Ah great thanks for reminding, we actually do that, so we don't load from userspace all the time. That was done to get good latency and avoid 50ms ish time it used to load the firmware. see sst_cache_and_parse_fw() so dev_info_once() would suffice here -- ~Vinod _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
