Lose of external speakers volume and balance controls

Take a balanced mic lead from the Monitor out socket on the SA220 and that will feed your powered speaker.
Use the monitorout control to adjust the signal level to the powered speaker and the powered speakers volume control for a balance.

If it's plugged into a external speaker system, doesn't the external speaker system have volume control? In the Tray Notification Area, right click or click on the Sound Icon, adjust volume OR open the Control Panel and select Sounds Icon. Laptop aren't known for great sound, I use this: http://www.bose.com/controller?url=/shop_online/digital_music_systems/sounddock_systems/sounddock_portable/index.jsp

TRY CONNECT THAT SPEAKER TO OTHER COMPUTER FIRST. THEN ALSO CHECK-UP POWER ON LED , VOLUME CONTROL AND AC PLUG.

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.
   

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.
  

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!

Probably.
Do they connect to the computer via USB or mini plug?
If mini plug, make sure you have the right jack on the back of the computer (there's two)
Then go into System Preferences ... select "Sound" and see if you can select something other than "Internal Speakers" - the computer may just not be aware that you want to use the external speakers ...
Are the speakers powered? Is there a volume control on the subwoofer, or an external fob with a volume control on it? You probably know this if you used them previously with your Compaq computer ...

Good luck!

Make sure the balance control in your VOLUME CONTROL icon in windows tray (by the clock) is centered....
There are sliders for each output/input and a balance control for each of these. uncentred they can switch off one channel.

I'm sure you went to Control Panel, opened device manager, and and checkeck for any yellow checks for your
sound, video and game controllers. If there are none, your system is go. Then go to your audio manager on control panel, and set it up for whatever speaker configuration you have. I have realtec audio manager. This step is a must for configuring—you choose whether your laptop will use its own speaks or use your external speakers—you have to turn off the internal speakers and turn on the external. Did you forget?
