I've checked the sources and no, it's not the case. Alsa OSS plugin doesn't use mmap. On the other hand, I see that we do quite heavy patching to its native version (audio/alsa-plugins/files/patch-alsa-plugins). It's quite possible that the same patches (or at least a portion of them) are needed for the linux version to fix audio recording through the plugin. -- Andriy Gapon
