... ALC886 SPDIF input. The test results show that the input is not "source synchronous"
It seams that my HDA clock is a bit slower then definition ( about -10ppm) Therefore resampling starts below -10ppm It probably means that when spdif signal is 0ppm, about 10ppm of samples are missing.
And real S/PDIF inputs probably are all over the map ...
Is this a bug? or it is planed like this?
The HDA specification describes source synchronous streams, but does not mandate them.
Apparently, the ALC886 does not support source synchronous streams. A quick Google search shows only the WM8850 (which also has a real sample rate converter).
