Solved! How do I get my fire stick to produce sound!!! I’ve tried everything it was just working earlier and now it’s not

First of all, does the HDMI port the firestick is plugged into say DVI or Monitor or PC? If so then this port has no audio through the HDMI port.

Surround systems are hooked up via 1 of 2 methods.
Method 1 - TV is output only:
Equipment is plugged into surround sound receiver via HDMI, surround receiver then outputs video via HDMI
For this setup you need to plug firestick into surround receiver.

Method 2 - Audio out to Receiver.
Equipment plugged into TV HDMI ports, then TV outputs audio via either optical toslink connection or RCA (older white/red plug cable) to audio input on receiver.
For this setup, firestick should be plugged into normal HDMI port on TV, and tv should already be configured to output all audio to external source.

Additionally i found this on google "If your device is connected to an AV receiver, make sure the receiver is on. From the Home screen, go to Settings > Display & Sounds > Dolby Digital Output and make sure Dolby Digital Plus is set to OFF. Unplug and reconnect the HDMI cable connecting Fire TV device to your TV"

Hopefully something here is a solution to your problem.
