I found the cause of malfunction. My ADI-2 DAC does not accept certain settings in MC 32 which it did accept, the same settings, in MC 24! Namely: when both "exclusive access" and "integer mode" boxes are checked, there is a problem (stuttering sound) in the new version of JRiver, while all is fine with this setting in the old version. Interestingly, when either box is checked alone, the playback in the new version is fine. Please comment. Would it be good for sound quality to use both exclusive access and integer mode? If impossible to use both (as it is now), which one should I choose for sound quality (convenience is not important)?
