From c75c5ab575af7db707689cdbb5a5c458e9a034bb Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Sat, 27 Apr 2013 12:10:32 +0200 Subject: ALSA: USB: adjust for changed 3.8 USB API The recent changes in the USB API ("implement new semantics for URB_ISO_ASAP") made the former meaning of the URB_ISO_ASAP flag the default, and changed this flag to mean that URBs can be delayed. This is not the behaviour wanted by any of the audio drivers because it leads to discontinuous playback with very small period sizes. Therefore, our URBs need to be submitted without this flag.
