However, this module cannot handle 828 correctly to generate sound. The reason is not clear yet.
There is something odd about the 828 - I have observed this with FFADO. While capture works fine, playback remains resolutely muted.
Not resolutely. With this module, in the beginning of packet streaming, the unit can generate sound for quite a short period.
Currently I have a hypothesis that this issue comes from missing synchronization on a path between PDI 1394L21BE and QuickLogic DA828FW. As the name implies, the latter IC is designed by S&S research Inc. just for this unit, and there's less information.
Don't behave with your over-generalization, if being a reasonable person.
