Sound problems I moved my computer recently and when I plugged it all back in the sound wont work. I've gone to device manager and its says everything is ok. I can hear sound if I put headphones in so I dont think it is the speakers. Dont know what else to do

This is a windows problem. The speakers are connected to a sound card which is the device that would show. You need to reinstall the drivers for your sound card.

if your computer came with a motherboard disc the sound drivers could be on it
click start control panel administrive tools computer management device manager scroll to sound,video and game controllers you might see a yellow question exclamation mark? ! or a red X Right click to reinstall drivers
click start control panel sounds and audio,volume,advanced,speakers make sure you have selected the
(((appropriate speakers))) also audio you will find 3 drop down lists make sure you have the correct settings there
also
click start control panel sounds and audio devices select advanced there might be a tick in the mute box untick it
if his does not fix the problem
click start control panel sounds and audio devices you can adjust the volume there also select speaker volume you can change your settings there you can also tick in the box place icon in taskbar for any further volume control settings you will need to right click on the volume icon system select adjust volume

click start control panel sounds and audio,volume,advanced,speakers select the appropriate speakers from the drop down list or navigate to the device manager scroll to system devices + to expand,system speaker right click properties then select use this device (enable) also you might check
the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good
try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the sound card and the CPU central processing unit dust causes static to build up in a computer hope this helps

Hello patrick886,
If your volume mixer is still showing the noise bars moving, that's great. It means the computer knows sound is coming from somewhere, the fact that you can't hear it, indicates there's a problem with where to send that sound (aka your speakers). Now with the no sound coming out, I'm guessing you are talking about the internal speakers and not external ones.
Have you recently installed any kind of music editing software? Mp3 player such as Winamp, iTunes or other music related programs? I'd start by checking the device manager to see if the speakers are at least being detected.
I've put together a nice little picture for you. Hope it helps!!

There are a few simple things to check first:

• Make sure your computer has a sound card.
  

  You must be logged on as an administrator to perform these steps.
  

  1. Open Device Manager by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking Device Manager.‌ If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
     

  2. Expand the Sound, video and game controllers category. If a sound card is listed, you have one installed. If no sound card is listed, You will need to install one. See Install or remove a sound card.
     Note

     If you think you have a sound card installed but you don't see it under the Sound, video and game controllers category, expand the Other devices category and check any devices listed there.
     

  3. If there is a yellow question mark next to the name of the sound card, there might be a problem. Right-click the name of the sound card, and then click Properties.
     

  4. Click the General tab, and then look in the Device status box to identify problems with the sound card.
     

• Make sure your speakers are plugged into a working power source and turned on.
  

• Make sure your speakers are correctly connected to the computer.
  

  On your speakers, find the cable that plugs into your computer. Make sure that the speaker cable is plugged into the speakers and the correct jack on the computer. For example, if the cable is a 1/8 inch cable, there should be a round jack for it on the back of the computer. If it is a universal serial bus (USB) cable, it will plug into any USB port on your computer.
  

• Make sure that the speaker volume is not muted or turned down too low.
  

  1. Open Volume Control by clicking the Start button , clicking Control Panel, clicking Hardware and Sound, and then, under Audio Devices and Sound, clicking Adjust system volume.
     

  2. Under Main Volume, move the slider up or down to raise or lower the volume.
     

  Note

  Some mobile PCs have an external volume control on the outside of the case. If you're using a mobile PC, check the external volume control.
  

• Make sure your headphones are not plugged into the line out (headphone) jack of your sound card or computer (unless you want to be listening with headphones rather than speakers). When you plug in headphones, most computers automatically cut the sound to the speakers.
  

• If you need more help post back!
  Thumbs and testimonial are welcome!

I know this was old query, but i recently had a problem with sound cutting out. Discovered if I jammed a spoon between the two cables input to the sub box, I could get sound back. Today finally got around to opening it up and discovered the soldering on both sides of the 8 pin anchor leads were broken. The pressure of the spoon jam allowed the connection to "seat" temporarily. Fixed with 25w iron and 60/40rosin core 0.032" solder. Wicked the old broken mess off and applied dab of new shiny complete solder. Good Luck all.

Hi try looking over it again with the help of this https://www.download.p4c.philips.com/files/s/spa7300_79/spa7300_79_dfu_eng.pdf just make sure all connections are pushed in properly as those plugs have a tendency to not plug in all the way

go on the net and download the drivers for that make of sound card

Please try to check the sound device status if its working properly thru right click My Computer icon > Properties > Hardware tab > Device Manager > (double click) Sound, Video & Game Controller OR System Device > System Speaker. also, take note of the Troubleshoot tab. If still it doesn't work, I think you have to reinstall the sound driver (from its motherboard software CD if it's built-in type). best regards

go to device manager locate the speakers, right click and update drivers, if that fails search google for that sound card driver.
