Its not clear here wether > when I try to run both means audio signal (and signal ground) is connected between them or not What we need to know is that if both are run from the same PSU but NOT connected together in any way apart from the PSU 0v's are both still quiet. If they are its due to the audio signal and signal ground when connected together If they are not both quiet in the scenario the problem becomes more complex but possibly curable Jeff *Players:* SliMP3,Squeezebox3 x3,Receiver,SqueezePlayer,PiCorePlayer x3,Wandboard *Server:* LMS Version: 7.9.0 - 1475786002 on Centos 7 VM on ESXi 6 on Dell T320 *Plugins:* AutoRescan/BBCiPlayer/PowerSave/PowerSwitchIII/Squeezecloud *Remotes:* iPeng8/Orangesqueeze/PC/Jivelite *Music:* 383GB,1269 albums 17756 songs 4381 artists mostly FLACs *Want a webapp ?* See http://forums.slimdevices.com/showthread.php?104305-Webapp-for-LMS ------------------------------------------------------------------------ Jeff07971's Profile: http://forums.slimdevices.com/member.php?userid=49290 View this thread: http://forums.slimdevices.com/showthread.php?t=107557 _______________________________________________ diy mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/diy
