Will this amplify the sound?
We have a Samsung smart TV but when we play video off of thumb drive we often max out the volume and still can't hear.
No. If you want great amplified sound , purchase a iLive product . Trust me . I own the iLive, for $96.00. Then purchased LG for $300.00. Then last but not least , the Vizio. The order that I placed these in is the recommended order.
