Audiocast M5 not detecting on Aruba devices - works on non Aruba gear

HI there

 

I need some help please – bought some AudioCastM5 devices. 

A really awesome device but have an issue that i cannot figure out.

Done all testing to say the issue is not with the Audiocast Devices (well does not seems to be).

 

The Audiocast M5 devices , both have the latest firmware 3.8.6030.0 (and I believe this is the latest).

 

If I connect it to My Aruba IAP-207 devices (Virtual Controller) running any version of firmware version 8.3 (even 8.4 - did not try earlier versions) , the iOS and Android APPS cannot detect the AudioCast devices but DLNA and Spotify Connect works fine.

 

Also tried on IAP-315 connected to Aruba Central , same.

 

I do know it is not a firewall,vlan and or switch issue , when I use Ruckus/Huawei on the same network , the apps can detect the devices.

Just for interest sake the switch is a HP/Aruba 2530 and firewall is a WatchGuard

 

I would like to use the APP for the advanced functions like getting the audio in sync (across the house) and or different music sources on different areas and there is just no way I am getting this on the Aruba wifi.

 

If I sync the music sources on a Ruckus/Huawei and then chnage the Auduicast devices o the Aruba Wifi , that snc (all audio is the same ) it still works  -- so technically multiroom audio works , but again I cannot configure anything via the app. So if i want to switch back to individual zones , i need to change them back to Rucks , use the app to use them as individual zones again.

 

So issue is clearly Aruba and or firmware with Audiocast.

If the APP was able to allow me to manually enter the IP addresses of the Audiocast devices , I am sure that will be a great workaround but the APP cannot do this.

 

 

I have enabled the Google services , Spotify services …even allow all , analysed the services with WireShark and just cannot figure out the issue.

 

I have also disabled multicast filtering ,tried dynamic multicast optimisation , tried changing the 2.4GHZ to legacy mode. There are no access rules configured . Switched off 802.11 r , k & V.

Spent hours and hours on this , just cannot figure this out.

 

Did also check out posts about ChromeCast Audio - not the same issue , just the app.

 

Pretty sure it is a multicast issue?

 

 

Would appreciate your help.

Have you tried the following at the same time:

  • Disable AirGroup
  • Disable Multicast Filtering.

Even if you have "Multicast Filtering" disabled, AirGroup I believe will still filter mDNS/SSDP(DLNA) discovery traffic.

 

I suspect the problem is similar to issues with the Roku App (ecp) - due to Roku utilizing invalid syntax for their "URN:" per RFC 2141  - which I've made several attempts to Roku to acknowledge - at which point I think they just don't want to admit they're using invalid syntax (my initial inquires were phrased more if they agreed with the Aruba AirGroup Developers assessment that Roku's syntax was invalid) - https://community.arubanetworks.com/t5/Wireless-Access/Roku-streaming-stick-Not-registering-with-AirGroup/m-p/378957#M77916

I suggest that as I did a packet-capture on my phone with the the AirCast App - and saw several SSDP packets with ST of services missing the "urn:" prefix - one of them being "ssdp:wiimudevice" which was mentioned in another post a couple years ago (different device though) - https://community.arubanetworks.com/t5/Controllerless-Networks/UPNP-services-on-IAP205/td-p/312105

 

Airtame had a similar issue with their syntax based on packet-captures/other discussions, but since they have enterprise/paid support - they corrected their syntax and have a special configuration document - https://help.airtame.com/tips-and-tricks/tricks/how-to-enable-discovery-with-aruba-airgroup

Hi there .

Thank you very much for your reply and sorry for my delayed response .

 

I disabled airgroup via CLI , commit apply and VOILA it worked.

 

Confused , i must admit, i need to read up a bit more. I thought the allow all service and other services would have sorted it out.

 

Did try to disable mutlicast filtering initally too (made no difference , sorry for not mentioning it). 

 

So "no airgroup"  did the trick.

You're welcome Tedster. I believe the "allowall" airgroup service probably would have worked if the Audiocast M5 was using a uPnP 1.0 Architecture Compliant Service URN/ID. I'm basing that theory on my issues with the Roku where "allowall" was enabled, I could see the Controller started issuing queries for a new service under "allowall" called "urn:Roku:ecp" -> which unfortunately will never be found as the service Roku is advertising is "Roku:ecp". I'm assuming it's appending the "urn:" because that's the standard. :-) It's more complicated than that from what the AirGroup Developers informed me - https://community.arubanetworks.com/t5/Wireless-Access/Roku-streaming-stick-Not-registering-with-AirGroup/m-p/378957#M77916

 

You could do a "show airgroup blocked queries" to see what queries AirGroup was blocking due to an AirGroup Service not being found in the table. I always found "roku:ecp" in mine and noticed everything else had "urn:" - along with packet-captures - which led me to working with Aruba TAC.

 

Still, it's very intersting to analyze packet-captures of SSDP/mDNS. :-)
