Sorry, there was a problem. Please try again later.Try using the "TruVolume" feature. It's what's called a "volume leveler". It's turned on using the "TVOL" button on the remote. https://www.tvtechnology.com/opinions/srs-truvolume-debuts-in-vizio-products http://cdn.vizio.com/misc/KBImages/models/m21dh8/manual.pdf (page 11/13) It is also possible that the product is defective. Call Vizio support.
