No sound I lost the sound on my laptop.  I don't see where anything is on mute.  The sound was working.  I tried to connect some external speakers and now the sound is gone.  Any suggestions

Not uncommon with HP laptops. Usual faults are network cards that suddenly die, graphics chips that unsolder themselves and (less common) the sound chip blowing.

I'm assuming you already checked if the sound has not been muted first?
You have up to date sound drivers

Test by connecting external speakers, if they work (and you have the sound unmuted), it is the internal speakers in the laptop that are at fault and will need investigation. If the externals do not work, then the sound chip is blown.

Apart from replacing the motherboard, you have the option of getting an external USB soundcard and running that to speakers. A bit clumsy, but you will get much better sound quality

Hi,

Welcome to FixYa!

What do you mean it stopped working? No sound at all?

Please try the following:

1. Please make sure the sound is not set to mute. Try to adjust the sound volume.

2. Reinstall the audio driver. You can do this using the drivers disc that came with the computer or you can download the audio driver from the computer manufacturer's website: http://support.lenovo.com.

3. Try to connect an external speakers or headset. If you can hear sound on an external speakers or headset then the internal speakers of your laptop is already defective.

Hope that helps. Thank you for using FixYa!

FIRST OF ALL CHECK THE SOUND SYMBOL OPTION ON THE SYSTEM TRAY IF IT IS IN MUTE AND ALSO RIGHT CLICK ON THE SOUND SYMBOL TO GO TO THE MIXER TO CHECK IF ANY MUTE OPTION IS CHECKED IF EVERY THING IS OK,THEN THERE MIGHT BE A PROBLEM WITH THE SPEAKERS TO CHECK THAT INSERT A EARPHONE AND TRY TO PLAY A SONG AND SEE IF YOU CAN HEAR IT IF YES AND WITH THE EXTERNAL SPEAKERS WITHOUT THE EARPHONE IS NOT WORKING THEN THERE IS A PROBLEM WITH THE SPEAKERS.
MOST OF ALL THE SPEAKERS COULD BE IN MUTE.

• click on the volume icon on the right hand bottom corner of the screen and check if the mute is checked.
• right click on my computer>click on properties>click on hardware>click on device manager check the audio driver has been installed or not.
• try to download latest audio driver from the support site.
• connect external speaker and check if there is any sound,if you are getting sound you need to replace the internal speaker or need check the audio connection
• if you are not getting any sound on external speaker then computer has a faulty sound card
  

1. right click on the volume icon on the right hand bottom corner of the screen and checked if mute is checked.
2. go to device manager and check the audio ,if there is any exclamation mark,enable that.
3. uninstall the audio driver and restart the computer.
4. try to download the latest audio driver and restart the computer.
5. check the audio connection with the speaker.
6. connect any external audio speaker with your laptop.if it works then internal speaker need to replace
7. no sound with external speaker need to replace audio card
   

Generally when the head phone jack is inserted the speakers will get disconnected automatically.

If you are going to use external amplifier you can try the AV sockets. Opening the TV you may require the special screw drivers some times.

There are some possible reasons why the sound is not working. It could be the volume control is in "MUTE", or the right sound card is not selected in the volume properties, or the speaker is defective.

Here's what you need to do:

1. Try to connect an external 2-channeled PC speaker. The computer should recognize the speaker and the sound should be transferred to the PC speaker. If the sound works on the PC external speaker, then you know that the volume control is NOT in mute and the sound card is selected. It means also that the built-in speakers could be defective.

2. If the same problem occur after connecting an external PC speaker, check the volume control, and make sure that the "MUTE" box is not checked. Then adjust the master volume.

* If everything's properly configured, but there's still no sound, check the volume properties under the Control Panel. Be sure that the correct sound card driver is selected. If that did not help, try to re-install the sound card driver.

* And the last option, contact the manufacturer and have them fix it for you.

Thank you and good luck!

Have you "muted" the sound on your computer?

Have you "muted" any of the outputs (MIDI, speaker) on your computer?

Have you "muted" the sound on the TV's built-in speakers?

Have you "muted" the sound on any external speakers that are connected to your TV?
Does your TV have _more_ than one HDMI port? Have you tried them all?

Got a friend with a TV with a HDMI port?
If so, connect your laptop via THEIR HDMI-cable to their TV.
Also, connedct your laptop via YOUR HDMI-cable to their TV.

This could happen for several reasons. Of course, the first is that the speakers might have gone bad, but that is not usually the case.
The next reason would be if you have muted the speakers in the "sounds" option in the control panel. Check that. While there, be sure you have the volume up and not way down.

First check the controlpanel there is an option to take Sounds And Audio Devices Properties. then click on the AUDIO tab, check the Default Sound Playback Device.select the correct Audio divice.if the problem persist do the driver for sound ( multimeadia audio driver) from the acer driver cd.then try.
