From 7a748af4db17cb0b26d19e5f9939d277128ec94b Mon Sep 17 00:00:00 2001 From: Tanu Kaskinen <tanu.kaskinen@linux.intel.com> Date: Thu, 26 Jun 2014 13:30:25 +0300 Subject: [PATCH 01/14] ucm: Document PlaybackPCMIsDummy and CapturePCMIsDummy values At least PulseAudio needs special handling for dummy devices. To allow that to happen automatically, the UCM configuration should contain the information about which PCMs are dummy.
