Subject: Re: [virtio-dev] Re: [PATCH v8] virtio-snd: add virtio sound device specification

This patch proposes virtio specification for a new virtio sound device,
that may be useful in case when having audio is required but a device
passthrough or emulation is not an option.

v7->v8 changes:
1. Add a universal control request to query information about any
    configuration item (jacks, streams and channel maps). The request
    allows to get information in one by one or in a batch manner.
2. Add a common information header that allows to link items together
    in a unified way.
3. Rework a jack configuration as a jack information structure.
4. Rework a stream configuration as a stream information structure.
5. Make a channel map as a separate item and add the
    "Channel Map Control Messages" section.

Looks good to me.  The new *INFO commands are certainly an improvement.
I guess you have both guest and host implementations for this meanwhile?

Yes, we do. The driver (v8) is available at the same place:

take care,
