There are 3 possible values for the "speaker" option: on, off, disabled.
If you disable it server side, the client cannot enable it.

There are many ways of doing this on the client side, you can add:
* "--speaker=off" to you command line, as a one-off.
* "speaker=off" to your connection file if you use one (for that host)
* "speaker=off" to your user settings (affects all connections)
* "speaker=off" to your global xpra settings (affects all users)
* turn it off using the system tray at runtime
