How about this (see images),
Option 1
----------
This way your TV will still be viewable from the chair, but surround effects will be only for the seating on Sofa. If wiring etc is a problem just swap places between the sofa and TV(along with the speakers).
Option 2
---------
A better option in my opinion, you can even move the sofa backwards(from what is shown) along the surround speakers, even beyond the pillar and see the practicality and effects.
Also a lot depends on your wiring and other furniture setup and if you can redo them and ofcourse the room size.
