Happy 2026 #Podcast - #UPnP / #DLNA folks.

Wie bringe ich die Podcastsammlung der Hausbewohner (eine handvoll #OPML-Files) per DLNA/UPnP auf die diversen Streaming-Devices?

Einschlägige Suchen liefern erschreckend wenig Ergebnisse.

I'm having trouble accessing the UPnP/DLNA media service from my NAS on my Linux PC. Anyone any idea what might be wrong?

➡️ VLC on iPhone can see the UPnP service just fine
➡️ Dolphin, VLC and Kodi on the PC can see the SMB shares of my NAS
➡️ VLC and Kodi on the PC can *not* see the UPnP service

Things I tried that did not make a difference:

➡️ Install VLC from Flathub instead of my distro's RPM package
➡️ Disable IPv6 in the PC's network settings
➡️ Add upnp-client to the allowlist of the PC's firewall
➡️ (Update) Connect PC directly to router instead of through eth switch

Anyone know why #UPnP appears to be broken on #NixOS?

So far I only found one forum post attributing it to a "beyond repair" broken Multicast in #NixOS
