Can't jump to specific track in playlist

[michaelherger]

Describe the bug
I loaded up a playlist. Then I wanted to jump to the last track in the list to see how it would handle an "end of queue" event. I could click any track in the list, but it would only stop playback, not jump to that track.

To reproduce
Steps to reproduce the behavior:

1. librespot -c . -name tescht --verbose &> test.log (yes, I know, got the name parameter wrong, but anyway...)
2. Connect with Spotify for macOS (Apple Silicon) 1.2.45.454.gc16ec9f6
3. Play https://open.spotify.com/playlist/37i9dQZF1DZ06evO2UhT7X
4. Try to play a random track in the queue

Log
Too long to embed here, I guess. I'm not sure what the relevant part of it is: test.log

Host (what you are running librespot on):

• OS: macOS 14.6.1
• Platform: Mac14,9 (MacBook Pro M2 Pro, 14")
• librespot 0.5.0-dev e02e4ae (Built on 2024-09-26, Build ID: 0kQU3dVK, Profile: debug)

Additional context
The same interaction would work if playing from the application directly (not sending to librespot)

I can't see anything going wrong in the log, it seems to be doing what it's been told to. I also can't reproduce this, but I don't have the macOS client. Does it behave any better with a different audio backend i.e. passthrough?

[michaelherger]

I first encountered it with the pipe backend, yes. But as that was using my fork. I now tried again with passthrough and pipe on the dev branch and am seeing the same.

The problem really is that librespot seems to totally ignore the fact that I clicked a button. There's nothing logged, nor would playback jump. In pipe mode, though, playback paused. I'm not sure whether there's a timing related issue, as piping would simply download the full track and jump to the next within seconds anyway. But I see nothing logged in default logging mode. In my log file OTOH you'd see the following when playback of a track starts:

[2024-09-26T05:53:07Z DEBUG librespot_playback::player] command=Play

Then when I click a track:

[2024-09-26T05:53:11Z TRACE librespot_connect::spirc] Received update frame: Frame {
...
}
[2024-09-26T05:53:11Z TRACE librespot_connect::spirc] Sending status to server: [kPlayStatusPause]
[2024-09-26T05:53:11Z DEBUG librespot_playback::player] command=Pause

So I must assume there's something in that big Frame dump (900 lines?) which tells librespot to stop?

[michaelherger]

I should probably have dumped that frame here:
