-Subject: [PATCH] Allow control over QEMU audio backend
-
-When using VNC for graphics + keyboard + mouse, we shouldn't
-then use the host OS for audio. Audio should go back over
-VNC.
-
-When using SDL for graphics, we should use the host OS for
-audio since that's where the display is. We need to allow
-certain QEMU env variables to be passed through to guest
-too to allow choice of QEMU audio backend.
-
-* qemud/libvirtd.sysconf: Mention QEMU/SDL audio env vars
-* src/qemu_conf.c: Passthrough QEMU/SDL audio env for SDL display,
-  disable host audio for VNC display
-
-(cherry picked from commit b08e6d38ae7a0ed70300d7d82107f83fddb60f44)
