This is what irritates me the most: If I change the settings (e.g.
setting frames/period to 512) I get exactly the same constant behaviour:
14:31:09.787 XRUN callback (1).
14:31:22.482 XRUN callback (2).
14:31:26.495 XRUN callback (3).
14:31:29.025 XRUN callback (4).
14:31:30.185 XRUN callback (5).

The driver "firewire" does not have a -S option. ffado svn:
