It was quite a while ago, and I can’t remember every detail, but in general I first prepared a tab-separated text file for uploading. The sound tags [sound:xx.mp3] are all included in the text file. After importing it, I copied the mp3’s into the media folder. However, these steps can’t reproduce the problem.
I was thinking what might cause the problem. I recently downgraded Anki from 2.1.55 to 2.1.54, but I couldn’t recall if that import was done with 2.1.55 or 2.1.54. Could this be the problem?
All of the notes play all audios correctly in the Linux application, while the iPad app mismatches the new audios, either they’re on new notes or those notes updated in this import. Since it was quite a large import and the issue was not reproduced, I’m wondering if there’s a one-shot solution.
The default CSV importer changed after the 2.1.54 release. Can you reproduce the issue after switching back to the pre-release version? When you check one of the notes with the incorrect audio on AnkiMobile, presumably the filename in the field is the same as on the computer version? That implies that the actual file content is different, which should not be possible.
On iPad, Desktop, and Web, the fields all show the same sound label. But on both iPad and AnkiWeb, it plays a another audio (the one played is the same on these two and don’t change). I checked the audio file under this name on my media folder, it’s correct. So somehow the names of newly-added medias on the cloud are misaligned?
