Testing your equipment
To troubleshoot microphone or line-in recording problems, make sure the microphone works and that the computer is able to record sound:
Testing the microphone
Make sure the microphone is functional by connecting it to a recording device such as a tape recorder. Record your voice into the recording device using the PC microphone. If the microphone successfully records your voice, test the microphone in the PC again. If a recording device is not available, try another microphone in the PC that is known to be good.

Testing the line-in audio source
Make sure the device that you are trying to receive an audio signal from (tape player, record player) is sending a good audio signal by connecting it into another playback device other than the PC, such as a tape recorder, home stereo system, or another PC that is known to have the line-in working properly.
If another playback device cannot detect or play the audio signal, the problem is probably coming from the device sending the audio signal. Troubleshoot or try a different the audio device to get a better audio signal for your line-in on the PC.

Testing the microphone record function on the PC

Plug the microphone into the mic-in plug on the PC .
In Windows XP: Click Start, All Programs, Accessories, Entertainment and select Sound Recorder.
In Windows 98 & Me: Click Start, All Programs, Accessories,Entertainment and select Sound Recorder.
Click Record (the red circle) and speak into the microphone.

The thin green line should move as you speak into the microphone.
When finished recording, click Stop (the black rectangle).

To play back the recorded sound click Play (the single black triangle).

If the recorded sound does not play back, continue to the next section of this document.

No sound is recorded (recordings are silent)
If, when recording with a microphone, no sound or signal is recorded, complete the following steps to resolve this issue.
Step 1: Checking connections

Verify the microphone or line-in source is plugged into the correct jack on the PC. The microphone connector is usually pink (or yellow), and the line-in connector is usually blue:

If you are attempting to record sound from an audio device using the line-in connector, make sure that the volume on the audio device is not muted, or the volume on the device is not set too low.

NOTE: Turning the volume up too high on the source device can cause distortion and may cause damage to the PC line-in jack. Start with the volume low, and slowly turn it up until the recording is at the desired level.
If you are using a microphone and it is connected to the correct jack and there is still no sound, try unplugging the connector about 1mm (1/32th inch), so that the connector is sitting more loose in the connector. It is possible your microphone’s connector does not match up correctly with the connector on the sound card. If this does not resolve the problem, push the connector firmly into the connector and continue with these steps.
If you are using a USB microphone try a different USB connector. If the microphone came with software, make sure it is installed properly.
If the problem continues, go to the next step.

Step 2: Checking Windows settings

Click Start, Programs, Accessories, Entertainment, and Volume Control.
A Volume Control or Master Volume window appears.
Click Options, and then Properties.

Select Recording, and make sure Microphone, Mic Volume or Line-In is selected.

Click OK.
The Volume Control Window should change to a Recording Control or Recording Gain Control window.
Click Options and Advanced Controls. If an Alternate Microphone is not available, continue to Step 3.
Remove the checkmark next to Alternate Microphone, if it is available, click Close, and test. If there is still no sound, continue to the next Step.


Step 3: Selecting correct recording device

In Windows XP, click Start, and then Control Panel.
In Windows 95, 98, and Me, click Start, Settings and Control Panel.
In Windows XP, click Sounds, Speech, and Audio Devices, and then Sounds and Audio Devices.
In Windows 95, 98, and Me, double-click Sounds and Multimedia or Multimedia.
Click the Audio tab.
Under Sound Playback, select the Audio device that is installed on the PC.
Under Sound Recording, select the Audio device that is installed on the computer.
Click OK.
Close the Sound and Multimedia Properties window and test the recording. If there is still no sound, continue to the next Step.

Step 4: Removing duplicate Soundcard entries from Device Manager

Start the computer in Safe Mode:
Turn on the computer and when the blue HP screen appears, press the F8 key repeatedly.
Use the Up and Down arrow keys to select Safe Mode and press the ENTER key.
If a "Please select the operating system to start" menu appears, select “Windows XP Home Edition” (or similar).

In Windows XP, click Start, right-click My Computer, and select Properties.
In Windows 95, 98, and Me, right-click My Computer, and then select Properties.
In Windows XP, click the Hardware tab and then the Device Manager button.
In Windows 95, 98, and Me, click the Device Manager tab and select View devices by type.
Click the plus (+) sign next to the Sound, video and game controllers icon from the list and check if there are soundcard entries that have the exact same name.
Select each item one by one, clicking Remove, and then OK each time. Continue removing sound devices in this way and on as many devices as possible. Windows does not allow some devices to be removed. Skip these devices and continue with the remaining entries in the list unitl all possible devices have been removed.
Restart the PC and let the system detect and install the sound card drivers again. Try recording again to see if the problem is resolved.

Microphone does not work with Internet software (Chat rooms)
There are many reasons why voice may not work over the Internet. These reasons vary based on the voice software you are using. Typically, Internet connections that use a proxy server or firewall do not work.
If the microphone can record sounds into the PC, then it is capable of working with software that carries voice over the Internet. Test the microphone to see if it works. If the microphone can record, then use the online help for the voice carrying software that you are using.

Microphone fails after Web camera is installed
Some Web cameras include a built-in microphone. Windows may have problems determining which microphone it should use when a Web Camera is installed on the PC. To use the microphone on the Web camera, it may need to be configured separately in the Web camera software. If you want to use a different microphone than the one included with the Web camera, the Web camera microphone may need to be disabled. Refer to the documentation that came with the Web camera or consult the Web site of the manufacturer of the Web camera for more information.

Fixing feedback, noise, and static problems
If the Microphone Boost feature is enabled, noise can interfere with recording. Use the following steps to check for and disable the Microphone Boost feature:

In Windows XP, click Start, and then Control Panel.
In Windows 95, 98, and Me, click Start, Settings, and Control Panel.
In Windows XP, click Sounds, Speech, and Audio Devices, and then Sounds and Audio Devices.
In Windows 95, 98, and Me, double-click Sounds and Multimedia or Multimedia.
Click the Voice tab.
Click Volume inside Voice Recording or Voice Capture.
Click Advanced inside the Balance adjustment for the microphone. If the Advanced option window does not display, select Options and click Advanced Controls (Advanced Controls may not be available on some models).
In Advanced Controls for Microphone, select 1 Microphone Boost or +20dB Gain.
Click Close and close all Windows. Try recording again.
