When PulseAudio runs in the per-user mode and detects a login -+ session, then any positive value will be reset to 0 so that PulseAudio -+ will terminate immediately on logout. A positive value therefore has -+ effect only in environments where there's no support for login session -+ tracking. A negative value can still be used to disable any automatic -+ exit.
-+ -+When PulseAudio runs in the system mode, automatic exit is always -+ disabled, so this option does nothing.
