My PC is an HP Pavilion T3777 running Windows Vista SP1. For over a year the sound system has worked perfectly but last week it ceased to do so and no sound is heard when I try to play a CD, watch a video clip or listen to a track from iTunes. Can anyone suggest what may have happened or suggest diagnostic tests?

First, make sure all the connections are connected properly (I guess that's obvious, but it doesn't hurt to check :thumbsup: ).

Next, does your computer detect the speakers? If you go into control panel, and click sound, it should say speakers. It also let's you test them, try testing them, and see if they are configured properly.

I would also recommend trying the speakers with a different computer, and/or trying another set of speakers with your computer.

Thanks to the three who responded to my problem.

Garmanma suggested a driver update. I implemented this but to no effect.

Starcraftmaster suggested looking in Device Manager. DM thinks everything is working properly.

Following Sterling14's suggestions I checked the connections -- they were all in order. The computer did detect the speakers, said they were working and, indeed, showed their volume variation as I played a CD. I went to the Control Panel and tried testing the speakers -- the graphics showed waves emanating from the speaker icons but not a sound emerged from the speakers themselves. Finally I exchanged the speakers with another pair that were connected to my second computer and were fully functional. They no longer functioned but the original ones now did.

So I remain totally confused and without sound.
