[BUG] Librespot fails when using DJ X Mode while switching from locally playing to using librespot

[cfacer]

Describe the bug:
While having the DJ X playlist selected and playing locally in spotify, user is unable select librespot speaker to play from. Resulting logs in docker container show the following error:

librespot_connect::spirc] Invalid state { the provided context has no tracks }

Adding this bug to gioF71/librespot-docker as this is the image being used yet I was unable to find anything in the librespot-org/librespot issues list pertaining to this.

To Reproduce:

1. Open Spotify on a client device
2. Select the DJ X playlist and start playing locally
3. From the "Connect to a device" icon (speaker), select your librespot device
4. Review logs

Expected behavior:
Formerly librespot used to just discard the DJ X notifications and pickup with the next song being played.

Docker run command:
docker compose up -d

Docker-compose.yaml file:

#version: "3"
services:
    librespot:

Operating system(please complete the following information):

Additional context
Attached logs are from a fresh start of the docker container, attempting to push audio to librespot while DJ X playlist is playing a song, then waiting and eventually selecting a song to play directly (Highway to Hell) which works without issue. Timing gap is due to performing testing while documenting bug.

Hello, and thank you for the detailed issue you are reporting.

The current image includes a development version of librespot, which fixed some connectivity issues.
There is a new version v0.7.0 since a few days, but building a new image with this new version will require some work and testing which I will be probably able to perform next week.

But, unless this specific issue is fixed upstream with version v0.7.0, I find hard to think that the problem is with the docker image.
Would it be possible to test some other build, like e.g. raspotify, and see if the problem happens with that as well?
Unfortunately I do not see any binaries around with version v0.7.0 of librespot (at least from a quick search on Moode forum and raspotify itself) so there is not easy way to try the newest version unless you build it yourself.
Any test on your side will be useful.

Also, apologies but I am not that expert of spotify. I tried the mobile app briefly but I don't understand if the things you mention are some new features or what... I am probably missing to understand how to reproduce the issue.

As an alternative, would you like to try SpotConnect? It can create a Spotify Connect device on top of a UPnP or an AirPlay 1 device. It's a different implementation, worth testing. I also have a docker image for this here.
You will need to also run shairport-sync, mpd+upmpdcli or gmrenderer-resurrect if you want to use your desktop computer as the player as it seems that's the thing you are doing.
Cheers.

Hello, see this workflow run. The resulting image here include version v0.7.0. The image works for me, although I did not test your specific use case.
I selected a few playlist and they appear to play properly.
