Running your software on imac 27 inch with win8 installed via bootcamp. Modified sound settings to stereo and 16 bit to get server to run, then set to PCM output. ON ps3 selected Steram what you hear stream option. streaming commenced sucessfully However noted consistent and regular pauses in playback. Very similar setup using foobar and UPNP server to PS3 on another Win PC does not expiernce same pausing problem with PCM files? Will need to investigate further have you any ideas?
