Audio Issue with UR816C

In the last day or so, my UR816C has basically lost output on the right main output. There is still signal there, but it’s coming out VERY softly and almost all high end. As if only the tweeter was getting signal. I swapped speakers, cables, and everything else I can think of. It SEEMS like the problem is with the output of the interface and not anything else. Audio output is completely normal from the headphone outs, and I was able to move my output to 1R and 1L and it works normally that way. The interface handles both Cubase and my normal PC audio output and the problem is there no matter what application everything is coming from. It’s worked fine the last few years up until a day or two ago. I’m HOPING that someone knows a simple fix. I can’t really afford to run out and buy a new interface right now…
