I mean playback from an HD attached to a Mini via FWire 800, the Mini's (10.8.6) USB output stopped playing a week ago, this started maybe with 155 or 156, but still plays over my LAN to the PSA DAC Bridge. A month ago eLyric USB also stopped so I assume it is not a JR Mac issue unless I disabled something accidentally.
P music and Decibel continue to run on USB. Does that explain my problem ? Will do the checks you suggest, thks.
