The problem is the broadcast source, not anything in your house. Whether it's satellite or cable they both get their programming from various broadcasters and they set the volume. Same thing with that very annoying audio/picture sync issue with a lot of HD programs. Drives me nuts sometimes but without spending several hundred on a hardware audio delay device, nothing can be done about it and believe me I've tried.
Last year I finally got a Directv DVR and now I pause everything and go do something else for about 10 minutes and then come back and start watching the show. Once it has some lead time you can fast forward through the commercials in 30 second increments. They won't let you just skip them but the fast forward is quick and works great. It's a dual tuner HD one so even when I'm skipping through a live show, I can record another one so when I'm ready to watch it, I skip through those commercials too. Best TV gadget I ever got, highly recommended.
Too bad what happened to Billy Mays but I sure was getting sick of him. No more and I get to skip the Shamwow guy and all the others too. And, don't even get me started about how tired I am about good ole "Smilin' Bob". He makes me want to change my name. Anybody outside the US who doesn't know who I'm talking about, trust me you don't want to know.
