I, and many others have the same problem:
Despite claims to the contrary, this system doesn't support sound coming out of cable boxes/DVR's, gaming systems, digital devices, etc.
You have to run those devices into your TV; and, run the TV Audio-out into the Sony system. If you have an HDTV, you will get surround sound.
However, the lousy power, muddy sound, limited inputs, etc. make this a system to stay away from. I really regret having purchased mine.

Yes, the Sony DAV-TZ140 DVD Player Home Theater System has audio input jacks (red and white). You can connect the audio output of the Cable Box to it and get the sound.
