roard - RoarAudio sound server
roard is the most common RoarAudio sound server. The RoarAudio sound server is the central component in a RoarAudio setup. It mixes up different audio streams from it's clients to send them to it's outputs. Such outputs include soundcards, monitoring clients, streaming servers and more.
NOTE: This list is incomplete! --help Print some help text. --daemon Go into background after startup. --realtime Ask for higher priority. May be used multiple times. --memlock LEVEL Sets default memory locking level to LEVEL. Valid levels are: none No memory is locked at all. low Only very few (important) objects are locked in memory. medium Few (important) objects are locked in memory. high Many objects are locked in memory. nearlyall All known objects are locked in memory. nearlyallsys All known objects are locked in memory but also pages provided by the system like stack and heap. allcur All currently used pages are locked in memory. all All pages (including future allocated pages) are locked in memory. default Use defaults (the default). A higher memlock level may result in memory allocations problems at runtime and even segfauls on some systems. (VM killed processes). Check your current system limits before altering this value. --watchdog Enable watchdog. This will terminate the daemon if something bad happened and it halted. --watchdog-time TIME Set watchdog time to TIME (in ms). --pidfile PIDFILE Asks the server to use the given pidfile. This is recommended. --sysclocksync Messure exact audio clock frequency based on system time. obsolete.
--location LOC Sets lion-readable location of server. Examples: livingroom, room 32 --description DESC Sets lion-readable description of server. Examples: Stereo, UKW Transmitter --contact CONTACT Sets contact information for the server. --serial SERIAL Sets the serial number for this device or server. This is normally only used by embedded systems. --uiurl UIURL Sets the URL of the user interface for this device or server. This is normally only used by embedded systems. It is common to set this to a URL of type HTTP but all protocols are considered valid. This includes ssh, telnet and others.
STARTUP AND SHUTDOWN
--start Start a new server. --stop Stop the currently running server. See also --shutdown. --restart Stop the currently running server and start up a new server. --shutdown Terminates the currently running server after last client has quit. This is the most clean way to shutdown a running server as it does not kick any clients. This option must not be confused with --terminate. --terminate Auto terminates the new server after last client has quit. This option must not be confused with --shutdown. --script-postdown S Run script S after server shutdown. The script is passed to a shell. Any shell feature can be used within the string.
--standby Start in standby mode. --auto-standby Go into standby mode if no streams are active.
--verbose Increment the verbosity level. Can be used multiple times. --log-syslog Log to syslog.
--plugin-load FILENAME Load the given plugin. --plugin-args ARGS Arguments for the plugin. (must be given before the --plugin-load). --list-plugins List loaded plugins.
--chroot DIR Chroots to the given directory. This improves the security. This normally needs root privileg's.
USER AND GROUPS
--setgid Sets GroupID to the audio group as specified via -G. --setuid Sets UserID to the audio user as specified via -U. -G GROUP Sets the group for the UNIX Domain Socket, (default: audio) You need the permittions to change the GID. -U USER Sets the user for the UNIX Domain Socket, (default: do not set) You need the permittions to change the UID (normally only root has).
The following options control the access rights of connections. Some of them take an access level. The access level is one from the following list: none This is used to disable an authentication method. idented Used internally. Should not be used. conctl The client is only allowed to do some basic operations only affecting it's own connection. guest Guest access (read only). The client may list resources but not alter them. user Normal user. The client may create and alter most resources. pwruser Power User. The client can create and alter all resources and do all operation but operations which would break the POSIX right system. The user is not allowed to control the server itself like terminating it or alter (system) resources with the rights of the user runnung roard. This is the access level a fully trusted user in a multi user setup should have. all The client can do everything. This includes operations which may alter system resources (like files) with the rights of the user running roard. This accesslevel should be given to the user in case of a single user setup or root or some administrator in a multi user setup. --guest-acclev ACCESSLEVEL Sets the access level for guest connections. Set to "none" to disable guest access. --trust-acclev ACCESSLEVEL Sets the access level for clients authenticated by trust auth. Set to "none" to disable trust auth. --trust-root Trust root user. --no-trust-root Do not trust root user. --authfile-gen FILE Generate a new authfile with a fresh cookie. --authfile-load FILE Load all keys from a given authfile. --authfile-type TYPE Sets the type for the authfile. --authfile-acclev ACCLEV Sets the access level for the given authfile. --new-authfile Add another authfile.
--rate RATE, -R RATE Set server sample rate. --bits BITS, -B BITS Set server bits. --chans CHANNELS, -C CHANNELS Set server channels. --aiprofile PROFILE Use a existing audio profile.
GENERAL STREAM OPTIONS
--stream-flags Sets default flags for a given stream directions. Examples: play=-meta, bidir=+antiecho
--list-driver Shows a list of all available drivers. --driver, -d This option is obsolete. Use -o instead. --device, -D This option is obsolete. Use -O instead. --odriver, -o Set the output driver. To get a list of all drivers use --list-driver. --odevice, -O Set the device for the output driver. Possible devices depends on the driver. They may be a path to a device node or a hostname. Use --list-driver to get a hint. -oO Sets options for the new stream. See STREAM OPTIONS. -oN Adds another output. -oP Marks the output primary.
--list-sources List all supported sources. --source, -s Adds a source of the given type. -S Sets the device or filename for the source. Type may depend on the source type. -sO Sets options for the current source. -sN Adds another source. -sP Marks the source as primary. If the source reaches EOF roard will quit automatically.
HARDWARE MIXER OPTIONS

rate Sets the sample rate. channels Sets the number of channels. bits Sets the number of bits per sample. codec Sets the codec. blocks Sets the number of memory blocks that sould be used by the devices. Most devices only support a few values or don't support this option at all. If this option or the specifyed value is not supported by the device this is not handled as fatal error. blocksize Sets the size of the memory blocks used by the device. Most devices only support a few values or don't support this option at all. If this option or the specifyed value is not supported by the device this is not handled as fatal error. meta Sets the meta flag. sync Sets the sync flag. primary Marks this stream as primary. cleanmeta Sets the cleanmeta flag. autoconf Sets the autoconf flag. This flag is not supported by all drivers. If the flag is set and the devices does not support this there is no fatal error if the device could be opend with defaults. Example: rate=44100,bits=16,channels=2,codec=pcm,sync
primary Makes this stream as primary. autoconf Sets the autoconf flag. passmixer Sets the passmixer flag. name Sets the name for the device. subs Sets list of subdevices. This is driver specific.
HOME The users home directory. ROAR_SERVER The address of the listening server. This may be in form of host:port for TCP/IP connections and /path/to/sock for UNIX Domain Sockets. ROAR_DRIVER The driver to select. Same as -d. ROAR_DEVICE The device to select. Same as -D.
There are lots of bugs...
