AFAIK there are some undocumented constraints on which configurations and alternate settings can be used; and in some alternate settings, the device uses big-endian samples. This cannot be handled with the generic parts of the uaudio driver; it requires device-specific workarounds. There is an outdated patch that tries to make this device work on Linux on this page: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3249 Regards, Clemens
