Please help!!! All of a sudden the sound in all the apps have stopped working (Hulu, Netflix, YouTube, prime, everything!). There are still menu sounds (the clicking, etc) but once you go into an app it’s silent. Our tv doesn’t not have the PCM option, but we have been using it for 2 weeks and have not had any issues until today. Not sure what to do. Please help!
Have you tried restarting the device? Settings > System > System restart (This is menu path for a separate Roku device. I don't know if it would be the same for a TV with Roku built in, but it ought to be fairly similar.)
These things are just little special purpose computers. Like their big brothers sometimes you just need to clear things out by restarting them.

Same issue here. Brand new roku hooked directly to my 2 month old Samsung soundbar via its HDMI input - if I fast forward a video and when it starts playing again, there is no sound. This is across all apps - at this point no sound will play on any video no matter the app. I can however still hear UI/system noises, clicks etc. if I reboot the roku it all works again, then boom the problem comes back as soon as I FF or RW.
if I set my audio on the roku itself to STEREO only, everything works. On Auto, the problem above rears it’s ugly head.
