 Hello,

 I have Pulseaudio working on box X, MPD working on box Y on mpd server 0.
 It works perfectly. Anytime I hit 'play' it just works. I tried putting
 the same exact configuration on my wifes' computer (She is on box Z, MPD
 playing on box Y, mpd server 1). Sometimes, it refuses to play. Try again
 3 minutes later (nothing changed) it will play. There's not much telling
 from the logs, but what it does tell me I will paste to the best of my
 ability here:

 }}}

 Here is some observed sample output (From box Z):

 }}}



 Most of the time when the error occurs, after I press play in MPD (on box
 Y server 1) I get:

 {{{
 Nov 07 17:42 : problems opening audio device while playing "New
 Music/GERZ.ru_Enigma__2003__Sleep/Enigma - (2003) - Sleep/02 - Center Of
 The Sun (vocals by Poe).mp3"
 }}}


 Rarely, but sometimes I get:

 {{{
 Nov 07 17:42 : Cannot connect to server in PulseAudio output "Trish's
 Computer" (attempt 1): No such entity
 }}}



 Sometimes, If I don't have a few minutes to wait, I restart the services
 (pulseaudio on Box Z or sometimes mpd server 1 on box Y will make it
 work).

 I have no idea why this is happening; and I'm not really sure where to
 start to try to find out more.

 Also, about the
 {{{
 Nov  6 19:39:05 tulip pulseaudio[5618]: socket-server.c: socket(PF_INET6):
 Address family not supported by protocol
 }}}

 I'm not sure why I'm getting this error, I have IPv6 support compiled in
 on box Y, but not box Z, which is strictly IPv4. Nor do I have IPv6
 support compiled on Box X and it works fine. I have diffed all configure
 files (pulse/ and mpd/) of boxes X and Z and they seem fine. I also do not
 get this IPv6 warning/error on box X.

 If there's any information I can help with or any way I can turn on extra
 debugging please let me know. I really need to get this working for the
 wife :)
