Description:
|
|
DMA buffers tend to have a alignment requirement for the
|
|
buffers. If this alignment requirement is not met samples might
|
|
be dropped from the buffer.
|
|
|
|
This property reports the alignment requirements in bytes.
|
|
This means that the buffer size in bytes needs to be a integer
|
|
multiple of the number reported by this file.
|
|
|
|
The alignment requirements in number of sample sets will depend
|
|
on the enabled channels and the bytes per channel. This means
|
|
that the alignment requirement in samples sets might change
|
|
depending on which and how many channels are enabled. Whereas
|
|
the alignment requirement reported in bytes by this property
|
|
will remain static and does not depend on which channels are
|
|
enabled.
