Internal Speakers Not Working After RAM Upgrade

(A2116)

Did a ram upgrade from 8GB to 32GB but now there’s no boot chime or sound coming from both internal speakers. Headphone jack works with sound. I have also tried a older iMac left speaker that was lying around. Tested with the screen off but still no chime.

I tried SMC and NVRAM/PRAM resets. Prehaps I wasn’t doing it correctly(?) (I don’t have access to it at the moment.)

What is going on?
