Using this document to troubleshoot microphone issues
This document provides solutions to a variety of microphone/recording problems. This document is divided up into sections that deal with individual issues. Before performing any of the solutions in this document, test the equipment. After testing the equipment, select the document section that applies to the issue and follow the instructions.
Changes in software, settings, or drivers can cause a microphone to stop working. If the microphone recently stopped working, it may be necessary to use the Microsoft System Restore feature to correct the problem. For more information, refer to the HP Notebook PCs – Using the Microsoft System Restore Feature support document.

Test the equipment
To troubleshoot microphone recording problems, follow the steps below, depending on whether you are using an internal or an external microphone.

Test the internal microphone
The internal microphone is located near the top of the notebook LCD display or near the bottom of the LCD display near the hinge. Use the following best practices to capture sound more easily.
  • Adjust the notebook screen to place the microphone in the best direction for receiving sound.
  • Speak directly into the microphone. Avoid speaking away from the microphone.
  • When using the internal microphone, choose an environment without background noise.

Test the external microphone
Verify that the microphone port and the microphone are working properly.
  • Test the microphone on a known, working portable tape recorder, another computer, or a device that accepts the microphone connector.
  • If the microphone successfully records the voice, test the record function on the computer. If the microphone does not work properly on another computer or on a tape recorder, try using a different microphone.

Test the record function on the computer
Follow the steps below to verify that the recording program on the computer works properly.
  1. Click Start , All Programs , Accessories , and then Sound Recorder .
  2. Click Record and speak into the microphone. Save the file to an easily-accessible location, such as the desktop.
  3. To play back the recorded sound, open the file using Windows Media Player.
  4. If the recorded sound does not play back, continue to the next section of this document.

There is no sound or signal when recording
If, when recording with a microphone, no sound or signal is recorded, follow the steps below to resolve this issue.

Check the connections
Verify that the microphone (if external) is plugged into the correct jack in the front or side of the computer.
If the microphone is connected to the correct jack and there is still no sound, try unplugging the connector about 1mm so that the connector is sitting loosely in the jack. It is possible that the connector on the microphone does not match up correctly with the sound card jack. If this does not resolve the problem, push the connector firmly into the jack and go to the next step.

Check microphone settings
Follow the steps below to verify the microphone settings.
  1. Right-click the Sound icon in the system taskbar, beside the clock. Select Recording Devices from the drop-down menu.
  2. When the Sound window opens to the Recording tab, select Microphone . The Microphone entry should say that it is working, and there should be a meter beside the entry.
  3. Tap the plastic above the display gently. The meter should respond to the sound stimulus by rising and falling.
  4. If the microphone is not working, or if the meter is not present, or does not seem to respond to sound input, follow the steps below.
    • Click Properties . The Microphone Properties window opens.
    • Be sure that the device is enabled in the Device usage drop-down menu on the General tab.
    • Click the Levels tab. Set the microphone volume to 100.
    • Click the Advanced tab. Be sure that all of the checkboxes in this window have checks in them.
    • Click Apply , and then OK . Close the windows.
Try recording again to determine if the problem is resolved. If there is still no sound, continue to the next step.

Ensure the correct recording device is selected
To access the sound properties, follow the steps below.
  1. Click Start , Control Panel , Hardware and Sound , and then Sound . The Sound window opens.
  2. On the Playback tab, select the SPDIF Interface, or audio device.
  3. On the Recording tab, select the Audio device that is installed on the computer. It should be the same as the listing under Sound Playback.
  4. Click OK , and then close the Sound window.
Try recording again to determine if the problem is resolved. If there is still no sound, continue to the next step.

Remove duplicate soundcard entries from the Device Manager
If there are multiple soundcard entries in the Device Manager, they may conflict with one another. To determine if conflicts exist, and to remove duplicate entries, follow the steps below.
  1. Click Start , Control Panel , Hardware and Sound , and then Device Manager . If prompted, permit the action to continue.
  2. Click the plus (+) sign next to Sound, video and game controllers in the list and check for other soundcard entries that have the exact same name.
  3. If there are duplicate entries, select them one by one. Right-click each duplicate and select Remove until they are all removed.
  4. Click Scan for hardware changes in the Device Manager taskbar. Windows Vista scans the system hardware and supplies default drivers where necessary.
Try recording again to determine if the problem is resolved. If there is still no sound, continue to the next step.

Resolving microphone failure with internet software (chat rooms)
There are many reasons why voice may not work over the internet. These reasons vary, depending on the voice carrying software that you are trying to use. Internet connections that use a proxy server or firewall typically do not work.
If the microphone can record sounds into the computer, then it is capable of working with software that carries voice over the internet. Test the microphone to determine if it is functioning properly. If it is functioning properly, then the issue is probably a setting or capability in the chatting software. If it is not working, then use the other sections in this document to resolve the issue.

Fix feedback, noise, and static problems
If microphone boost is selected, noise can interfere with recording. Follow the steps below to check for and disable the microphone boost setting.
  1. Right-click the Sound icon in the system taskbar, beside the clock. Select Recording Devices from the drop-down menu.
  2. When the Sound window opens to the Recording tab, select Microphone , and then Properties . The Microphone Properties window opens.
  3. Select the Advanced tab.
  4. Under Default Format , select the lowest sample rate and bit depth available, such as 2 channel, 16 bit, 48000 Hz (DVD Quality).
  5. Click Close and exit out of all windows.
Try using the microphone again to determine if the problem is resolved.
