[alsa-devel] WRITING AN SOC DRIVER WITHOUT DMA

[dinesh]

Hi,
I think no one is able to understand my problem, let me break it to low
level.
What i want is that i have a buffer in driver code which is also handled
by some other application i want that this buffer data is to be used for
capture and playback  stream fills data to another buffer which i can
passover to my other application.
If someone can help me please.
Regards,
Dinesh

Hi dinesh,

If you are working on ARM, see the ARM AACi code, in sound/arm/aaci.c

Thanks
