UPNP Delay

[Gödel]

Pardon my ignorance again, but I'm having a vexing issue on my main PC, a relatively fast (for me) Ryzen 3700x with a decent M.2 SSD on a gbps ether-network.

When I open VLC to try to play music from my UPNP record collection, it takes quite a while to find it. I just checked again, and it took over 6 minutes.

Other PCs in my mini-data-center connect to it in seconds, and so does my phone.

How can I get this major lag down to a reasonably short delay?

TIA​

Windows? Linux? What are you using to host your music? Dedicated server application or just Windows Media player?

It's running Ubuntu Linux, and the music is hosted on Windows.

What happens if you turn off the Firewall on your Linux PC before you search?

Confession: I'm using Rhythmbox instead of VLC, because in my search for the nasty problem that VLC skips the first 2 seconds of every song, I haven't found a solution. So for now, I'm just leaving Rhythmbox up. I'll check into turning off the firewall sometime.

I'm a sporadic multimediot. I occasionally like to listen to music while I'm cruisin' the web, or when I'm watching sports (I don't need the announcers to tell me what's going on on the field.)

I was going to suggest running your music through Squeezebox or Jellyfin. UPNP / DLNA i certainly works, but you may have an easier time in something that handles presentation as well.

Upon further review, I figured out that my other PCs connected quickly because they weren't running firewalls. I don't know why; all 3 are running regular Ubuntu installs to which I didn't do anything UFW related.

I googled a bit, and I found to open ports 1900 and 5000, and then VLC would see the record collection fast, but then error out when I tried to listen.

OTOH, I found that if I open port 3689, Rhythmbox found the records pretty quick, and opened (at least one of) them fine.

I'm listening to Miles Davis right now:

Thank you so much, Mr. Mercutio!​

I'll check into Squeezebox or Jellyfin sometime.

Huh. I either use Jellyfin or just access everything via SMB or NFS. So there WAS once upon a time a reason to have UPnP enabled that wasn't just opening holes in your firewall for funsies.
