Motherboard sound and old speakers

External speakers usually require a power source. This may be provided by USB, power adapter or sometimes batteries.

They need to be plugged in AND switched on. And the audio plug needs to be in the audio socket - easily confused with a microphone socket

If you have checked that and they still do not work, you may have damaged wiring.

One last thing. Some digital speakers require a special digital socket - although the plug is the same. Check that your speakers are analog for use with a standard audio output!

You don't mention the sound card(s) in the PC nor the method of connecting to the monitor. Some video cards have HDMI connections for audio and video out to a monitor and will not allow any other audio outputs to work. Regardless of sound source interface, check to be sure that the audio source is the one that is NOT part of your video card and is NOT set to output DIGITAL audio signals.
Once this is done, select the the "add-on" or "expansion slot" sound card (if it is the type that plus into a slot on your motherboard) or the "built-in to the motherboard" type (if the jacks are soldered directly to the motherboard) as the DEFAULT or ENABLED. Set to ANALOG output - NOT digital if a choice is offered. Connect the speakers. This should be via cable terminated with a stereo mini jack - NOT a special digital optical or coaxial cable / connector. Most modern PCs will have several mini-stereo jacks from which to choose - nearly all use the GREEN ringed jack for the FRONT (or main) left & right stereo speakers. Regardless, if yours has GREEN jack, you should use it - if none have a color code, look for markings that indicate either "speakers" ,"output", "front" or "L & R". If there are no indications, check your manual. Set your volume level on the lower side, play an audio source and adjust speaker volume and / or audio mixer settings in the system tray as needed.
Only one sound card will work in a PC. Make sure that all connections are made to the ENABLED card, otherwise no sounds will be heard. Digital output is primarily targeted to facilitate connections to external amplifier and speaker system - most often like those found in a Home Theater PC setting - or a monitor / TV connected by an HDMI cable.
I hope this helps & good luck!

hi
maybe you have loss in jack connection otherwise check sound setting in volume bar right corner of desktop

Two audio input cables are supplied with the speakers. If your computer has a stereo mini jack, use the cable with a stereo mini plug. Otherwise, use the cable with RCA plugs on both ends. Match the colors on the connectors to the colors on the jacks, red to red and white to white.
The speaker cable is already attached at one end to the accessory speaker. Plug the other end into the TO ACCESSORY SPEAKER jack on the powered speaker.
1. Connect one end of the audio input cable to AUDIO INPUTS A. 2. Connect the other end to your computer's AUDIO OUTPUT jack. We recommend using LINE OUT if your computer sound card offers more than one option. 3. To connect a separate CD-ROM, or another source, repeat steps 1 and 2 using AUDIO INPUTS B.
You must connect the AC power pack to operate the speakers. 1. Plug its cable end into the power jack on the powered speaker. 2. Plug the power pack blades into the wall outlet. 3. Turn on your computer sound source or external sound source.

Please check the below mentioned things :
Verify the AC power cord is plugged into the wall outlet. Turn the VOLUME knob on the right speaker until you hear a click sound. An LED will light next to the knob when the power is ON. Turn the VOLUME knob clockwise to raise the volume. Check volume level on the computer sound card or alternate audio source device, and set at mid-level. Check plug connections on the audio source. Make sure the signal cables are inserted firmly into the correct jacks. Make sure the 3.5mm stereo cable is connected and fully inserted into the "line-out," "audio-out," or the headphone jack of the audio source. Test the speakers on another audio device. Remove the 3.5mm stereo cable from the audio source device and connect it to "line-out," "audio-out," or the headphone jack of another audio source.
And if in in case u r unable to get it working ..
Replace the speakers ..

Hi friend,

Fristly you check sound drivers are available on your system or not,go to the control pannel and open the sound option,if it is disable thats means sound drivers are not available on your system,in that condition you need to install sound drivers accourding to your system motherboard,if it is showing enable in that condition you plaug the speaker jack propely as per colour codding in back side of CPU.
When you plug the jack properly one sound pop ups are coming o=in your screen plaese press ok and ok,
If you are using 5.1 or 4.1 speaker please check proper supply to speaker adapter.

Thanks

If there is not a separate jack for speakers and headset, then you will have to unplug the speakers and then plug the headset into that jack. Some motherboards only have one audio output.

I'm assuming you have the little jacks for the speakers to plug into.... As crazy as this sounds, make sure you have the speakers plugged into the right jack. The icons by the jacks are not all that clear. You might have the speakers plugged into the "Line In" jack? I've done it myself and I'm a Computer Engineer!

Hi,
Usually the power on button only has two wires. Then you have HDD led leads, reset leads, power led leads etc. These are all separate wires that fit onto separate pins in the Jpanel1 (front panel header).

Could be that the really old emachines grouped all these wires and made them into a plug to fit their own style motherboards.

If this is the case then that connector would not be on your newer motherboard, and it would have that Jpanel1 instead.

Hope this helps as I'm not very familiar with the old emachines.

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.

3. 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.
• 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.
NoteSome 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.

thank you
