I've been lurking on this forum for quite sometime, but finally registered! The suggestions I've found in old threads have been very helpful in getting me to the point where I'm at now. I now have a few specific questions for which I haven't been able to find answers online.
We have our TV mounted over our fireplace/mantel. It has worked well for us, but my wife is now pushing me to finally finish the project and move the wires behind the wall. I need to run the center channel speaker wire, HDMI cables, and power cable horizontally from a recessed box to an adjacent stud bay and down to the wall plates next to the fireplace. I cut away some of the drywall to see what I was up against in terms of getting past/through the fireplaces framing. I will post pictures below.
1. Will notching the studs be a problem in this area? There are two studs that run vertically along the right side of the fireplace and a 4x4 a few inches to the right of the studs. If it is possible to notch the studs and 4x4, that leads me to question #2.
2. In the study bay I was hoping to use to run the cables down to the yet-to-be-installed wall plates, I discovered a pipe that runs vertically in the wall. It seems to be inline with the gas valve next to the fireplace (it runs about where the speaker cable is hanging in the picture below). Assuming it is a gas pipe (not sure why the pipe runs vertically towards the second floor of the house), can I run the cables in this space next to the pipe?
3. Ideally, I would also like to run power behind the wall. The recessed box has a space for a duplex outlet and I was told I can run romex to the box as long as it is in a separate conduit. Can I run the romex horizontally across the same bay as the pipe? I have to cross over two more studs to get to power.
Any guidance would be greatly appreciated.
