As a response to my lastest article about Streaming audio with MPD and Icecast2 on Raspberry Pi, I was asked for some ideas about live streaming. I took the chance to plug in an usb audio device with microphone to RasPi and tried to get it working.
The first models of Raspberry Pi computers were shipped and I was happy to receive one this week. RasPi is a SoC computer for ~25€ with Broadcom BCM2835 (ARM) CPU, 256MB, Ethernet, USB, HDMI and 3.5mm audio jack. I completed the equipment with an additional wireless USB adapter. Let me describe how to I managed to get the device working. !!!! UPDATE (2012/07/22) I recommend to use the raspbian image with a prebuild wireless module working out of the box.
