 6.0.1.7544


Hi All,
I’m quite new to Audacity and it has worked well recording audio from videos on the internet, however over the last couple of days it simply will not record anything I play from the internet or my laptop music. I have downloaded the Zip and looked at the contents.
it is using: Selected recording device: 18 - Stereo Mix (Realtek High Definition Audio).
The log shows:
11:17:06: Audacity 3.1.2
11:17:06: sqlite3 message: (1) no such table: project in “SELECT 1 FROM project LIMIT 1;”
11:17:06: Error: Failed to load shared library ‘avformat-58.dll’ (error 126: The specified module could not be found.)

11:21:08: Report generated to: C:\Users\AppData\Local\Temp\Audacity_dbgrpt-6300-20211129T111945.zip

So a lot of modules that cannot be found :frowning: So anyone got any suggestions as to what I should do?

Many thanks.

Those errors are unrelated to recording. The main “issue” there is that you don’t have the optional FFmpeg for Audacity installed. FFmpeg adds support for file types that Audacity does not support natively, it does not affect any other operations in Audacity.


The “Stereo Mix” feature is a very old feature in Windows that is being phased out by Microsoft and sound card manufacturers. It has been replaced by a “loopback” feature in Windows “WASAPI” sound system. How to use “WASAPI loopback” is described here: Tutorial - Recording Computer Playback on Windows - Audacity Manual
