custom playsound bug

Hello I installed a resource pack with custom sounds the resource pack is on 1.12.2 and Im using 1.13.2. {{        "custom.shotgun": { "sounds": [ "custom/shotgun" ] },        "custom.re": { "sounds": [ "custom/re" ] },        "custom.zeusX": { "sounds": [ "custom/zeusX" ] },       "custom.zeus": { "sounds": [ "custom/zeus" ] }} Code in sounds.json sounds have 1,55MB ~50kb, 132kb and 20kb. Only the longest crash in 20 second or starting another sound or lag my game on few seconds and return without sound.. How can I fix that? Will this fixed in newest snapshot?
