After reinstalling Logitech Media Sever I thought I had the random loud static hiss issue fixed. I played various resolutions both upsampled and not, for several hours the last few nights w/out issue. USB sounding great. I turn the system on tonight and the first thing out of it is my old friend loud static hiss. Turn off the dac, wait 5 seconds, turn on the dac and its been playing fine for an hour. So very frustrating being unable reproduce and therefore troubleshoot this! I don't see how something can work perfectly for hours and then without making any changes -poof-. Ha it just happened again- It knows I'm trying to banish it from the house! I'd hate to simply have to abandon piCorePlayer because I really do think its a great program! Any ideas?
