Raspberry Pi - Intercom

A wireless, configurable software driven intercom for the house sounds great. Here on this page, I’ve listed out a number of the steps that I took to transform my Raspberry Pi into an intercom where I could communicate from my PC to the PI in real-time. Unfortunately, the USB audio card attached to my PI that provides a jack to connect a mic, did not provide very good quality back to the PC. I tried to modify the sampling rate, but didn’t have much luck. Here are the setup steps and commands that I used.

• sudo raspi-config
• sudo rpi-update
• sudo apt-get install lynx screen festival ffmpeg libjpeg8-dev imagemagick subversion libjpeg8-dev mplayer libasound2-dev bison python-dev python2.7-dev python python-alsaaudio linphone python-dev python-rpi.gpio tightvncserver
• tightvncpasswd
• tightvncserver
• #Connect to VNC server from the other machine. Type mumble. Choose the ALSA audio card instead of Pulse.
• linphonec -C
• sudo apt-get update
• sudo dpkg-reconfigure mumble-server
• sudo modprobe snd_bcm2835
