Hi guys!, I am using an iball c8.0 http://www.iball.co.in/Product/Face2Face-C8-0--Rev-3-0-/90 on Raspbian(actually Raspbian Wheezy to be more specific). My lsusb report is , lsusb Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. Bus 001 Device 004: ID 0c45:6340 Microdia I tried using motion software for motion detection and it is working fine. The problem is that I also want to use the inbuilt mic for audio input.
