    In a surround setup, the tv is used only for video.

    Your thread is titled "low sound from surround setup", but you don't have any of the stuff you mentioned, connected for surround. The best you'll get with the red and white audio cables, is Pro Logic (simulated surround). You have to use digital connections (digital coax or optical), to get 5.1 surround. With cable tv, the only channels that broadcast in surround, are the "Premium" movie channels (HBO, Starz, etc.), some PPV channels and HD channels. You'll need to run a digital coax or optical cable from the cable box, to the receiver (for audio). You may need to assign the input you use, to the tv/DBS. Your manual will tell you how. You'll also need to go into the setup menus, for your cable box, and make sure it's set to output digital audio

    I'm not familiar with Xbox. If it has digital output for audio, I'd use it too, instead of red and white cables.

    If you want HD channels and/or "Premium" movie channels, in 5.1 surround, you MUST use the optical output from cable box. All other channels will just be Pro Logic, which works fine, for regular channels.
    Same with Xbox..........if you have games that are in 5.1 surround, and you want to hear them that way, you must use the optical output, instead of the red and white cables. If you don't have games that are surround, don't worry about using the optical, from the Xbox.

    There are digital optical selector switches, like this one, that allows you to hookup more than one optical source, to just one input:

    Don't know about the "Y" adapters. Never used one that way (5.1 surround). I've only used them with stereo.

    In your case, the HDMI is good for video only, since receiver doesn't have it.
