Either unplug dish from tv or use the antenna side which is HD and program channels and see if volume the same, if not and is OK then it's your Dish bring your sound down or audio cables bad.

This likely has a bad main board.

That white line (usually jagged) is actuallly part of the transmitted picture. However, you are not intended to see it because it is located in what is known as the 5% overscan area. Your TVs today are more than just cable ready... they are a versital, technology filled multimedia display. You can see that line because the screen size or wide mode you are using is intended for 1080p/24 signals. You have 0% overscan with this screen size setting. This allows you to see ALL of the picture, including portions of the picture the broadcaster did not intend for you to see. You can change your screen size using the Wide feature in the Setup menu. See pg.62 of your user manual for details and descriptions of the various wide modes.

Unplug the TV from the wall. There must be something wrong with your circuit board. Call customer service for what to do to fix your TV or get a new one.

Go to your On-screen Menu, go to settings, select audio, then select LIP SYNC. You can then adjust the amount of shift to synchronize the pix and the audio.
