[RPi3B+] No Composite Audio

So I finally got my 3PiA working with LibreElec, but it kept crashing as it was running out of memory. So I upgraded to a 3PiB+, and now LibreElec and Kodi run great, but I have no audio on composite!

I have the right cables (MicroCenter actually sells the specific ones for RPi), as I am successfully getting video on the yellow pin. I switched em around just to make sure they're not the "old camcorder" style, but no.

I already edited the config file, commenting distro and uncommenting distro_composite. I also added the necessary line to cmd video=Composite-1:720x480@60ie

I tested the enable analog audio line, but it doesn't seem to do anything. Googling actually led me to another thread on here explaining that's for people who want digital video with analog audio.

Are there any other fixes or settings I should be changing?

No luck with any of the settings listed. I tested the same cable on a different device just to confirm that there's nothing wrong with my TV itself on that composite input.

Ordered the recommended Adafruit composite cable from DigiKey just to be 100% sure. In the meantime I paired to my Bluetooth surround sound speakers, which is probably better than using TV speakers haha.
