No sound coming out of head phones

ibm sound card is not faulty, because you are getting sound with your head phone. The head phone jack have two functions 1. to give output to head phone 2. to disconnect internal speakers when you plug in head phone.
The jack for headphone in normal position not give connectivity to internal speakers.
SOLUTION : REPLACE THE HEADPHONE JACK.
I think it will help you.

Hello,

Hello,

It is because that your internal speaker is the default play back device other than your head phone or external speaker.

Need to go to your sound setting.

Depend on your operating system, click Start, then click Control panel, then click Hardware and Sound, click Sound.

Under Playback tab, select your external speaker or head phones as default device.

Well we have eliminated the laptop as a problem,.. that is very good. As far as what the problem with your BA unit is,.. we only know that it does not function with an external device (laptop and mp3 player). you already mentioned that a sound test from the unit plays through all the speakers,. right? With that lets start with the most basic item that will cause this problem,.. the cable that comes from the BA unit and plugs into the laptop or mp3 player. Is the cable plugged into the right place on the BA unit? Does the cable disconnect from the the BA unit? if so, do both ends of the cable look the same or is there 2 ends (maybe red and white) that plug into the BA unit? Please let me know when you can and we can continue troubleshooting this.

Plug some speakers in to the headphone socket instead? Please use speakers that you know work (test them eith your ipod or another device)

When it was knocked over it may have cracked the main circuit board, but does the pilot light come on at all? If the pilot light comes on but no sound is output from the speaker try plugging some headphones into the head phone jack and then turn it on and see if you can hear sound in the headphones. I have had a similar problem before and the main speaker had gone bad but it would still play thru the head phone jack.

You can get this speaker through whistler ,, i have this same unit and its 10 dollars shipped.. here is the phone number you will need. 800-531-0004

A quick way to check your speakers is to put the contacts from a 9 volt battery to the positive and negative speaker wires (briefly). You should hear a crackle of some sort if the speakers are functioning. If there is no crackle, speakers are bad / if there is a crackle, your head unit must have a problem.

I just fixed mine. Plug in your head phone. wait couple of seconds. you will hear clicking noise which seems to reset the receiver. 10seconds later, sounds should come on and if not unplug the head phone and you should hear it then.

sounds like headphone plug in is bad sorry no way to fix this unless you reinstall new head phone plug in .. lala linda

yes thats the fact when you plug a headphone into any speakers the head phone will be the only one to function the speaker stops thta the circuit technically which will break the connection of power to speaker if you plug head phone
