ALSA: Interleaved & non-interleaved?

Prasant J

Hi,

I want to cross check my understanding regarding the ALSA's non-interleaved access method.

What I understand is that when one accesses in non-interleaved mode, then ALSA will receive buffers for all channels and make them interleaved before sending out?
Am I correct?

Or non-interleaved means that the data will be sent out in non-interleaved manner as application writes to alsa-lib?

Hi, Pj,

Is there a particular TI product that you are working with?

Pj,

OK, I am going to move your post to the AM335x forum then.

Sorry about posting this in the wrong thread. D2, thanks for moving to the correct place now!

I had posted the same question on the alsa-devel mailing list and got the reply from them. Here's the link:
