No sound output from rear speaker jack

After getting an FM transmitter to work through the front headpone jack, I can no longer get the rear output to work with the speakers. The speakers will work on the headphone jack but not on the rear jack. The green light for the headphone jack in Realtek HD Audio Manager stays lit whether anything is plugged in or not. The rear jack indicater light lights up only when something is plugged in. How can I get the headphone jack to go off when nothing is plugged in?

    Thanks for your response. I didn't explain clearly. With nothing plugged into the headphone jack there is no output from the rear speaker jack.

    Windows Vista. I think I am getting this figured out. The Realtek Audio Manager has a window that pops up when something is unplugged or plugged in which then asks if it was front or rear speakers or headphone. I must have identified something incorrectly. I am getting sound through bith jacks at the same time just now. I obviously need to find the Audio Manager help file.

    I think I am OK now. Thanks again for your response.

Plugging headphones into the computer will disable sound output from the sound card by design.

    When you look at your Sound Mixer, do you see Rear as one of your controls and is it turned up? Windows XP or Vista?

To add to my request a manual for AWA 17cm DVD/CD/AM-FM Television Micro System

An FM transmitter is a portable device, which converts a specific audio output into an FM radio signal. It can be plugged into a CD player, satellite radio system, headphone jack, or a portable media player. One common use of an FM transmitter is to play music from an Mp3 player through the speakers of a car.

How do I conect external radio/speakers to my lg 42lh40-ua

There are many options here. Most HDTVs today have analog audio and digital audio output jacks. You can use RCA audio cables or a 3.5mm connector, whichever your HDTV has to connect the analog stereo output of the TV to any number of devices such as a stereo/amp which has speakers attached. You could also connect an FM transmitter to the TV and send the audio wirelessly to a nearby FM radio, boombox, portable etc. Most HDTVs today have a digital audio output, typically optical, which uses a digital audio cable ($15) to connect to a surround sound receiver. You can also connect the stereo analog output jack on the TV to a 2.4GHz transmitter and receiver speaker combo to get wireless audio outside, in a swimming pool and so forth, all around the house using wireless speakers. These setups usually cost around $150 or so. Look for the jack on the TV labeled AUDIO OUT and see if it is the white and red 2 jack ports or the smaller 3.5mm single jack port. Adapter cables are available at Radio Shack for around $10 should you need them. So you see the options are almost endless.

I am having the same problem with a twist, sound works from the fm and headphone but only from the right side no left audio. I have the 760 and it only has one speaker and my guess it that it gets its feed...

If you use the headphone jack a lot and your missing the audio from the speaker and one channel from the headphone jack, then it's possible that some of the headphone jack connections have broken off of the PC board. The audio goes to the speaker through the headphone jack.

Please see this link for more info and read the section about the headphone jack.

No sound when put on 88.3 fm

I didn't think this unit had an included FM transmitter - so I looked around for more info, and everything I've found indicates it does not.

It will however play audio via the built-in speaker or headphone jack. Use of a third party FM transmitter will allow playing audio (navigation, alerts, MP3 or audio books) when connected to the headphone jack and with both the FM transmitter and FM radio set to the same frequency.

The FM transmitter will work best when set to a frequency that is unused and has the least amount of interference from adjacent stations. Check by tuning the car radio across the FM band and note frequencies that have those qualities. Leave the radio on one of the clear frequencies and set the FM transmitter to the same displayed on the radio. You should try several to find the one that works best. Also, be aware that as you travel, you may enter an area where that frequency (or one close by) is in use by a broadcaster. This will require repeating the process as needed to reduce interference.

Is it possible to connect my PC to my outdoor speakers? I want to play music outside using my PC. Is there a special connector that I need?

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.

Connection compatibility

Connect the supplied short RCA "Y" adapter cable to the mini jack of the transmitter base unit. Connect the "Y" adapter plugs to the TAPE 2 "REC" L and R jacks. These jacks will supply "line out" levels of any source selected at the Kenwood to the EWOS1 internal amplifier. The line out levels are "fixed" so changing the volume levels of the Kenwood will NOT change the volume out of the EWOS1 speakers. The EWOS1 volume will be controlled by the volume up / down buttons on the front of each speaker, or by the incuded remote when directed at the speaker(s).

The signals from the TAPE 2 jacks are ALWAYS on regardless of the source selected, so the Kenwood volume can be turned to minium and still provide an unchanged sound level from the EWOS1 speakers. Likewise, if listening to FM, Phono, CD, etc. in the room that the Kenwood's speakers are located, the OWS1 speakers will by playing the same FM, Phono, CD, etc program - unless they have been powered off. The point is, that unlike having to choose FM, CD, etc to listen to those soreces, you should never select TAPE 2 as a source. If TAPE 2 is selected, the KENWOOD would attempt to amplify TAPE 2's "PLAY" jacks, which I assume are not being used.

No sound from Garmin nuvi 760 by any method

Sounds like your speaker went south. Since your fm transmitter is working I'll be your earphone jack is too. So you could always use an earphone. Only other option is a speaker replacement.

HI Heather,

Make sure you don't have the sound muted. Have you tried plugging in a set of headphones into the headphone jack? If you can hear sound with the headphones, most likely, the internal speakers have failed. If you still can't hear any sound, the audio output stage on the motherboard has failed. In either case, you will need to send the unit back for repair. Be sure to have your serial number handy. Register it online
if you haven't already done so.

More Info: If you can hear sound through the speakers and don't want to send the unit back for repair, you can buy a FM transmitter at Best Buy - the kind that will allow you to play a portable CD player through your car stereo. Just plug the transmitter's audio input cable into your GPS headphone jack, power the transmitter with your car lighter jack, set the transmitter frequency to a unsued FM channel and tune your car stereo to tha same channel. You should hear your GPS through your FM stereo.

Good Luck,
- Jim
