No sound or dialer after custom s4 root topic

Hi, i'm new to rooting and flashing. I recently rooted my phone using odin, and flashed a custom rom. I thought I did a backup of my original hardware but can't seem to get back to it. When using the custom rom, everything works except for sound or any apps that require sound, that includes the phone dialer so I can't recieve or make calls. I tried flashing new roms, I even unrooted and installed the stock s4 bell canada rom.
When the phone reboots, it'll say kernel is not seandroid enforcing, and from what I understand, that means that maybe my phone is still rooted??
Currently, i'm back to my stock s4 rom, but sound and phone still doesn't work. Please if anyone has any info on this it would be greatly appreciated.
Thanks
