I had same issue last year on my high end home theater last year. I don't game on it usually so i'm not sure if it is the same this year for me but i'd guess probably. Last year it was one of the modes on my home theater that I switched and found something that worked but unfortunately I dont remember which exactly. I'd suggest messing with the different surround sound features on your Bose. If the commercial breaks are super loud but everything else isn't I dont think the ingame volume sliders will help you. The ingame pre sets maybe but I still don't think that will do anything. Did you try the 5.1/7.1 setting? that might work but I doubt it. The sound between commercials that's really loud is that coming from the middle speaker?
