In QEMU, the card itself is a PCI device, but it requires -device hda-output in order to actually get sound to the host. AIUI this is just HDA configuration and does not require stable addressing, so is not presently represented in the XML. Additionally, qemu supports audio input with '-device hda-duplex', however that provides guests access to the host's microphone, so probably isn't what we want by default. --- docs/formatdomain.html.in | 5 +++-- docs/schemas/domain.rng | 1 + src/conf/domain_conf.c | 3 ++- src/conf/domain_conf.h | 1 + src/qemu/qemu_command.c | 14 +++++++++++++- .../qemuxml2argv-sound-device.args | 2 +- .../qemuxml2argvdata/qemuxml2argv-sound-device.xml | 1 + tests/qemuxml2argvdata/qemuxml2argv-sound.args | 2 +- tests/qemuxml2argvdata/qemuxml2argv-sound.xml | 1 + 9 files changed, 24 insertions(+), 6 deletions(-) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index e9fcea1..8c43b74 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -1663,8 +1663,9 @@ qemu-kvm -net nic,model=? /dev/null The <code>sound</code> element has one mandatory attribute, <code>model</code>, which specifies what real sound device is emulated.
