Introduction

This walks you through routing the microphone's audio to your headphones. I've tested it on a Raspberry PI (Raspbian Jessie).

Introduction

This walks you through installing JACK, connecting a USB sound card, and copying the audio on the input port onto the output port. The result: you will hear what you say played back immediately from the headphones.

Installation

sudo pip install setuptools
sudo apt-get install python-dev

sudo apt-get install libffi-dev

Introduction

This walks you through setting up your Raspberry PI 3 (Raspbian Jessie) as a bluetooth audio receiver.

Credits https://www.raspberrypi.org/forums/viewtopic.php?t=68779. Parts of this tutorial did not work for me, so I'm noting my fixes here. Also, I added instructions for setting up a custom USB sound card for better quality.

Set up USB sound card on Raspberry PI

If you don't need analog audio then prevent the module from loading and set the USB headset as the default device.

Disable analog audio. Open /boot/config.txt and comment out dtparam=audio=on.

Set the USB audio device to the default device. Open /lib/modprobe.d/aliases.conf and comment out the line options snd-usb-audio index=-2

Reboot

Run the command:

cat /etc/os-release

If a module was installed with sudo pip install, the user may not have permissions to access the module,
resulting in 'No module called...' errors.

Quick get around: run py script with sudo

Virtual environments allow you to install dependencies without conflicting with your current installs.

## Installing
[sudo] pip install virtualenv

sudo /usr/bin/easy_install virtualenv
