Right, but the right is not absolute. A church is still subject to zoning laws. You can't decide to have the church of Abraham and Isaac and sacrifice a child unless the voice of God calls you off, etc. Yet none of that is written into the 1st amendment. We, as a society, agree it's not reasonable to hold knives to the throats of children or to build buildings in the island of an interstate.
There are lawsuits over noise ordinances for the Call to Prayer for mosques. Reasonable people can differ on where that level of intrusion into the interest of religion and the interest of people in their homes to be free from excessive noise is drawn. The 1st doesn't spell it out, we as a society have to apply some level judgement. However I think few people would agree I could set up concert level sound systems on my roof and damage the hearing of my neighbors with a Call to Prayer (or church bells) and be protected by the 1st. The rule may end up being relatively arbitrary number selected from a reasonable range, ie XX decibels is the max allowed...just like lead in water, etc. The standard will never be zero.
Dabble in semantics all you want, but there just is no way to explain away the wording: "...shall not be infringed". That means what it says!
