A real missing-library case, from a working WAV control to successful M4A import, with four original screenshots and the file-picker workaround that mattered.

440 Hz synthetic tone. Start at a comfortable device volume.

No autoplay. Import, listening and export are separate checks.
What was actually checked

Operator-assisted Windows import of both controls, FFmpeg missing and detected status, and the successful M4A retry. Four original screenshots document the case. The samples were also inspected and decoded with a separate command-line FFmpeg build.

Not verified: audible playback in Audacity, exports, private recordings, other operating systems or every application version. See the exact test conditions.

OUR EDITORIAL RULE

Useful steps.
Visible limits.
