How can I overcome this limit? It's a recently introduced limit to avoid the too condensed spinlocks that may lead to a kernel lockup (the commit 71321eb3f2d0). If sub-ms timer is really required, we may introduce some module option to allow it, but it's the last-resort. What's the exact use case? thanks, Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
