Problem with sound on PC

Annie1960

I know I am doing something silly, but I can't work out what.

I have an HP tower computer with monitor. It was all working perfectly until I moved house recently.

I have set the machine up in my new place, and it works OK except for the sound.

I have a subwoofer with 2 small Dell speakers that I had from my last computer.

Yesterday, I unpacked the speakers and subwoofer. The speakers have 3 cables. Two connect via an orange-colooured connecter that screws in to the back of the subwoofer. The other cable has a green jack plug on the end, and I plugged this into the green socket on the back of the HP tower.

Finally, I plugged in the subwoofer to the electric socket.

The light has come on the speaker, so I know it has power. However, I can't get any sound. I have tried turning the volume up on both the subwoofer and the speakers.

What am I forgetting to do to get the sound to work?

Very confused!


EDIT: I'm running Windows 7 if that makes any difference.

Try the black socket on the tower, green is usually for line out.

Thanks for the suggestion.

I have looked on the tower, and there are three sockets.

blue - in
green - out
pink - mic

There is no black socket.

you need to reset the default sound device...with the speakers plugged in to the green jack socket...

Check sound isn't muted, by default Win7 mutes the sound outputs if it is started without any speakers connected, it stays this way until you unmute.

Speakers are plugged in to green jack socket.

Still no sound, however.

Checked. Sound is half way between muted and very loud.
Still no sound!

Do speakers have power? Where's the light? Do the small speakers get power from subwoofer? Best to check speakers out with a different sound source.

All is well now. I fiddled around in here, and found a button called 'test'. I clicked it, and heard a very, very faint sound. Turned up the volume wheel on the speaker, and it works.


Thanks everyone for the suggestions.


I did say in my OP that it would turn out to be something very silly I was doing wrong. The volume wheel must have somehow got turned down during the move.
