Question about HP (400745-001) Sound Card

1 Answer

Speakers don't work!

After I switched out my old computer monitor with a Dell monitor to match the tower, my speakers stopped working. I checked the Control Panel over ten times and it looks like my volume is all the way up and they should be working. The speakers are plugged into the right slot, and they are on. Please help? :/

Sometimes, the colors on the jacks should be reversed. Try doing that - reverse which colors the jacks go into on the back of the PC and see if you get sound that way. Turn the volume down, just in case,

Where is the speaker bar plug on a dell monitor


This plugs into the tower unit sound output. It is on the back of the tower and will have a speaker icon. There is no sound out on a common dell monitor.

Old Altec Lansing (no model number on them but they're at least 10 years old) speakers won't work on new Dell Optiplex desktop. They still work on the old Dell Dimension they were on and work on a Del


I have a similar set of Boston Acoustics speakers, which work fine for my tower.
I find it hard to believe that they would just fail outright, and also that (unless you bought an upgraded sound system) you would have digital-only for your audio.
I would recommend to check the basics first.
  1. Check the speakers on another device. Mp3 player will work fine.
  2. check the sound card on your computer (use a set of headphones or another speaker set).
  3. If you find they weren't plugged in, powered on, etc. resolve that. Usually the power plugs are black, and only fit in one spot. The audio cable to plug into the computer is similar to a headphones jack (3.5mm). On most computers the audio output (speakers) port is colored green.
  4. If none of these get you fixed, go into the control panel and click the sounds icon. From there you can view your volume levels (is the sound muted?), view your playback device (it might have a hardware problem, or be disabled), and test the settings.
  5. If you are still stuck after this please also post your version of windows, and the make/model of your computer. If you know it, the type of audio device you are using would also be helpful. (if it's a Dell standard device or perhaps an upgraded Creative or other brand device + model #)
Thanks for asking, and Good Luck!

I need to connect my old speakers to my new Samsung monitor. No instructions in manual. thanks, barb


You don't connect speakers to the monitor, you connect it to the tower of the computer. If I'm not understanding your question right then please be more specific. If your monitor has speakers, you connect the audio cord to the tower then to the monitor or vise versa.

Speakers killed my moniter


Well as you have already tried disconnecting the peripherals from your computer, and tried restarting the computer too which did not help you, it sounds to be an hardware issue with the monitor. However if incase you have not tried this, you can disconnect the monitor completely from the tower, power on the monitor, if it powers on and you get a message as no signal, your monitor is working good. If not replace the monitor. If the message appears on the monitor screen, disconnect everything from the tower, push and hold the power button on the tower for a minute. Connect just the monitor and check for any display. If you do get display, thats good, connect one device at a time and check to see if the display appears.

If theres no display with just the monitor connected, the issue would be with the graphics card. You may need to replace it or get the system repaired.
