Got a tech question for Sound & Vision? Email us at AskSandV@gmail.com Q I have a 7.1 system with an Integra AV receiver and I use a cable box for TV. When I switch to the Netflix app on my Sony TV, the receiver doesn’t switch to ARC; it stays on HDMI and I get TV audio instead of Netflix. Sometimes, powering down everything works to restore the connection, but the issue soon returns. Any thoughts on this? Thank you.
