I have been having the same issue, and the problem just started one month ago. Yes, the sound does come back when I unplug/plug in the ROKU, but I should not have to do this EVERY DAY!!!!! If that is the case, why not add a power button so that we can turn the ROKU on and off to alleviate this issue? This is ridiculous. Up until this point, I've loved my ROKU service and converted all of my Amazon Sticks to the ROKU (5 Total). However, I'm starting to have second thoughts as I NEVER had this issue with my Amazon Stick and this ROKU sound issue is becoming a daily routine. Also, this is the second ROKU where I am experiencing issues. It's ridiculous and I am about to switch back to a different streaming service.
