Recently I got a Mayflower Electronics Objective2 dac/amp unit. There is a strange problem whenever I launch SCE - about a 1 minute delay before the main menu shows up. Sound and everything still works fine except for that annoying delay. Also when I am in the garage and try to drive, there is also a lengthy delay. As well as when I exit back to the main menu the same problem. This happens in GTR2 and Formula Truck. Does SCE support USB audio or is it something wrong with my setup?
