RE: [virtio-dev] Would there be virtio-audio spec in future for clean audio interface

["Tian, Kevin" <kevin.tian@intel.com>]

CC acrn community.

acrn project, as required in automotive/embedded usages. I know they 
have plan to upstream those bits, and now might be a good time to talk
about the plan. :-)

Thanks
Kevin
