[Bug] Embedded lyrics not recognised in .opus and .m4a files

[Aditya137x]

Description

I have embedded lyrics using SongSync to many of my music files which are mostly .opus and .m4a.

To verify if the lyrics are embedded correctly I have used Gramophone and it is recognising, syncing and displaying the lyrics properly.

Steps to Reproduce

1. Download any song using YTDLnis
2. Embed lyrics to it using SongSync
3. The lyrics doesn't show up in the app.

Expected Behavior

Lyrics should be visible when I tap on lyrics button

If I download .Irc file from SongSync then lyrics shows up. But if I embed lyrics to file it doesn't

Same issue here with my opus songs. App didn't read embedded lyrics from them

Edit: my phone is Pixel 7a, Android version is 15, and the Symphony version is 2024.12.115 from Github.

Also, here are two sample files of charli xcx's 360. The former is encoded with libopus 1.3 using opensenc from opus-tools, while the latter is encoded with libopus 1.5 using FFmpeg. Both have the lyrics problem on the app.
