A safer option is the single thread access if you want your app to support many different systems including old ALSA.

Anyway, checking with the latest version is helpful for us ;) thanks, Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
