I'm also having the same problem on my Roku TV. SInce the most recent update, when I watch certain channels it will automatically switch to Spanish, even though the TV is set to English. I can toggle the SAP settings to "Off" then back to "English", but its getting annoying having to do this constantly. It will also start "narration voice-over" on other channels and I have to toggle the SAP settings again to get them to stop. This only happens with I watch Live TV stations, not when I am streaming.
Is there a fix for this coming?
