[PlanetCCRMA] Major problem / confusion

[Julius Smith]

I too could not get JACK to work on the built-in Intel audio CODEC 
(after upgrading F12 to F14, both 64-bit) until I changed Duplex to 
Output-only in JACK setup, and I too had only a physical output 
connection (for a pair of headphones).  My motherboard is a year-old 
ASUS P7P55D-E Premium. - jos
