I believe this is a software issue. Not a major one. I am currently using Roku OS ver: 13.1.4 Build:1512-CT on a 55" onn. RokuTV model: 100012586. Hardware: G813X Serial: X01200LA08JA Same issue on past versions. When the RokuTV goes to sleep it tells the soundbar to sleep. When RokuTV wakes it does not tell the soundbar to wake, no wake signal. I have to power off RokuTV and power on in order to use my soundbar again otherwise it just sees the soundbar as disconnected. Thank you.
