For a full history of the problem please refer to http://subversion.ffado.org/ticket/250 Unfortunately the original reporter no longer has access to the hardware concerned and the report itself dates from 2 years ago (I kept forgetting to report it). However, it may be useful none-the-less. Please CC me any replies. Thanks jonathan
