I've had a look at d-feet and noticed that org.freedesktop.ReserveDevice1.Audio0 and org.freedesktop.ReserveDevice1.Audio1 both look okay,ReserveDevice1 is there. EXCEPT that the object path for both is org.freedesktop.ReserveDevice1.Audio0. In other words, N.B. different dest and path: $ dbus-send --session --print-reply --reply-timeout=2000 --type=method_call --dest=org.freedesktop.ReserveDevice1.Audio1 /org/freedesktop/ReserveDevice1/Audio0 org.freedesktop.DBus.Introspectable.Introspect method return sender=:1.35 -> dest=:1.113 reply_serial=2 string "<!DOCTYPE node PUBLIC "-//freedesktop//DTD D-BUS Object Introspection 1.0//EN" "http://www.freedesktop.org/standards/dbus/1.0/introspect.dtd";> <node> <!-- If you are looking for documentation make sure to check out http://git.0pointer.de/?p=reserve.git;a=blob;f=reserve.txt --> <interface name="org.freedesktop.ReserveDevice1"> <method name="RequestRelease"> <arg name="priority" type="i" direction="in"/> <arg name="result" type="b" direction="out"/> </method> <property name="Priority" type="i" access="read"/> <property name="ApplicationName" type="s" access="read"/> <property name="ApplicationDeviceName" type="s" access="read"/> </interface> <interface name="org.freedesktop.DBus.Properties"> <method name="Get"> <arg name="interface" direction="in" type="s"/> <arg name="property" direction="in" type="s"/> <arg name="value" direction="out" type="v"/> </method> </interface> <interface name="org.freedesktop.DBus.Introspectable"> <method name="Introspect"> <arg name="data" type="s" direction="out"/> </method> </interface></node>" I don't know very much about dbus, but I haven't seen that before. The is pulseaudio-2.1-4.fc18.x86_64, but from the dates in git I don't think the dbus code has been touched in a while. -- imalone http://ibmalone.blogspot.co.uk
