The patent in questions covers using a controller device on a LAN which presents a UI to the user to raise, lower or mute/unmute volume which then raises, lowers or mutes/unmutes the volume across a set of speakers grouped together on the LAN. It does not cover a specific method of doing this. Any method accomplishes the above would be covered by the patent.

I feel like "using a UI that communicates over LAN", on it's own, isn't something that should be patentable for anything at this point. That's just basic network communication now. Now, if the device being communicated with did something interesting maybe there is a case on that end, but I'm not familiar enough to comment.
