In QEMU, the card itself is a PCI device, but it requires a codec (either -device hda-output or -device hda-duplex) to actually output sound. We set up an hda-duplex codec by default: I think it's important that a simple <sound model='ich6'/> sets up a useful codec, to have consistent behavior with all other sound cards. This is basically Dan's proposal of <sound model='ich6'> <codec type='output' slot='0'/> <codec type='duplex' slot='3'/> </sound> without the codec bits implemented. The important thing is to keep a consistent API here, we don't want some <sound> models to require tweaking codecs but not others. Steps I see to accomplishing this when someone gets around to it: - every <sound> device has a <codec type='default'/> (unless codecs are manually specified) - <codec type='none'/> is required to specify 'no codecs' - new audio settings like mic=on|off could then be exposed in <sound> or <codec> in a consistent manner for all sound models Signed-off-by: Cole Robinson <crobinso(a)redhat.com&gt; --- 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 | 24 ++++++++++++++++--- .../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, 31 insertions(+), 9 deletions(-) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index e9fcea1..b9b83c2 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.
