When I open ums web interface (no matter if I do that on the machine ums runs on or if I open it from another machine) I can browse through my media but when I try to play it nothing happens. Also all titles have media lenth shown as "0:00".
What can I do to find the problem?

[edit]
If I understand the log well then there is no compatible player found connected with UMS.
I try to play mp3 files:

This is the log:

What can I do?

We will need the full log to be of any help. See the section in red above.

Having said that I couldn't get any audio (mp3 + flac) to play on my system using the web interface in any V11. I'll post an issue on Github for the devs to see.

Does this happen for videos too or just for audio?

Ok, I full log is attached now. I actually feel quiet unconfortable to post such log to the public because it may contain sensitive data of my network but if there is no other way...

The 2 files are a spanned zip archive as the data exceeded 5MB limit. You need to rename the 5MB part to "ums_dbg_2022-06-16-09-20.zip.001" and the small part to "ums_dbg_2022-06-16-09-20.zip.002" and place it in the same local folder to open it. 7-zip or other apps will recognise this format.

During the session when the log is catured I tried to play "Katy Perry - Firework.mp3". The cover art is displayed in the browser and there is also a control for play and a progress slider, volume slider etc... but nothing happens when I click on the controls...

Video playback via web interface seems to be possible. I haven't logged it because it is not part of my post.

For playing mp3 which does not work via web interface:

During the session when the log is catured I tried to play "Katy Perry - Firework.mp3". The cover art is displayed in the browser and there is also a control for play and a progress slider, volume slider etc... but nothing happens when I click on the controls...

I guess the relevant section in the log is this:

Thanks for posting the logs. The logs do not have any sensitive data about your network, just the communications between UMS and any renderers, your media and the decisions UMS makes to play them. There is nothing shown that is visible outside your local network.

The relevant parts will be the communication between the browser and UMS as in those snippets you posted it shows that those files will be streamed.
The other parts saying something is incompatible is it testing each transcoding engine to find the right one if it is needed. It then matches the format to mp3 so it determines it will be streamed.

Code: Select all

Matched support line f:mp3 n:2 m:audio/mpeg
...
Final verdict: "Katy Perry - Firework.mp3" will be streamed

When I was testing on mine it looked exactly the same as you describe but works normally for 10.21.0 so this is definitely a bug with V11.
There had been some significant changes with the networking and this one may have slipped in, I'm not familiar with the new logging information but will be helpful for the devs when they look at it.

This is the Issue on GitHub if you want to follow it for updates.
