Windows 8 Microphone Settings Explained

Understanding Windows 8 microphone settings is important when troubleshooting audio input problems.

Key settings include:

Recording Devices	Selects microphone input
Microphone Levels	Adjusts input volume
Microphone Boost	Amplifies microphone signal
Default Device	Sets the active microphone

If your microphone seems too quiet, adjusting these microphone levels in Windows settings can resolve the issue.

Microphone Too Quiet Windows—How to Increase Volume

If your microphone is too quiet and the Windows issue persists, increasing microphone sensitivity is necessary.

Increase Microphone Sensitivity

1. Open Windows Sound Control Panel
2. Select Recording Devices
3. Double-click your microphone
4. Increase Microphone Boost

Typical settings:

Boost Level	Effect
+10 dB	Small increase
+20 dB	Moderate increase
+30 dB	Maximum sensitivity

This setting improves microphone volume and Windows performance.

Many a time you buy a new headset but face different software and hardware challenges. Recently I bought a “Creative HS-330” headset. But the mic volume was very low. Though the headphone audio quality was excellent, I was unable to record any videos due to this issue. The OS was Windows 8.1. I had a dual-boot scenario, so I tested in both the 32-bit and 64-bit versions.

However, the recorded volume through the mic remained low. I was getting my sound through VIA High Definition Audio drivers. Though the “playback” sound was excellent, I still had to find a way to fix the mic issue, which was affecting my ability to communicate clearly during calls and recordings. Since I bought the headset from “SnapDeal.com,” I could have returned it. But for the price of Rs 449, I thought the model was a decent headset, as per the reviews on the site.

So then I toyed with the options in the Control Panel.

I double-clicked the “Sound” item, which allows us to configure audio devices or change the sound theme on our operating system. In the pop-up window, you see different tabs like

1. Playback
2. Recording
3. Sounds
4. Communications

To troubleshoot the “mic volume too low” problem, we need to go to the Recording tab. Select the right “microphone” device (if you have multiple devices). You generally see a “green tick mark” to see which one works. Then click on the “Properties” button on the same tab.

Then you’ll get another pop-up window, with further options in tabs. These include

1. General
2. Listen
3. Levels
4. MicArray
5. Advanced

On the “General” tab, if you click the “Properties” button, you’ll know about the VIA High Definition Audio Properties. Under the “Driver” tab you can see several other properties. Just make sure that the “Driver version” is at least 6.0.1.10800. If you have an obsolete driver, you can download the latest driver from the Internet.

Fix #1

On the “Levels” tab, you can change both the options. These are

1. Microphone
2. Microphone Boost.

Setting the values to maximum generally increases the mic volume. On my computer, the values are “100” and “+30.0” dB, respectively. One thing to understand is that the adjustment is kind of a software fix. If your mic volume is fine, you should hear recorded volume with your headset. Also, increasing the “Microphone Boost” value, which amplifies the microphone’s sensitivity, will make you hear “disturbances” and “outside noise.” But this adjustment is one fix for low mic volume.

Certain types of hardware and software show the “Microphone Boost” as a custom option.

Fix #2

On the “MicArray” tab, you can change the value of “Conference Mode” to full volume. This adjustment fixed the problem in my case. But when I rebooted, the problem was there again. Also, DO NOT USE other effects with this device. These include—

Single User Mode

• Enable Echo Cancellation
• Enable Beamforming
• Enable Noise Suppression

Using any of the above effects actually reduced the mic volume in my case.

Fix #3

On the “Advanced” tab, you can change the values for “Default Format” and “Exclusive Mode.” In my experience, I didn’t find any difference in mic volume by changing these values. But on different forums, I found that toying with options solved some of the user mic problems.

If you are using an “Analog” mic, then you can set the “Default Format” to “2 channel, 16 bit, 48000 Hz (DVD Quality).” Regarding the “Exclusive mode,” you can UNCHECK the following options.

1. Allow applications to take exclusive control of this device
2. Give exclusive mode applications priority.

By doing so, some users were able to solve their problem.

If there is no change in mic volume by doing this, you can CHECK these options. Just do a trial and error. This is because different brand headsets have different resolutions to this problem, such as varying compatibility with devices or differing sound processing capabilities.

Fix #4

Generally, the above fixes should solve your problem. But if you are still unable to hear your voice back, then you can go to the “Communications” tab in the “Sound” window.

Here, the default option is “Reduce the volume of other sounds by 80%.” You can check the option that says “Do nothing” and click on the “Apply” button.

Fix #5

If you have more than 1 mic, you can disable all the rest of the devices. Just have one device enabled, and that should work properly.

Fix #6

If you have an “analog” mic, i.e., with “jack”-kind of pins, you should be having this problem. It would be advisable to consider purchasing a headset with a USB feature. Since Windows 8.1 is a new OS, it is more compatible with new hardware. So if you are planning to buy a mic, better stick to a USB one.

Fix #7

As found in this post, your answer could lie in adding a “microphone preamplifier” to the current setup.

In some cases, like your issue, the analog microphone needs to be amplified by a microphone preamplifier, as some computers’ mic inputs do not give enough voltage to the microphone. Microphone preamps are small devices that connect your mic to your PC or laptop. You can find plenty of mic preamps in the musical instrument stores or online with reasonable prices.

Fix #8

If you are having the problem of mic volume being too low on Skype, then you can try the above fixes as well. Then you can do an additional setting that is inherent to Skype. You can go to Tools > Options > Audio Settings. There you can UNCHECK the option that says “Automatically adjust microphone settings.” This option will be available under the “Microphone” setting on the right-hand side. Then you can increase the “Volume” slider to a higher side.

If you have made the above fixes, then it must have already been on the higher side.

You should make this change only when the user on the other side receives low sound when you are talking on your mic. Otherwise, just leave it to the default option.

Miscellaneous Fixes

You can also try a few things like installing new drivers for your chipset and audio drivers and updating Windows 7, 8, or 8.1. You can also try to install the old drivers that came with the CD of your motherboard. You can also unplug all speaker jacks and just keep the mic in.
