No sound at all. FAO is off Speaker says on. Set on stereo. Will an outside speaker work? Where to find speaker? Must use stereo?

I would check two things... First make sure your wires are not connected in reverse order from the speaker to the cassette deck. Second I would check for a short in the wire between the speaker and the cassette deck. You can do this relatively easy with a fluke meter. That's all I can think of hope it might help

Check the reciever and verify if you have a selector swicth pressed for A speakers and B speakers and see if this helps...

Some recievers will only power A or B, not both at the same time.

Lets not assume your outdoor speakers work. Would be helpful to know if you have tried to disconnect the inside set and plugged the outside speakers in those stereo jacks. If no sound, your speakers may have loose wires on the inside of the box/cabinet/case or they could be no good period.

If they do work, and the system does not provide all four jacks to be powered at the same time. You may consider buying a pair of piggy back rca jacks. Plug in the indoor and outdoor speakers into the same connectors the indoor ones are on now.

That way at least you can run them all at the same time from the speaker connector where you have the indoor speakers hooked up..

Hopefully you'll find something useful in this

Good Luck

check your speaker wiring, make sure both terminals are connected properly. or could just be left speaker is disconnected. and is set in stereo mode which will only play left and right front and Sub, if you have one. try chaning the surround mode to play in multi channel speaker which will send sound to all speakers. i trust your using a Digital audio cable from your source ( cable box, DVD player) if your using analog audio cable you will only get stereo sound, and nothing will ever come out of the rear speaker unless you change the surround mode to multi- channel speaker. also in the setup menu you should be able to perform a speaker setup, make sure all your speakers are able to produce sound. follow speaker setup mode in menu, make sure you have checked the boxes or Yes to speaker you have in your system. then perform calibration and a test tone will come out of each speaker as you select them.

This might be helpful. Most stereo receivers have 2 sets of speaker outputs, A and B. Each have outputs for left and right speakers. On the front panel of the receiver, there should be a switch to turn on/off speaker A/B. When using both A and B, (a set of speakers on each A and B) you will lose a bit of volume.

Another possibility is, if the speaker cable length to your covered porch is a long distance from the receiver, you will lose some power from the receiver. Try using a thicker gauge speaker cable for longer cable runs. Try 14 gauge or 16 gauge.

There are a couple of ways to go about this. The first would be to locate a similar computer speaker system set up outside - provide power and extend the cable to them - if not too far. When you want to listen to the outside speakers, plug the cable into the headphone jack of the computer. Adjust volume and enjoy.

Another way, would be to buy (or build from kit form) a low power FM transmitter. These devices are available in mono & stereo types and will play over all FM radios and stereos in a 50 to 300+ foot radius (depending on antenna, wall construction, transmitter power, etc.) when they are tuned to the transmitter frequency. These can be found for under $100 or built for as little as $30 or so. The upside to this method is that the music is available over ALL radios nearby.

Still another way is a wireless speaker system. This works like the FM transmitter, but will only work on these particular speakers. These will require power only - but some will work from internal batteries as well as AC power. The system includes a small transmitter, power cord & cable to plug into a headphone jack - all for use at the computer, and two speakers - each with a power cord as well and possibly a remote control.

Use of a spare pair of old stereo speakers will probably not work as the computer's sound card rarely develops more than a watt or two - and most home speakers require 10 or more watts to be driven properly.

Sounds interesting.
It may sound silly, but can you check all your speaker cables again and confirm whether they are connected to the right connections. please check all cables as also the severed one and please repair it also.

Now please go to the system-set-up and do an auto setup and set up your speakers. Listen to the test tones and confirm that they are coming out of the correct speaker.

Once these are set, then if still there is mismatch of sounds, then we could further trouble shoot.

You won`t get surround sound mix with 2 speakers, you can have a 2nd zone but this will only play a "Stereo Sound" if you have that playback option with the SC-RT50, what you will need is a speaker selector switch or better known as an A & B switch, this will ideally run from the front left and right speaker output of the receiver into the A & B switch then run into each pair of speakers inside or outside, what is common nowdays are receiver that are known as 2nd zone connections where you can have 2 sets of speaker in different rooms, unfortunatly the SC-PT50 does not have this option.

The FAO that is showing up when you try to adjust the volume because the volume has been turned off to make the TV work with an audio receiver.  The sound was set up on the television to be off so that the sound came out of the audio receiver only.  I don't know your exact model's instructions, but I know on my Sharp instruction if you go to the Menu and then go to Audio Select and make sure FAO is off and Speaker is on.  This should allow you to adjust your televisions volume level.  

Make sure your amp is set to a channel which plays on all speakers (5.1).
If you have the amp set to "Stereo", it is only the frontspeakers and subwoofer which play sound.
