Hi, I'm a newbie to this forum and to home diy projects. I'm trying to run power and hdmi cables behind drywall and around the fireplace. I used stud finders to find the studs; however, after I removed the drywall for the wall plate, I ran into what seems like solid wood behind it. I really wasn't expecting this and have no idea what to do. I'm not sure if I should cut through or what. I only have a drill, so I'm not super jazzed about buying another tool to cut through the wood if it's not going to help.
Anyway, if anyone has any ideas, I'm all ears. Thanks in advance for any help.
