Q:
Left Surround output is 6dB too hot in Pro Tools 6.7
 
A:
This can occur in certain configurations in which the surround mixer gets split between chips on the HD Core and HD Accel cards. While Pro Tools 6.7cs2 fixes a similar issue, this issue can still occur in 6.7cs2 - 6.7cs8. This issue is resolved in Pro Tools 6.9. The workaround for 6.7 users is to use the 6.9 stereo and surround mixers.
