I have multiple Roku 3 players, they are in different rooms. Have always been able to plug in ear phones for private listening until recently. Yes have tried all the suggestions posted and the chances of ALL my remotes wearing out at once is very unlikely. I plug into the earphone jack, the TV volume goes off but no sound through the earphones. It also freezes the remote. Will not change channels or back out to main menu. Have to unplug unit, pull batteries from remote and restart and re "pair". everything. There must have been a change in the updates to cause this. It has always worked before and now doesn't work on any.
