There are several in the Amazon Appstore, but I’ve been using ES File Manager. The APK files can be emailed to the device, and downloaded from the native email client, then installed from any file manager. Those without another Android device might consider asking around on forums for users to extract the files for them. Anyone with an Android phone can download an app from the Android Market and extract the installation package, known as the APK, using apps like Astro File Explorer. This can be a risky proposition as malware is more common in this kind of gray market space. Some Android apps can be obtained from their developer’s site, or from various alternative repositories online. Under Device, there is a toggle to allow the installation of apps from “Unknown Sources.” That needs to be set to “On.” Once the device is ready to go, you need to find the apps. If the volume is fine, double-check the menu next to Speakers and see if there's another option to pick from, and then try the sample sound again.To install apps from outside Amazon’s ecosystem, one need only to take a quick trip into the settings.If you don't hear anything when you play the sample sound, make sure your speakers or headphones are turned all the way up (some headphones have physical volume buttons) and that the on-screen settings are at 10.You should hear sound in your headset or speakers. To check the sound in Skype to make sure that it's using the right speakers, select Test audio under the Speakers option.

Finally, unplug the microphone and then reattach it. If there aren't other ones to pick from, make sure the microphone is plugged in, powered on (if it has a power switch), and has batteries (if wireless).If the microphone doesn't work with Skype, select the menu next to Microphone and see if there are any other options you might have the wrong device selected.As you talk, you should see the bar light up. With that setting open, notice the volume area under Microphone.
