I have an insignia NS-24D420NA16. My sound gradually fades away on both HDMI channels using the satellite box and Roku.
I tested the satellite box on another TV and it works fine.
If I turn the TV off then on again, it works for a minute, then fades to zero again.
I have no other devices hooked up.

Welcome to Community@Insignia!
If you haven't already done so, I would recommend power-cycling your TV by turning it off and unplugging it for several minutes. This should serve to reset the TV hardware. If the problem persists,
Since the volume change can also be related to errant signals sent by the remote control, I recommend resetting your remote by removing the batteries and pressing all of its buttons, then installing new batteries. This should resolve any issues with the remote control.
You may also wish to reset the TV to defaults. You can find instructions for this process in the User Guide beginning on page 65.
I hope this helps.

Okay, I power cycled the TV
I changed the batteries in the remote and pressed all the buttons
I reset the setting on the tv to restore default settings
I turned the TV On and the volume was fine for a few minutes, then faded to zero as usual
As it fades, the sound gets muffled before it's gone completely
This happens on both HDMI inputs
It happens on the satellite box and the Roku stick
There are no devices in between
The picture is fine
