My hp pavilion doesn't have a sound. The drivers

try installing proper drivers for the AUDIO CARD! the orange led only indicates the HTK HOTKEYdrivers are working properly, it does NOT says a thing about audio card drivers! so i suggest you to install proper drivers for audio playback!

Make sure the volume is turned up and not muted. Check the device manager to see if the sound/audio devices have any conflicts or is not working properly. If you have a megaphone at the bottom right near the time, right click on it and select properties to check it out. You might also click Start/Control Panel and look for Sound/Audio in there to check out.

You can always download your Audio Driver and reinstall it.

Get onlineand got to www.google.com In the google search box type: "AcerSupport" (without the quotes). Look for downloads and drivers. Enter your model number and operating system when requested. Download andinstall the drivers.

a 10 year old PC,
that means you lost your HP drivers for sound
or is a hardware problem. dead internal speakers.
so, you posted not telling what OS you have, making
the OS to hardware driver match impossible.
so today I teach how to fish.
go to hp, tell Hp what OS you have get the sound drivers.

check whether the drivers are installed properly and try by re installing the driver after removing the existing sound rivers
This can be done by using the device manager
In the device manager you can find whether driver is installed if it is installed and not working means right click it and give uninstall ,automatically it will search for drivers and ask the required driver or it install if backup is present already

Sir, i have HP Pavilion dv 1000 (XP operating system). Recently, i upgrade it by Window 7 but Now audio driver is not working properly now. pl suggest to solve it.----- pratik

go to device manager remove the drivers then reboot your system then install the drivers, then check,

Try:
1. Check if the sound is on mute.
2. Click on Start and select Run. Now type devmgmt.msc and press enter. Check if the sound driver is not installed or has been disabled.
3. Check the speakers. Use external headphones, if the headphones are working properly, means the speakers of Laptop are damaged.

try downloading and installing the latest audio driver from the HP website. choose your operating system and the website directs you to the drivers. sometimes windows updates install the wrong drivers ans causes the hardware to malfunction properly, so try uninstalling these updates using system restore point, if this doesn't work do the first step.

Try to plug in remote speakers or ear phone to make sure the speakers have not quit on you.

I was having a similar issue. My volume button worked fine muting and unmuting the volume, the light just stayed red either way.

I went into Device Manager, then expanded the Sound, Video and Game Controller options, I rolled back the driver and it was an instant fix for me :)
