See devices, connects, and plays. But no sound.

[stanleylai]

Been wrestling with this for awhile. I see my Google Chromecast devices on my iPhone, and can play to it. But no sound is produced. These are the errors I see in the logs. What are the reasons they are not connecting?

I have my iPhone, AirConnect, and Chromecast devices in separate VLANs, but with mDNS turned on and open firewalls access across them. Any tips?

Thank you!

I'm having a very similar problem. My logs are full of

Same thing here.

I was having a similar issue, and I found an answer in this https://community.ui.com/questions/Airplay-across-VLAN-How-to-do/0362cb7f-f38c-43ba-b10e-c2e5cc9dbe16 forum post. I had to manually add a rule from my IoT VLAN to my Home VLAN with return traffic on UDP ports 40000-54000.

So, if anyone is using a Unify router, the firewall setup is as follows:

From IoT network, port ANY to Home network (where my phone was), port 40000-54000, Allow (check the Auto allow return traffic checkbox), and protocol is UDP.
