Hi,

I'm trying to get working Alsa with the PortAudio library on an embedded 
device (Nokia N810). The problem is that the sound driver is not an 
hardware driver for Alsa but a plugin which deals with the internal DSP 
of the device. This plugin doesn't support mmap'ing at all. So I was 
wondering if it is possible to configure Alsa a way such PortAudio can 
use mmap'ing on my DSP plugin ? I saw there is a mmap_emulation flag but 
the problem is that it seems to be only available on HW driver and not 
on alsa plugins.

Any clues ?

Thank you in advance

Mathieu
