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
