I used the same settings that I use for my CF Sabers: Right click the driver letter for the SD card, select Format, choose FAT32, Default allocation size, quick format (also tried full format).
I have also tried FAT32, various allocation sizes, quick format, full format, and multiple SD cards. None of them have solved the sounds being truncated.
I don't know what else to try. My ahsoka cf8 saber that I just setup with this same sound font and other fonts with clash-quote files plays them perfectly every time.
