[alsa-devel] Interleaving and Deinterleaving support
Hi,
Does alsa core in the kernel support interleaving and deinterleaving? if the driver receives a deinterleaved stream and wants to interleave for the sound card, should the driver perform the conversion?
Cheers,
Sing

No, but the alsa-lib plugins can do this.

No, the driver should just set the bit that indicates that the hardware supports interleaved data; the data will then be automatically converted by alsa-lib.
