Signa S2 Soundbar extremely slow to start up

Using my Harmony 665 to turn my activities on and it takes almost 9 seconds for my Signa S2 to power up and turn to the correct input! Is there anyway to speed this thing up. May seem trivial but when your tv has been on for about 7 seconds without and volume it's annoying! Using just an optical cable so it's not like it has to go through several steps. The sound bar powers up and 3 lights stay lit until it eventually turns to two lights and sound starts. Never had a Polk product before so not sure if this is just a manufacturer quirk or it can be adjusted. Thanks
