virtio-sound-pci and virtio-sound-device were recently introduced
in QEMU 8.2.0.
The full documentation of the virtio sound implementation in QEMU
can be found here:
https://www.qemu.org/docs/master/system/devices/virtio-snd.html
Example:
<sound model='virtio' streams='2'/>
[Changes in v2]
- Added missing break statement that went overlooked.

New subject: [PATCH v2 2/3] conf: Introduce support for virtio-sound devices
This patch adds parsing of the virtio sound model, along with parsing
of virtio options and PCI/virtio-mmio address assignment.
A new 'streams' attribute is added for configuring number of PCM streams
(default is 2) in virtio sound devices. QEMU additionally has jacks and chmaps
parameters but these are currently stubbed, hence they are excluded in this
patch series.

Allow generation of command line for virtio-sound-pci and virtio-sound-device

A new testcase is added to test virtio-sound-pci. The
arm-vexpressa9-virtio testcase is also extended to test virtio-sound-device.

virtio-sound-pci and virtio-sound-device were recently introduced
in QEMU 8.2.0.
The full documentation of the virtio sound implementation in QEMU
can be found here:
https://www.qemu.org/docs/master/system/devices/virtio-snd.html
Example:
<sound model='virtio' streams='2'/>
[Changes in v2]
- Added missing break statement that went overlooked.

qemu_capabilities: Add QEMU_CAPS_DEVICE_VIRTIO_SOUND capability
