Comment (by skirhir):

 Replying to [comment:1 TD-Linux]:
 > The output wav duration matches opusdec, so the bug is not in the
 conversion but that ffprobe does not take the start or end trimming into

 If conversion is correct, is there a way to convert to an untrimmed
 version by replacing the trimmed section with paddings or at least access
 the trimming information?

 I stumbled upon this when trying to sync audio from multiple webm sources,
 were the opus trimming seems to be used to sync the video and audio
 tracks, and I couldn't find a way to keep a time reference.
