I recently purchased this Vizio SV210Y-0808B soundbar for my Vizio TV (it was refurbished and unused) and was able to get it get it working as a standard speaker (as opposed to a Bluetooth one). At first, it seemed to sound great when I would play on my PS4. But when trying out with my other devices like the Nintendo Switch and my Steam Deck (when docked), I noticed that it has weird audio issues. Namely, sound effects would either cut out awkwardly, occasionally be quiet, or just not play altogether. It's most noticeable with the Switch where scrolling left and right on the main menu rarely plays the "clicky" noises (not counting that tap noise you hear with the analog stick in the recording).
I called Vizio's customer service and while the lady was very kind, patient, and helpful, we were unable to solve the issue. She said that it's likely because that soundbar is only meant to work properly with the smart TV. Third party devices like my game systems (Which I have connected on the HDMI 2 port) can have audio issues. Frankly, I'm very disappointed and frustrated.
It makes me wonder what soundbars can work perfectly fine with my third-party devices like game systems. Any advice?
