I’ve noticed this as well, but I was having trouble articulating it. I believe my situation should align with yours.

1. Card is created with audio (sound.mp3) on Anki Desktop.
2. Sync on Desktop.
3. Sync on AnkiMobile.
4. On desktop, I open the file in MP3Gain to raise the volume of the mp3 without re-encoding.
5. Sync on Desktop.
6. Sync on AnkiMobile.

Result: Anki Desktop has a louder sound.mp3 than AnkiMobile because the change didn’t come over.

In this example, the name and file size of sound.mp3 wouldn’t change, but its content (volume) would.
