I Bus 002 Device 003: ID 0d8c:000c C-Media Electronics, Inc. Audio Adapter I had a centos box worked fine. I disabled the on board audio. put my usb device in and it is behaving the same way. plays wave files but asterisk dies. I have been searching for a know issue on this or fix but have not found one yet. Any help is appreciated.
