Using Vizio Tv as a computer monitor with a Samsung soundbar connected via arc/cec . I often mute the soundbar, and it automatically shuts itself off after a while, the problem being when I turn the soundbar back on manually I lose the hdmi signal to the computer "comes back instantly if I shut the soundbar back off otherwise I got to restart the computer. simply turning the tv off/on does not work. I could easily switch to an optic or 3.5mm connection, but I do rather enjoy the benefits of the Arc connection.
