Section: File Formats (5)
The PulseAudio client library reads configuration directives from a file ~/.config/pulse/client.conf on startup and when that file doesn't exist from /etc/pulse/client.conf.
The configuration file is a simple collection of variable declarations. If the configuration file parser encounters either ; or # it ignores the rest of the line until its end.
:default-sink= The default sink to connect to. If specified overwrites the setting in the daemon. The environment variable $PULSE_SINK however takes precedence.
:default-source= The default source to connect to. If specified overwrites the setting in the daemon. The environment variable $PULSE_SOURCE however takes precedence.
:default-server= The default sever to connect to. The environment variable $PULSE_SERVER takes precedence.
:autospawn= Autospawn a PulseAudio daemon when needed. Takes a boolean value, defaults to yes.
:daemon-binary= Path to the PulseAudio daemon to run when autospawning. Defaults to a path configured at compile time.
:extra-arguments= Extra arguments to pass to the PulseAudio daemon when autospawning. Defaults to --log-target=syslog
:cookie-file= Specify the path to the PulseAudio authentication cookie. Defaults to ~/.config/pulse/cookie.
:enable-shm= Enable data transfer via POSIX shared memory. Takes a boolean argument, defaults to yes.
:shm-size-bytes= Sets the shared memory segment size for clients, in bytes. If left unspecified or is set to 0 it will default to some system-specific default, usually 64 MiB. Please note that usually there is no need to change this value, unless you are running an OS kernel that does not do memory overcommit.
:auto-connect-localhost= Automatically try to connect to localhost via IP. Enabling this is a potential security hole since connections are only authenticated one-way and a rogue server might hence fool a client into sending it its private (e.g. VoIP call) data. This was enabled by default on PulseAudio version 0.9.21 and older. Defaults to no.
:auto-connect-display= Automatically try to connect to the host X11's $DISPLAY variable is set to. The same security issues apply as to auto-connect-localhost=. Defaults to no.
