Bug 509274

Steps to reproduce the behavior (at least on my machine):

1. Open https://www.deutschlandfunk.de/, the web site of "Deutschlandfunk", a nationwide transmitting public radio station in Germany.

2. Click the "Live" button once in the upper right corner on deutschlandfunk.de

At the bottom of deutschlandfunk.de an additional, horizontally positioned element gets displayed. With this element you among other things can stop and re-start the current live stream on deutschlandfunk.de.

By the way, at the right end of this horizontal element you will see the "Schließen" button, with that button you can close the additional, horizontally positioned element at the bottom of deutschlandfunk.de.

Expected behavior:

Normally, after only one click on the "Live" button on deutschlandfunk.de the live audio stream of "Deutschlandfunk" immediately is played, that is at least the case in Firefox 142.0.1. and in Konqueror 25.08.0 on my machine,

But Falkon does not play this audio stream.

Workaround to be able to listen to the live audio stream of "Deutschlandfunk" in Falkon:

3. With each a break of appr. 1 second click 3 times on the blue Stop/Play button in the the additional, horizontally positioned element at the bottom of deutschlandfunk.de. The blue Stop/Play button is shown close to the left edge of the additional, horizontally positioned element at the bottom of deutschlandfunk.de.

You can now listen to the live stream of "Deutschlandfunk" if this audio stream is not blocked for your location due to geoblocking.

The command "sudo journalctl -f" created the following three lines while I clicked 3 times on the blue Stop/Play button in Falkon:

Sep 08 13:16:25 <Host name> wireplumber[1237]: wp-event-dispatcher: <WpAsyncEventHook:0x55f73a50b8d0> failed: failed to activate item: Object activation aborted: proxy destroyed

During another, former Falkon session I noticed the following output by journalctl while I clicked 3 times on the blue Stop/Play button:

Sep 08 07:55:53 <Host name> wireplumber[1235]: wp-event-dispatcher: <WpAsyncEventHook:0x5654fa6ecb60> failed: <WpSiStandardLink:0x5654fa8e61a0> link failed: 1 of 1 PipeWire links failed to activate
Sep 08 07:56:25 <Host name> wireplumber[1235]: wp-event-dispatcher: <WpAsyncEventHook:0x5654fa704bc0> failed: failed to activate item: Object activation aborted: proxy destroyed

Please note that wireplumber and PipeWire are mentioned in these log output lines.

I am not sure if this is a wireplumber/PipeWire or a Falkon issue, but because this behavior does not occur in Firefox 142.0.1. and in Konqueror 25.08.0 on my machine I guess that the issue which I have reported here is a Falkon issue.
