[Bug 896688] Re: avahi provides incorrect IP address to pulseaudio

[Mike Wild]

I've just encountered this issue with Ubuntu 16.04 / avahi-daemon
0.6.32~rc+dfsg-1ubuntu2. I have an AirPort Time Capsule, however the
problem is the same - pinging Airport-Time-Capsule.local resolves to an
incorrect 169.254.x.x IP address. Now interestingly, none of my other
devices (Apple or Android) have issues resolving this hostname. More
interestingly, I can successfully resolve hostnames of other Apple
devices from Ubuntu, just not the Time Capsule. This suggests there is a
specific compatibility issues between avahi and the Apple AirPort's mDNS
implementations.

I have a pcap of mDNS traffic after the Time Capsule was power-cycled.
Is there anything else I can provide to help?

Title:
  avahi provides incorrect IP address to pulseaudio

Status in avahi package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 10.04
  Packages avahi-daemon 0.6.25-1ubuntu6.2

  I'm using an airport express with pulse audio and I believe avahi-
  daemon is providing/resolving the wrong IP address to pulse audio.

  Using the following command,  avahi-browse -r _raop._tcp

  I get:

  + eth1 IPv4 00254B09A042 at Base Station 09a043              AirTunes Remote Audio local
  = eth1 IPv4 00254B09A042 at Base Station 09a043              AirTunes Remote Audio local
     hostname = [Base-Station-09a043.local]
     address = [169.254.135.173]
     port = [5000]
     txt = ["sf=0x5" "fv=74200.9" "am=AirPort4,107" "vs=101.9" "tp=TCP,UDP" "vn=65537" "pw=false" "ss=16" "sr=44100" "da=true" "sv=false" "et=0,1" "ek=1" "cn=0,1" "ch=2" "txtvers=1"]

  where the address (169.254.135.173) is incorrect. It should be a
  192.168.1.X address which is already assigned to the APEX from the
  router using DHCP. I've had to specify the correct IP address to
  pulseaudio when I manually load the module_raop_sink module in order
  for it to properly stream music to it.
