this is just to bring the story to it's end: after finding the patience to read all the valuable hints on ffado.org and doing some tweaking I now have a fine and stable running system - the Focusrite Saffire Pro10 is really a great deal. Also the IRQ-sharing issue is solved by disabling the NVIDIA driver. Thanks a lot again for all your comments, Susanne _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
