Trying to figure out a sound solution for a 6-foot wide stone fireplace with a TV mounted on it (something I hate, but…). There will be base cabinets and shelves on either side. Since there is zero chance I want to live with the built-in speakers, seems my choice is to either mount a soundbar below the TV, live with just left/right in-wall speakers on either side (WAF will not allow a center channel in the stone) and maybe some in-ceiling rears, or go entirely in-ceiling - although it is a vaulted ceiling.

Any thoughts on the compromises between a soundbar, a phantom center channel, and in-ceiling mains? This will NOT be a primary movie viewing location, but will be used for music as well.
