type stopsounds in console to turn off music. A configuration option will be added in the next update.
Also the reason why the ambient music cannot be controlled via the "music volume" slider in the options menu, is because Garry's Mod does not have proper support to play sounds via the music channel. Because of that i have to have the ambient music play through the "game sounds" channel instead.
