The final command acknowledgment value for the group "Mics" is the value returned from the first member
of the virtual channel group "Mics".
It is possible to have multiple virtual channel groups that include the same virtual channels. Commands sent
to the particular virtual channel group affect the members of the group and all members of the group respond
with the appropriate command acknowledgments.
Note: Virtual Channels Include in Multiple Groups
Multiple virtual channel groups may include the same virtual channels, in other
words, a virtual channel can belong to more than one virtual channel group.
