With this the connection from strawberrymusic-player and calfeffects are stable.

1.1.0-rc2 The currently running audio is not highlighted in color. It is only highlighted when I move the mouse over it. But in the next track, the color is gone again.
Xubuntu 22.04-4

Release version 1.1.0-rc3 its ok. No problem any more.

There is a new line in the playlist in the new version 1.2.6 of strawberrymusic.
<title>playlist 1023</title>
this is not changed when I save the the playliste with a new name.
so it would be better not to use this line withe title.

Hello Jonas, I would like to have the version 1.1.0 in the ppa:jonaski/strawberry
so i can update.

Release version 1.1.0-rc3 its ok. No problem any more.

I found a solution: there is a switch in playlist: automatically select current playing track. And it works!

Intelligent Playlists
At the moment a song will be stored at the end in last played. But I would like it if it is stored at the beginning of a song. Is this possible?

I have the same problem with Strawberry and Calfplugin. Strawberry is only present while playing a song. If I stop the song in Strawberry the connection disappers in carla. An if I start a new song, the connection is not Calfplugin.
System: xubuntu 22.04 pipwire jack Calfplugin

I have a problem with Strawberry to Calfplugin to System with Jack. If I play in one playlist and do not stop a song there is no problem. But if I stop a song or change the playlist, the connection get lost. And if I start the next Song in a other playlist Strawberry will not connect to Calfplugin but to System. Long ago I had the same problem with Clementine.
