iOS-based UPnP renderers not being discovered

[hdfssk]

I’m having problems getting pulseaudio-dlna working with any iOS-based renderer (on fedora 25), and could use some troubleshooting advice.

• If I understand correctly, it should be possible to start (for example) BubbleUPnP on an Android phone, then start pulseaudio-dlna, and “BubbleUPnP” would then appear under ‘Output’ in sound preferences, or under ‘Playback’ in pavucontrol; choosing BubbleUPnP would then send the pulseaudio output to that phone.
• On my test setup (a fedora 25 system and iOS 10.3.2 iPhone), pulseaudio-dlna is not creating any upnp devices, whether started as root or as an ordinary user. Because the Tested Devices list doesn’t seem to contain any iOS apps, I’m not sure whether there’s something wrong with my fedora setup, or whether the iOS apps I’ve tested with aren’t advertising themselves as renderers properly.
• My fedora machine’s firewall was turned off for these tests. The pulseaudio output from a run as root is available here.
• Is there any specific iOS UPnP renderer app that it would be useful for me to test with? I’ve made no progress testing with random ones, so a concrete recommendation would be a good sanity check: “This app should definitely work, if it doesn’t it’s likely the network or fedora config.”
• Are there test commands I can run on the fedora machine to check whether 1) pulseaudio-dlna is performing discovery correctly & 2) the problem’s with my fedora config or with the network itself?

Glad to provide any additional info, try different pulseaudio-dlna builds (I’ve attempted 0.5.2 and master as of May 26 2017), or whatever else is needed.

Hello, could you please run pulseaudio-dlna without root and create a full debug.log using the master branch?

pulseaudio-dlna --debug 2>&1 | tee -a debug.log

When devices are not being detected most times it is a firewall issue or a network configuration. What's your network setup like? Router, wifi, cable, wifi extenders? And what's their IP addresses?

Is there also BubbleUPnP for iPhone? On Android I would say that's the application to go for. If not, search for a DLNA / UPNP app which provides Server capabilities.

I've found that most iOS apps doesn't include an UPNP renderer at all or as needed by pulseaudio-dlna so is hard to find one that works, not even VLC.

So far I've only found two that show an entry in the devices list on the audio preferences pane, Manning Lu's Himu (not support for iOS 11+) and e2esoft's TV Assist (have to enable renderer in the app's settings). Both are free as I wouldn't waste my money on testing anything that most probably wont work anyway.
