My Roku Streaming stick+ is hooked up to my tv and my tv is hooked up via optical to my soundbar. it has been working for years but this morning the sound wasn't working. I did a test of the soundbar and it is still functioning, the roku remote is still able to control the volume but still no sound. I tried doing a reboot of all the devices and still no luck. the only thing that I can think of that changed is it looks like the Roku did a software update late last night. any thoughts on how I can get my Sound back?
