Connect roku to switch box to surround system

If the picture is OK then check your sound cables, red and white if analog, or swap out the HDMI cable with one that you know works.
Also, on the SETTINGS screen make sure your audio is set to stereo not surround sound.

You will need the Audio input to come from your tv to the surround system (path= Satellite Receiver >Television>Surround System)

connecting your surround sound system is not complicated.things you may need:OLDER STEREO SURROUND SOUND:analog red, white, and yellow cable connectorsHDMIaudio fiber opticsif you bought your stuff new from electronics store,then it would be easier.all you need is HDMI cables (mostly)depending where your inputs and outputs go, you must know the rule. OUT-TO-IN. that means if you are using a cable box, dvd, bluray, playstation, or xbox. everything in these electronic devices are OUT. then connect them to the IN ports of your surround sound. at the back of your surround sound there will be connections saying IN-dvd, IN-dvr etc. connect your OUT DEVICES.
NOTE: YOU MUST KNOW WHAT ARE YOUR CONNECTIONS, LIKE DVD-IN OR DVR-IN CU'Z YOU WILL USE YOUR REMOTE TO CHOSE WHICH CONNECTIONS YOU WANT TO USE.
now from your surround sound to your tv.the same ruleout to in of your tv. You should look for HDMI port that is saying OUT. you will connect your HDMI cable from there connecting to your IN of your tv. remember which port you plugged the HDMI cable as you will switch to that particular input. it will say at the back of your tv in-1, in-2, in-3 or as much as the manufacturer want to have in there product.
connecting your speakers.you must remember the color code.if you chose red as positive, all the red wire must be positive.colour may be different but same idea. if you have sub-woofer it will be an analog cable you will only use single cable. At the back of your surround sound there's a connection saying sub-woofer out.
now selecting your inputs.turn on your tv and stereo.newer tvs and stereos are smart they can configure there system which is turned on.
anyways if you will do it manually, you must select from the remote what is the connected input. (input 1, input 2 etc.) if you found the right input, do the players (dvr, cable box, dvd, bluray, playstation, xbox etc) turn them all on and select from your stereo remote control.note all the inputs you selected.

Are you using a cable or satellite box? If so you can connect the audio out jacks to the Surround Sound instead of the TV.

Hi, and yes there is hope, there's a saying that when something is tedious and or boring to read "it reads like stereo instructions ".The first thing to make sure of is you have a rather stiff connecting cable called a "TOSLINK" cable this has squarish ends and plugs into the "DIGITAL AUDIO OUTPUT" of the x-box 360 and then plug the other end into whichever input your using for the x-box. A dead giveaway to the jack to use on x-box is that it may actually be lit up red while playing. it also may be labeled "PCM/LPCM" versus digital audio. Anyway that should get you your surround sound on your stereo. Thanks for choosing FixYa, Let us know if there's anything else we can help with,and good luck, Prodzilla

The tv must have a stand alone audio output that you would connect the audio composite cables to going to the aux or audio input of the surround sound system. You may need to switch the surround sound system to aux mode or av input 1 or 2 and etc. If you are connecting a cable box or satellite tv box to this television instead of connecting the audio composite cables between it and the tv, connec them between it and the stereo surround sound system.

You may have to set the TV output to stereo or matrix out. Also if the stations are not in stereo or surround it will not play in surround.
If you are connecting to a cable or satellite box and you are just using the coaxial input to the TV you may not get stereo. Some cable companies only send mono signal through the coax and you need to connect the tv to the box using component cables and the R and L audio connections.
There may also be settings in the receiver that you have to adjust to get surround from the TV.
You could connect the audio out directly to the receiver instead of the TV and just use the receiver for TV sound.

Hope this helps

On your Sagem TV you should have two RCA ouputs (red and white connection usually marked ouput) ) Connect these to the input on the surround system using the interlink cable.

You should then be able to hear the sound from the TV by changing the SOURCE on the home cinema remote.

Better still if you have a digital out on your TV use that instead.

Sounds like it's just in 2 channel stereo mode, only 2 speakers working out of 5 and a sub, look for a selector switch for switching to 5.1 surround, as far as the no video problem try replacing the cable for the video connection. 

Since you have a surround sound system, you probably should just bypass the TV's audio.

Connect the red/white plugs from your digital cable box to one of the inputs on your surround sound system but not the Phono input unless the Phono input lists something aside from Phono, like Aux/Phono or CD/Phono.

Connect the S-Video or composite (yellow) video plug from your digital cable box directly to the S-Video or composite (yellow) video jack on your TV.

If your digital cable box does not have a S-Video (4 pins and flat rectangular hole) or Composite (yellow RCA jack) jack and only has the screw/push-on type cable with the pin in it, then leave the remaining connections as-is.

Now switch your surround sound system to the input you connected the red and white plugs to and turn on your TV. You should see picture from the TV, but hear audio from the surround sound system.
