I see.
I never really bothered to monkey around with opus to be fair, but that's only 'cause opus was born as a low-bitrate speech-optimized codec which has been extended to support other profiles for general contents encoding and because of that, its adoption has never been very widespread for general purpose contents and therefore many devices don't officially support it. For this very reason, I've been using AAC to encode audio files in lossy. It's pretty much the same reason why, whenever I gotta keep an audio file lossless, I still keep the original PCM in .wav instead of re-encoding it to FLAC: the megabytes it saves are negligible compared to the fact that almost nothing will play it.
