I have been using JRiver for several years and today something unusual happened.
I was using build 76 of MC 25 and noticed that playing back stereo music did not sound right. The left channel was shifted to the center channel. I tried playing music through foobar 2000 and everything sounds fine. I played around with various settings in MC, trying to get the left channel back. I turned on room equalization and boosted the output to the left channel but that did not help at all. At some point I noticed that the center channel was also gone and only the right channel was playing music.
This evening I updated to build 80 and saw the same behavior. However when I played back a surround sound (5.1) music file, all the channels were header. After switching back to a stereo file, I find that the audio is back to using center and right channels.
Any suggestions on how to debug this further?
