House Speakers/ Laptop speakers

Just got a Dell Inspiron 15 laptop and use an audio cable to connect to my stereo receiver and speakers. The speakers are working, but so is the laptop speakers. Any idea how I shut them off so the sound doesn't compete with my house speakers.

Hello. To correct for a possible configuration issue, re-install the audio driver.

  1. Open the Device Manager (find it in the Control Panel, or type devmgmt.msc into the search box).
  2. Expand the "Sound, video & game controllers" category.
  3. Right click on "Realtek High Definition Audio".
  4. Click "uninstall".
  5. Do not check the box to “delete the driver software for this device”.
  6. Restart the computer. Windows will detect your device and re-install the driver, using the files that you did not remove in step 5. The reason this process fixes some audio issues is that it resets the driver settings to their default configuration.

After that, if it still happens then it is either a buggy audio driver or a defective headphone jack. To test the driver, switch between the Realtek audio driver and the Windows native audio driver.

  1. Open the Device Manager (find it in the Control Panel, or type devmgmt.msc into the search box).
  2. Expand the "Sound, video & game controllers" and right click on "Realtek High Definition Audio".
  3. Select to "Update Driver Software".
  4. Click on "Browse my computer for driver software".
  5. Click "Let me pick from a list of drivers on my computer".
  6. Put a check in the box "Show compatible hardware" if not already checked.
  7. In the list of devices, click "High Definition Audio" (the native driver).
  8. Click "Next".
  9. On the Update Driver Warning box, click "Yes" (install the driver).
  10. Restart the laptop if prompted. If not prompted, sometimes you have to restart, sometimes not.

[To get back to the Realtek driver, do it again but reverse the names in steps 2 and 7.]

If you only have the symptoms with one of the drivers, then the other is at fault. If you have the same symptoms with both audio drivers, then it could well be a hardware defect.
