If it's still under warranty - return it to where you bought it - they'll either replace it or send it away to be repaired (either way it will be free of charge). If it's out of warranty either take it to a repair shop or the place where you bought it - either way you'll be charged for the repair.
This was most likely a faulty installation. I would call the company that installed the product to be sure. They should be able to fix any of the problems you are having with it.
It depends on what happens because the product is faulty. If you are selling a computer that is faulty because the space bar sticks sometime, then that would be OK. BUT, if you were selling a computer that will explode killing everyone in a 100 yard radius, then this is not OK. Is the product dangerous? If not, then it should be OK to sell, as long as you tell the buyer what is wrong with it and don't try to defraud your buyer.
To start a complaint procedure against a faulty product, you typically reach out to the retailer or manufacturer where you purchased the product. Provide details of the issue, including proof of purchase, photos of the fault, and any relevant documentation. Follow their complaint process, which may involve returning the product for a refund, exchange, or repair. If needed, you can also escalate the complaint to consumer protection agencies or small claims court.

Answer If you purchase a faulty product, take it back within the time limit that the store allows for returns. Most stores don't even bother to check items that are returned for defaults, they either give you your money back or exchange the product in question.
I am not sure if I understand your question but your mic should work immediately after it is plugged in with no additional set up required. If it does not then you may have received a faulty product and you should seek a refund and/or contact the manufacturer.
yes under the consumer protection act.
If the product is/was clearly faulty at the time it was delivered, you should be able to recover your sales price or at least a future credit. HOWEVER - if you accepted the product and only discovered that it was unsatisfactory hours or days later, you are out of luck.
No, you need to go after the manufacturer of the product.
depends what you mean, insurance will pay for a fire from an faulty electrical system, the insurance company will not pay for the faulty product itself only the resulting damage.
