Air UPnP (control Airport Express as UPnP devices)

[N2Audio]

Re: Air UPnP (control Airport Express as UPnP devices)

Hi all: I'm hoping someone in this community can help me. The controller/renderer randomly drops during playback. I'll copy the info level log below to show the exact problem I'm experiencing. Thanks for any help or suggestions.....

Setup:
PC using WindowXP w/latest updates
Asset by dbpoweramp as media server
air_upnp by dbpoweramp as contoller/renderer (physical device is Airport Express)
foobar200 v1.1.1 w/ foo_upnp component
Static IP addresses for both the PC and AE
All files are wav ripped from cd's

I'm using the optical out from the AE to a Benchmark DAC1. The combination streams perfectly, then suddenly stops as the controller drops from foobar/foo_upnp. The device will then re-appear and I can restart streaming once I add tracks back to the playlist.
Since it works at all, I'm assuming it's not a firewall issue?

Here's the log:

Re: Air UPnP (control Airport Express as UPnP devices)

It will not be updated to make compatible with AirPlay.

[iangrant]

Re: Air UPnP (control Airport Express as UPnP devices)

I have a couple of questions:

Will AirUPnP be updated for the new AirPlay protocol? (from AirTunes -- does it need to be? I don't know if anything changed beyond the name...)

Does anyone know of anything that does the reverse? -- i.e. exposes a UPnP device (renderer) as an AirPlay/AirTunes device so that iTunes can stream to it.

Re: Air UPnP (control Airport Express as UPnP devices)

It is unlikely to be developed further.

Re: Air UPnP (control Airport Express as UPnP devices)

Hello?? Spoon? Is this still being developed? Is anybody even monitoring this thread???

This:

HOWEVER, something weird happened: as soon as I re-started the AirUPNP service, music started playing on my receiver through the airport, resuming from where I stopped it last night. I actually had to look for my iPod touch, wake it up and start plugplayer just so I could stop playback.

happened to me again this evening. The AirUPNP-Bonjour combo, as usual, screwed up my DNS. Manually stopping and starting the DNS Client service fixed the issue but again triggered streaming to my receiver. Exactly as stated before.

I would be nice if somebody acknowledged these posts, even if the developers dont have any answers or solutions.

Re: Air UPnP (control Airport Express as UPnP devices)

Yes, it is an apple service. But until I installed AirUPNP, Bonjour it never caused a single problem. Something is happening in the interaction between the two services that eventually screws my DNS cache (apparently).

As I stated before, the problem crops up very intermittently so it's only a minor inconvenience, but it also makes it hard to diagnose. Since AirUPNP is still in beta, I'm sure the developers appreciate feedback.

Re: Air UPnP (control Airport Express as UPnP devices)

"Bonjour Service" is a Apple application.

Re: Air UPnP (control Airport Express as UPnP devices)

Okay, it's been 5 days and it just happened again. Apps stopped resolving DNS addresses after 5 days of the above error showing up on event viewer.

As before, ipconfig /flushdns, does nothing. However, instead of rebooting this time, I disabled the AirUPNP and DNS Client services and then re-started them. After this, I have full connectivity back.

HOWEVER, something weird happened: as soon as I re-started the AirUPNP service, music started playing on my receiver through the airport, resuming from where I stopped it last night. I actually had to look for my iPod touch, wake it up and start plugplayer just so I could stop playback.

Very strange. I'd love to hear any ideas you might have on this.

Re: Air UPnP (control Airport Express as UPnP devices)

Anyone else come across these messages in the Event Viewer logs? (see below: 'DNSServiceResolve active for over two minutes. This places considerable burden on the network')

I'm getting the exact same error:

Log Name:      Application

  <EventData>
    <Data>Client application bug: DNSServiceResolve(Pioneer._airport._tcp.local.) active for over two minutes. This places considerable burden on the network.</Data>
  </EventData>
</Event>

The error will come up every few minutes (often starting when I start plugplayer on my ipod) but it doesn't seem to effect network performance and my PC can run for several days or even a week or two without any apparent problems. That is until, one day, I'll get an error message that bonjour service has stopped and my internet connection will be hosed.

I'll still be connected and I can ping various addresses, but my browser can't seem to resolve dns addresses. I've tried ipconfig /flushdns, /renew, etc. to no avail. This has happened to me 2 or 3 times and, so far, my only solution has been to reboot. I haven't really done any real testing but the symptoms certainly look like there's a problem with the DNS service caused by AirUPNP, Bonjour, or both.

Re: Air UPnP (control Airport Express as UPnP devices)

It will not work as you are describing (something would have to capture the audio).

Re: Air UPnP (control Airport Express as UPnP devices)

Hello

Just a few question to be sure :

I've installed air upnp so it appears in my network window as upnp device.

I want to be able to stream to the airport express any audio from my computer such as sound from website in Firefox (music me, deezer, last fm....) windows media player... and any other app.

Is it possible ? do i need more things to install ?

I've tried to play from win media player with the "play to" fonctionnality. It sees the AE but no sound output from it and it skip to next track after a few second.

Do i miss something ?

Thanks
Nicolas

Re: Air UPnP (control Airport Express as UPnP devices)

You would have to try, I have not tested.

Re: Air UPnP (control Airport Express as UPnP devices)

Hey,

as the AppleTV also can run as an airtunes speaker can it be controlled just like an airport express?

Re: Air UPnP (control Airport Express as UPnP devices)

is this a planned feature or not?

Sorry not possible.
