In FS it is in Frame, ie 1ms. Also, the feedback endpoint may be using bRefresh instead of bInterval to determine the interval to check the feedback sample rate. I'm also implementing the async iso OUT with feedback using UAC1 at HS right now so I'm following your posts :-) Alex _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
