AlexT_Intel & CMata_intel: Thanks for your input. It's a hobby robotic project that requires onboard audio capability, and possibly video too. Your suggestion of HTML5/Node.JS is interesting but will not work for it. Adding a USB sound card may be the easiest for audio, but it adds additional cost. For video, do you have detail instructions on how to use Alsa, I'm not familiar with it.
Can you suggest another Intel Atom based board that has both audio and video capabilities plus WiFi and Bluetooth 4.0, if Edison is not the right choice? I know Atom chips were used in smartphones and tablets, so it must be able to do these things. I appreciate any recommendations.
