Upon trying to change the disk cat to the old console version of cat with dog appended I realized that it would not play as in it was just silence. It knew the file was there otherwise it would just play standard cat but instead it was just silence. I figured it was too large a file size but in preparing the test resource pack I realized that the shorter audio file was actually larger in size (Bytes). So best I can say is that it is actually length, not size hindering it. Yes, the format is .ogg, See attached .mcpack file

Expected: Longer audio files will play

Observed: Longer Audio files won't play

Reproduce: using a resource pack replace an audio file (such as the record cat) with another audio file longer than 2:33 (in my case)

^{Note replaced audio files are This Glittering Band from Halo 2 Anniversary}

^{Updated pack for 1.18}
