If you're missing audio (like dialogue or environmental effects) in games or movies, make sure Upmix is turned off. Upmix is designed to simulate surround sound from stereo sources only, and having it on during true 5.1 or 7.1 content can scramble things a bit. 🔇
Some games automatically detect your Arena 9’s surround setup and send audio across all channels. If Upmix is still on, this can confuse the signal and cause certain sounds (like voices!) to vanish into the void. For the most accurate surround sound experience, keep Upmix off when enjoying native multi-channel content.
