pulseaudio @12.99.3_0+x11: autolaunch/dbus not working

[quentinmit (Quentin Smith)]

pulseaudio autolaunch/dbus doesn't work on my machine. When run from Terminal.app, pulseaudio --start just prints:

$ pulseaudio --start -vvvvv
W: [] caps.c: Normally all extra capabilities would be dropped now, but that's impossible because PulseAudio was built without capabilities support.
D: [] conf-parser.c: Parsing configuration file '/opt/local/etc/pulse/client.conf'
D: [] conf-parser.c: /opt/local/etc/pulse/client.conf.d does not exist, ignoring.
E: [] main.c: Daemon startup failed.

When I run it without --start, we find out it's because pulseaudio can't talk to dbus:

$ pulseaudio
W: [] caps.c: Normally all extra capabilities would be dropped now, but that's impossible because PulseAudio was built without capabilities support.

The error doesn't make any sense to me because pulseaudio is definitely not setuid:

$ ls -lh /opt/local/bin/pulseaudio 
-rwxr-xr-x  1 root  admin   101K Sep  5 05:28 /opt/local/bin/pulseaudio

Interestingly, if I run pulseaudio /as myself/ with sudo, it doesn't complain about talking to dbus:

$ sudo -u quentin pulseaudio
W: [] caps.c: Normally all extra capabilities would be dropped now, but that's impossible because PulseAudio was built without capabilities support.
W: [] pid.c: Stale PID file, overwriting.
E: [] module-coreaudio-device.c: Skipping device with more channels than we support (64)
E: [] module-coreaudio-device.c: Skipping device with more channels than we support (64)

Finally, dbus in general seems to be working fine on my machine. dbus-monitor happily prints messages on the bus, and the DBUS_LAUNCHD_SESSION_BUS_SOCKET environment variable is set in my bash environment.

As of [fd9e82cb56afcc86a42b66f4b6ac9c273f8a562b/macports-ports], autospawn should be working and there's no need to launch pulseaudio manually. Let me know if you still have issues.
