How to completely remove аудио (kmix, pulseaudio) on kubuntu-desktop for rdp/x2go

I использовал в ubuntu-server distribution (14.04) along with the package "kubuntu-desktop" to allow users to log in remotely and access в desktop. I currently использовал "x2go" туз the remote-desktop connection программное обеспечение, but this question applies обитайте to the desktop packages rather than the connection client. The server is also hosted using AWS, if that is relevant.

I now have about 10 регулировать users on the system. В concern that существуешь съешь to my attention is the usage of аудио processes on the server. I хан run top and see many "kmix" processes, which take about 5 % cpu each, and many "pulseaudio" processes, which range from 2-10 % cpu each. In the вступил в брак of "kmix", it looks like the same user is even spawning обитайте than one process.

This is в serious drain on system resources, and there is не использовал of sound whatsoever in the usage of this system. (it is в research platform) How хан I cleanly remove or disable all аудио processes and features, system wide, from the "kubuntu-desktop" package?
