Lost sound on dav3102 system

You don't mention the sound card(s) in the PC nor the method of connecting to the monitor. Some video cards have HDMI connections for audio and video out to a monitor and will not allow any other audio outputs to work. Regardless of sound source interface, check to be sure that the audio source is the one that is NOT part of your video card and is NOT set to output DIGITAL audio signals.
Once this is done, select the the "add-on" or "expansion slot" sound card (if it is the type that plus into a slot on your motherboard) or the "built-in to the motherboard" type (if the jacks are soldered directly to the motherboard) as the DEFAULT or ENABLED. Set to ANALOG output - NOT digital if a choice is offered. Connect the speakers. This should be via cable terminated with a stereo mini jack - NOT a special digital optical or coaxial cable / connector. Most modern PCs will have several mini-stereo jacks from which to choose - nearly all use the GREEN ringed jack for the FRONT (or main) left & right stereo speakers. Regardless, if yours has GREEN jack, you should use it - if none have a color code, look for markings that indicate either "speakers" ,"output", "front" or "L & R". If there are no indications, check your manual. Set your volume level on the lower side, play an audio source and adjust speaker volume and / or audio mixer settings in the system tray as needed.
Only one sound card will work in a PC. Make sure that all connections are made to the ENABLED card, otherwise no sounds will be heard. Digital output is primarily targeted to facilitate connections to external amplifier and speaker system - most often like those found in a Home Theater PC setting - or a monitor / TV connected by an HDMI cable.
I hope this helps & good luck!

I would Google the model number carefully for "problems" "no sound" and usually this set will display some kind of error code===it may even have a hard reset to try===service manuals are available on the net/web to allow you to see how the sound circuit is set up etc.

If you are playing a source that is Stereo such as FM Radio or a CD the sound will not use all 5.1 speakers unless you enable the correct Surround Mode. On the remote there is a button on the lower right of the remote that says SURROUND. You can toggle through the various surround modes with this button the mode you want is Dolby Pro Logic The Pro Logic mode uses the built-in circuit to steer the Left, Center, Right and Mono Surround channel audio signals and uses all five speakers to play both stereo and Dolby Pro Logic program source, such as TV and VCR. You can use this mode with any stereo program source (such as VCR/TV) to enjoy multi-channel sound experience.

If you have the users manual for the unit, go to the troubleshooting section or the section that explains how to set individual speaker levels and effects and reset the balance there. It sounds like somebody tried to set things in this way but maybe got a little confused and turned off the wrong selections. There should be a demo program built into the receiver that allows the listener to hear all of the different settings available with the different effects also. Hope this helps.

Check how you have the satellite cabled. I suspect that you have the video from the satellite to the TV but the audio cable going directly to the stereo. You probably have the DVD audio and video going directly to the TV. (I'm assuming you have the 32LA30rq and not the 32LA30rqd which has a built-in DVD and thus has the audio connection inside the TV.)

Since you don't mention which connection you are using for the DVD player and for the satellite, I will just mention the basics. If your DVD player is connected to one of the HDMI ports, that cable carries audio and video between the TV and the DVD player.

Devices that use component video cables use two separate cables. One cable with two sets of three RCA plugs carry the video; a second cable carries audio with 2 RCA plugs on each end. When you connect these, you do not have to connect the audio to the TV. (Similarly, a composite video connection can be modified for one line with the video signal going to the TV and the audio cable going to a speaker system.)

If my solution is correct, you may want to rearrange things. You can connect the satellite audio out to the TV audio in at the same location as you have the satellite video in. Then connect the TV's audio out (to the right of the component 2 in and above the coax audio out) to the stereo. Then switch the TV speakers off to use the stereo - Menu > Sound > Other Settings > Speaker On/Off. Then both devices will play either at the TV speakers or the stereo depending on the state of the TV speaker setting.

The manual is available here: http://tv.rca.com/product/manualdown.asp?modelnum=32LA30RQ .

I hope this helps.

please select the 5.1 option in the audio menu of the reciever.

Well you have a built in decoder/surround processor that will detect a signal with the surround sound info(dvd/sat.receiver/cable converter etc.) and will then process it to the different speakers on your system. In the absence of that signal it will process it as standard stereo sound(two front speakers). You may want to look in your receiver functions/menu for simulated surround.
Hope this will help.

A home theater system usually consists of a dolby digital stereo amplifier and 5 to 7 speakers.

Turn your stereo on and select the source that delivers video to the TV (DVD, VHS, Game, etc.). The video may be connected directly from the device to the TV, but the audio should connect to the stereo system (DVD, VHS, or other input). This way, the source audio is sent to the stereo and it provides the big sound to match the picture. Otherwise, you'd have to connect the source audio to the TV and let it's comparably tiny amplifier and speakers provide sound - that comes up short.

When playing a DVD, select the DVD input on the TV *and* the DVD input on the stereo. If you do not connect the audio to the DVD input on the stereo system, you'll have to connect to the TV, otherwise nothing will be heard.

connect stereo rca jacks behind tv labelled audio out then connect to any available input in home theater receiver

You don't say whether you're successfully getting sound out of your stereo or not. I'll assume for the moment you are. Still getting sound out the TV is perfectly normal - RCA plugs have no mechanism for automatically disconnecting the built in speakers (in this respect, they're different from a headphone socket). Solution should simply be to press the mute button on the TV remote - although this will silence the TV speakers, you wouldn't normally expect it to affect the RCA output (failing that, just turn the TV volume control right down).
