[Spice-devel] [PATCH 2/2] protocol: add SPICE_{PLAYBACK, RECORD}_CAP_VOLUME caps

[Marc-André Lureau]

From: Marc-André Lureau <marcandre.lureau at redhat.com>

These changes the protocol the following way:

When the client announces it has SPICE_PLAYBACK_CAP_VOLUME, the server
can send PlaybackChannel.{volume,mute} messages to notify of volume
changes (respectively for RECORD).

If the client doesn't implement SPICE_PLAYBACK_CAP_VOLUME, the server can
handle the volume changes the way it prefers, for example, ignoring them or
applying volume effect on the server side etc..
