Headphone jack does not work, audio still plays from speakers

These are analog speakers and do not need a driver. First, make sure they're plugged into the speaker/headphone jack and not the microphone jack. Second, make sure the computer's sound output is enabled and set the headphone/speaker jack. Third, verify that the sound output is working by plugging in a headphone set or a different pair of speakers. If the computer sound checks out, the speaker cable is bad or the power supply is not working.

Normally , you would expect the TV sound to stop when headphones are plugged in. Obviously not in this case. If you have a set of headphones, try them and see if the TV still has speakers on. If it does, then there may be a setting on the setup of the TV to get headphones to work. If the TV speakers stop, then I would think that the Logitech are not compatible with the TV. The only other thing would be is to get into the TV and disconnect the TV,s own speakers. If the wires are soldered on and not terminal connected, carefully cut 1 of the wires off near the speaker. If 1 wire is cut, the speaker wont work. Make sure both the TV and the additional speakers (If they have their own power supply) you are using are unplugged from the power before you go doing this...!

The headphone jack has a switch in it to disable the speakers when the headphones are plugged in. This switch has stopped functionong. Look in the jack eith a magnafying glass to see if there may be lint or some other object holding the switch open when the headphones are not plugged in. Otherwise it's time to replace the jack.

No the headphone jack doesn't disable the speakers. There are two switches in the lower middle of the receiver that are labeled speaker A and B. Pushing one of these should disconnect the speakers from the receiver.

If you don't plan on using the headphones - take the cover off and there may be a cable to the headphone jack board that can be unplugged. This will disable the headphone jack from sending a bad signal to the micro. If you want to be able to use the headphone, then the jack is going to have to be replaced.

Hi,

I find that there is a problem with your headphone speaker.
Try with some other headphone, even if it is not working, then you need to take it to the service center.

go to the control pannel, then go to sounds and audio devices, then click the audio tab across the top. under sound playback, choose your speakers as the default device. solution only works like this for windows xp. good luck

Try changing the Windows Default Audio devices

1. Go to control Panel
2. Sounds and audio devices
3. The Audio tab
4. Then change the Sound Recording Device to Logitech Headphone INPUT
   

Hopefully this will work

I had the same problem... but I knew that my 2 yr old had been playing with the headphone jack on the BC-150. Evidently, the system thought that headphones were still plugged in to the port on the front right of the unit, even though none were present. The solution that worked for me was to take some headphones, plug them COMPLETELY into the system (another set of headphones would not insert all the way, so I found a new set and used those to completely insert into the headphone port) while playing a CD and listen for a few seconds and then simply unplug them. Viola! Sound came back. Hope this helps.
