Well, this is simply because I haven't supposed that the async interface is ever used by such apps. The async feature is pretty system-specific and it wouldn't work with the strict POSIX implementation. It practically works right now, though :) So, I'm pretty open for any implementation of this if the user-space driver can provide any functionality. Most likely we need to add a new callback, so the ABI would change. But, as long as the backward compatibility is kept, I'm for any addition. thanks, Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
