Microphone does not work with network messaging software (chat, online game, and virtual meeting software)
This document applies to HP and Compaq computers with Windows 7.
This document provides solutions to a variety of problems that can occur when using microphones and other line-in sources such as digital audio players, portable disc players, and other types of sound devices.
NOTE:Make sure Windows can produce sounds from the speakers before using this article. If the computer cannot play any sound from the speakers, see one of the following support documents:
Resolving most types of common microphone/line-in problems
Use the following steps to test, check hardware and connections, update audio drivers, and configure Windows sound settings. If you follow these steps in proper order, you will fix the problem or you will find that the audio software needs to be configured or updated.
Step 1: Testing for an audio signal
Use this process to find out if Windows can detect an audio signal from the microphone or from the line-in port.
NOTE:If you are testing the line-in port, and if the source device has a volume control, turning the volume up too high on the source device can cause distortion and might damage the audio hardware. Start with the volume low and slowly turn it up until recording is at the desired level. Never turn up the volume more than half way on the source device.
- Click Start , and then click Control Panel .
- Click Hardware and Sounds , and then click Managing audio devices .A Sound window opens.
- Click the Recording tab.
- To test the microphone, speak into it. To test line-in, send a signal to the line-in port from the source audio device (press play from the audio player). Look at the gray bars next to the device name on the recording tab:
- If the gray bars next to the device name change to green, this device is active and an audio signal is passing through the microphone or line-in port. This step shows that the problem is related to sound settings in the software that uses the microphone. If you have not already done so, set the selected device to default and adjust the volume levels as shown in Step 3 . When the device is set to default and the levels are set, use and adjust the sound recording or voice carrying software.
- If the gray bars remain gray and inactive, the device is not recognizing a signal. Leave the recording tab open and go to the next step.
Step 2: Checking connections and hardware
Try each of the following connection tips, if they apply to your situation, to correct issues involving microphone connections:
- Connect the microphone (or the source device used for line-in) into another computer or audio device. For example, to check a microphone you can plug the microphone into a tape recorder. If the tape recorder can record sound, the microphone and cable are good. If a microphone or source device does not work with another audio device, replace it.
- Disconnect and reconnect the plug. Even if the plug was already connected to the correct connector, reconnecting might help if there is a connection problem between the plug and socket.
- If you are using a USB microphone, try a different USB connector. If the USB microphone came with software, make sure it is installed properly and is compatible with Windows 7.
- Know and use the correct microphone connector on your computer when connecting the microphone to the computer.Desktop PCs
- The microphone connector is usually pink.
- The line-in connector is usually blue.
There are two types of connectors on HP computers for headphones. One supports only sound to the headphones, and the other supports sound to the headphones and the use of a microphone . The connectors are marked with symbols next to them.
- Connectors on the computer marked with a headset with a microphone, , support sound and the use of a microphone when used with a headset with a four-pin plug and a microphone.Figure 4: Four-pin plugTo use the microphone and hear sound from the computer, the four-pin plug and four pin connector must be used .Using a four-pin plug that is capable of supporting a microphone in a three-pin connector allows sound to be heard, but the microphone does not work because the computer's three-pin connector does not support a microphone.
Step 3: Checking volume and mute settings
The speaker volume for the microphone and line-in might be muted or turned down. Use the following steps to check the speaker volume levels for line-in and microphone:
- Unplug all headphones or audio devices before starting.
- Click Start , and then click Control Panel .Control Panel opens.
- Click Hardware and Sound .Hardware and Sound opens.
- Click Sound .The Sound window opens.
- Select Speakers , and then click Properties .The Speakers Properties window opens.
- Click the Levels tab.
- Click the Muted button next to Microphone and any other line-in that is muted.
- Use the slider bar to raise the level for Microphone and each line-in to at least 75.
- Click OK .
Step 4: Using Windows 7 Automated Troubleshooting
The troubleshooting tool in Windows 7 can automatically fix common problems with your computer, such as audio recording. Although it may not fix every problem, it is useful to run the Troubleshooting tool first before you manually correct problems.
To use the Troubleshooting tool:
- Click Start , enter troubleshooting in the search field and select Troubleshooting from the list.
- Under Hardware and Sound, click Troubleshoot audio recording and then click Next when the Recording Audio window opens.
- Select the device you would like to troubleshoot and then click Next .
If a recommended action displays, select Apply this fix or Skip this step to continue to search for other problems. If your problem has not been resolved, continue to manually troubleshoot using the rest of this document.
Step 5: Checking the audio drivers
You might find that a front microphone port does not work, a recording device is missing from the recording tab, a microphone is not recognized when it is plugged in, or other problem. There might be updated audio drivers that can fix these types of issues.
Use the following steps to make sure audio drivers are up to date:
- Connect to the Internet.
- Click Start , and type device manager in the Start search field.A Device Manager window opens.
- Double-click Sound, video and game controllers .
- Right-click the name of the sound hardware and select Update Driver Software... .
- Click Search automatically for updated driver software and wait for Windows to update the driver software.
- Windows checks a remote Web site to see if updated driver software is available.
- If an update is available, let Windows install the update.
- If an update is not available, skip to the next step.
- When the update is installed successfully, test the microphone or line-in as was done in step 1. If the problem persists, go to the next step.
Step 6: Configuring Windows recording settings
By default, Windows 7 automatically enables microphones and line-in ports. Use the following steps to set the microphone/line-in port to be the default port and to configure the recording levels:
- If the Recording tab in the sound window is not selected, open the Sound window and click the Recording tab using the instructions in Step 1.NOTE:Your desktop or notebook PC configuration may include different components then shown here.
- If multiple microphones or line-in ports are available, select the port that you want to use. Click Set Default to make this device the default audio input device.
- If the device you want to use contains a small circle with an arrow pointing down, the device is disabled. To enable the device, right-click the device name and select Enable .
- With the device selected, click Properties , and then click the Levels tab.
- Adjust the slider to 75.
- If Mute is on, click the mute button to un-mate the device. The mute button should show as a blue speaker without a red circle .
- If Microphone Boost is available, adjust to +20.0 dB.
- Click OK to make the changes.
- Test the microphone using the instructions in Step 1 to determine if Windows is able to detect a signal for the microphone or line-in being used. If you have performed all the steps and the microphone or source device still does not work, the audio ports or sound hardware on the computer might be bad.
Microphone does not work with network messaging software (chat, online game, and virtual meeting software)
If the microphone works in Windows, but does not work with a specific software application, such as Internet chat software, the most likely cause is that the microphone needs to be selected and configured in the software application. For example, in many versions of Windows Live Messenger, once you are logged in, you can select tools and then Audio and Video Setup to access a window that allows you to select your microphone from a list of audio input devices. Other popular software titles, such as Skype and Yahoo Messenger have similar settings. Look for sound and audio setup options in the software you want to use to select your microphone.
If the microphone is selected and configured in your software and it does not work, updating the audio drivers or the Internet messaging software may resolve this problem.
Microphone fails after a Web camera or a USB microphone is installed
To use the microphone on a Web camera or a USB microphone, it might need to be configured separately using the software that came with the device. Make sure the USB device and any associated software is compatible with Windows 7. If you want to use a different microphone than the USB microphone or Web camera, select the default microphone that Windows will use. For more information on how to set a default microphone, use Step 6: Configuring Windows recording settings section in this document. Refer to the support Web site of the manufacturer of the Web camera or USB microphone for more information.
