Input routing incorrect in ProTools HD when 2x6 module installed in primary slot

There is a known issue with the input routing in ProTools HD if you install a 2x6 module in the primary slot of a Symphony I/O MkII and any other I/O module in the secondary slot and use it in ProTools HD mode.

Solution: If you are using a 2x6 module in combination with another I/O module in a Symphony I/O MkII in ProTools HD mode, make sure you install the 2x6 module in the secondary slot and the other module in the primary slot.
