Ah, that's better. So you are getting sound to the TV, but the Comcast DVR remote doe not control the Panasonic's volume.
There are one or two things you'll need to do.
1. Have you programmed the Comcast remote to control a Panasonic TV? If so, can you turn the TV on and off using the Comcast remote? If not, you need to program it for a Panasonic TV. The Panasonic TV code is usually 0250.
2. If the Comcast remote still does not control the Panasonic's volume, then you have to re-configure the Comcast remote's Volume Lock/Volume Unlock function. Usually the default on their remote is set to control the DVR's volume, so if you want to control the TV's volume then you have to program it to do so.
These procedures are detailed in the user manual for your Comcast remote. If you don't have the manual, you can download it from Comcast's website.
If you need more help on the Comcast remote, you have to tell us which one you have. They have different ones in different areas, but the most common one around here is the silver 3-Device On Demand remote.
And tell us what brand and model your Comcast DVR is.
