 \fBlocal-server-type=\f1 Please don't use this option if you don't have to! This option is currently only useful when you want D-Bus clients to use a remote server. This option may be removed in future versions. If you only want to run PulseAudio in the system mode, use the \fBsystem-instance\f1 option. This option takes one of \fBuser\f1, \fBsystem\f1 or \fBnone\f1 as the argument. This is essentially a duplicate for the \fBsystem-instance\f1 option. The difference is the \fBnone\f1 option, which is useful when you want to use a remote server with D-Bus clients. If both this and \fBsystem-instance\f1 are defined, this option takes precedence. Defaults to whatever the \fBsystem-instance\f1 is set.

 Do not install CPU load limiter on platforms that support it. By default, PulseAudio will terminate itself when it notices that it takes up too much CPU time. This is useful as a protection against system lockups when real-time scheduling is used (see below). Disabling this mechanism is useful when debugging PulseAudio with tools like \fBvalgrind(1)\f1 which slow down execution.
