Just downloaded 18 and when I try to play files it sounds like crap compared to any of the previous versions I have had (been with jriver since version 8 - it is the best). I am currently running 14 and it sounds great. I tried to make all the sound settings and DSP settings exactly the same but it still will not play properly. Do I need to uninstall 14 to run 18? I am just running onboard sound with Direct sound nothing fancy but that is what I have always used without issue. I am running Win7 64bit. If I can't get this sound situation fixed up then I might request a refund on this new version. Any help would be appreciated.
