After exhaustive troubleshooting, I’ve narrowed the issue down to the 3.5mm Line Out from my Optoma UHZ50 being the culprit.
Setup: Optoma UHZ50 Projector sending audio to Sonos Amp via 3.5mm “Audio Out”. The wire is one-sided on the UHZ50 side, then has a red and black end which plug into my Sonos Amp. My Amp powers to Definitive Tech DI-8R Ceiling Speakers.
The issue: One of the two speakers is very low, static, and simply sounds bad. I tried troubleshooting everything - new speaker wire, different banana plugs, even swapped the speaker (I have 4 and 2 are in box) and even tried a different Sonos Amp (I have 2, one is still in box). Nothing fixed the issue, so the only thing left to try was replacing the 3.5mm cable, so I went ahead and swapped that (I also have two of those) and the issue persists, but if I flip the Red / Black the opposite speaker has the problem. Basically the “Left” speaker out on the Amp is the problem when I have the “Red input in the red plug and the black input in the black plug” but if I flip the two (red into black, black into red) then the “Right” speaker has the issue.
Therefore, my issue is that the 3.5mm Audio Out Line from the UHZ50 is only sending clear audio to one channel on my Sonos Amp. I tried looking at the audio settings on the projector but no dice.
Am I missing some kind of obvious issue with 3.5mm Audio Out lines into Amps that’s causing this? Could me projector be defective? Is there anything left to try on the Sonos side?
Has anyone here had success sending Audio to their Sonos Amp via 3.5mm Audio Out?
Thanks in advance.
