Is there any fix for commercials being louder the other shows?
volume of the commericals compared to the programming is done by the broadcaster or cable provider not comcast. you would need to contact the local channel's broadcast engineer if local, or the help web page for the cable 'channel' (for example ESPN.com for ESPN).

Cable companies are required to prevent this, just as broadcast stations are. See https://www.fcc.gov/media/policy/loud-commercials, which says the rules apply to:
... TV stations, cable operators, satellite TV providers or other multichannel video program distributors ...
Also see "Filing a Complaint about Loud Commercials" on that page.
We pay our bill to Comcast. Therefore, the buck stops with them. I have the same issue and it is getting old. You own it Comcast, it is your responsibility. Fix it.
