Sounds like you got your TV installed. Congratulations.
To figure out why the audio isn't working properly I recommend the following trouble shooting.
Try a different TV. As long as you're using the same cable and connections this will tell you if it's the TV or something else. Sounds like you want to eliminate the TV as the problem, so I'd start with this then replace the cable and finally the audio source to narrow it down.
Good luck.

As I am watching TV on my 42" Panasonic Plasma,th42px500, the sound seems to get louder and softer without me adjusting anything. No surround sound set up, just the tv speakers. Cable TW 8300HD, with a component connection. Is it the TV or the cable box?
