A really helpful tool for playing music though your phone!
Lesser AudioSwitch is an application that allows you to change the audio outputs of your mobile device, including speakers, headphones and earphones, microphone, and USB and Bluetooth devices.
This app is especially useful for instances when your smartphone is unable to detect your headphones, or if the the audio connection fails for whatever reason. It is also handy if your want to customise how you want your device to interact with audio. For example, if you want it to detect when you plug in a headset or speaker. You can even force the sound to continue playing through the speakers even with headphones connected.
Lesser AudioSwitch also includes a widget that allows you to change the audio inputs with a single touch from the home screen, and in the settings you can activate a permanent notification that allows you to switch from one to another with a simple touch
