Xbox works and runs fine, the audio works but there is no video. Audio is hooked up to surround sound and the video is hooked up to a hd tv

Are you using your TV for both Audio and video? Sounds like you are only wanting HD video and SS audio. If, so only send HD video signal to TV and keep SS Audio direct to speakers from SS receiver/ amp.

i think your problem is with cabling your surround sound is audio only and you wii is video and audio. i would hook up wii first and get it working first. dont plug the surround into the yellow jack on your audio video switch
good luck

i have the same system. all you have to do is when you connect your xbox 360, press the surround button on the remote and then use the arrow buttons to change it to dolby music pro2 or multi channel audio. same goes with any device you connect. hope it helps. In my case the xbox is connected to the Tv via HDMI and bluray player is connected to xbox via compoent cable

Have you seen the user guide?

The TV is intended to be an end point of the video, not a source of audio. Many TV's (monitors) don't have ANY audio, much less surround sound capability. Composite Video is theminimalist video connection for setup; Component video to the TV should suffice for viewing DVD's.

Is your TV the SOURCE of surround sound programming (via an antenna) or does the programming come from elsewhere like a Cable Box? THAT would be the source you need to tap for surround sound.

I dont wish to assume that when you say receiver, you mean sattelite or cable. Since you may be trying to hook this up to a surround sound reciever...

Let me also clarify, if this is the case, the receiver needs to be turned on AND the selection signal device set to TV or AUX wherever it is you've connected the TV.

Now by receiver, if you actually meant cable or sat box, then the Ext antena from that service connects to that units ANT IN.

Then from there on that unit ANT OUT to your TV SIGNAL IN.

If you want the external surround sound and have the connectors for this. Then you need to send them OUT to the Stereo/Surround receiver TV IN.

Now having said that and assuming that your TV does not have the Red and White Audio RCA connectors... Your Sat or Cable box does... You connect those to the surround sound Receiver Audio IN

Hopefully you'll find this useful.

If this has not answered the situation. Please feel free to come back and provide all components your working with. Surround reciever, Sat, cable, DVD, VCR whatever etc. etc... I'd be more than glad to help you through this


Good Luck

Hook your Xbox to tv via HDMI, then hook TV to reciever through digital optical or composite cables. If you try to get your picture through receiver first, you may get picture and sound but, sound may be delayed and picture might not be the best. Bettter to run through tv first then provide sound to receiver.

You should be able to hook it up with a component video cable. A component video cable is a cable that has 5 color coded RCA style ends that are Green/Blue/Red/White/Red. The Green, Blue and one of the Reds is for the video and delivers the signals needed to produce the HD picture and the White and the other Red is for the audio to provide you with stereo sound.

The Video cords will plug into the section labeled component video facing up and down and the audio will plug into the side by side section. So if you plug into Component input 2 then you would plug in the audio into the audio section of input 2.

If you have a separate surround sound system you can connect one of two ways.
1. Plug a separate Audio (red/white) cable from the Blu Ray to an available input on the surround sound.

or

2. Plug all inputs into the TV (as noted above) and then plug a separate Audio (red/white) cable from the tv labeled "Audio Out" to an available input on the surround sound system.

If your TV is HD, you should definitely be connecting the component video cables (green, blue and red) from the 360 to the TV (the 321 will not do video pass-thru from component cables). -Make sure you have a picture at this point. (TV switched to whichever input you connect the 360 to)
You can get an RCA extension cable for the audio portion (red and white) to connect to the 321 for audio. You could also connect an optical audio cable to the 321. An optical cable must be assigned from the system menu to work..
Let me know if this helps.

Check Your TV audio setup,many TV makers out there would like you to turn off the tv speakers in order to use the external speakers.

In short, the answer is: Hook up all three to each other. I have a Samsung DLP HDTV, and I was trying to hook up a Sony DAV-HDX500 home-theater system and a Comcast HD set-top box, but I found that the Sony user guide is helpful only for setting up the speakers. Most of what it had to say about HDMI and getting the TV sound or cable sound to go through the speaker system was wrong (or, at least, it didn't work for me). So, here's what I did. I connected Component video cables (Y/Pb/Pr out) from the Cable box to the TV (Y/Pb/Pr in), audio cables from the Cable box (audio out) to the Sony system ("SAT/Cable" audio in), and an HDMI cable from the Sony system (HDMI out) to the TV (HDMI in). This allows me to 1) watch DVDs with surround sound through the TV's HDMI source (when the "DVD" format is selected on the Sony system), 2) watch cable with surround sound through the TV's Component source (when the "SAT/Cable" format is selected on the Sony system), and 3) watch cable WITHOUT the surround sound, as I did before I ever had the Sony system. One item of note: When watching a non-HD channel with the surrond sound on, the audio is slightly out of synch with the video; thankfully, there's no such problem on HD channels. Anyway, I hope this helps. It drove me crazy for two days straight!
