This is due to an update of the FireStick from Amazon. I was able to fix this by doing the following, unfortunately you cannot keep your existing build.
Uninstall Kodi. Then download this version of Kodi apk, kodi-20201031-3dfcc21e-aftv4k-armeabi-v7a.apk from the site

This is a special build of Kodi 18.9 for FireStick.
After installing, go to System->Audio (in Expert Mode) and change the settings as below:
Audio Passthrough: Enable
Passthrough Output Device: AudioTrack(RAW) .... This is the important bit.
Dolby Digital (AC3) capable receiver: Enable
Enable Dolby Digital (AC3) Transcoding: Enable
Dolby Digital Plus (E-AC3) capable receiver: Enable
Leave all the rest of Audio settings to DEFAULT
That's it. Now you will get DD+ in yout AV receiver and also ATMOS from Netflix if you have Premium subscription.
