Additional notes

This happens on a fresh installation.

[Abraka]

Try to delete all players existing in settings-->players. Then create new one a try to play some music.

@Abraka Many thanks, that actually helped.

Additionally I want to mention that I have seen above exceptions never since filing this bug. No matter if the players are working or not.

Same issue (but no related error message) and same solution here. This was however a fresh install, hence no database or configs were present, only the airsonic.war, it is hence unexpected that the default web player fails to play music and a delete/recreate cycle required.

In browser console I see:

>>> SEND
destination:/app/playqueues/0/play/mediafile
content-length:8

{"id":1}

but nothing happens.

System is Debian Bullseye with OpenJDK 17.

I can reliably replicate it by removing all Airsonic data aside of the airsonic.war to have everything freshly created. Change/add media library, scan, refresh, play (now, last or next does all not work). Then delete player 0, page reload (which creates an identical new player 0) and voila, music files play 🙂.

I it needs to be looked at the initial config/database creation when nothing exists yet. I can help testing/debugging and provide any information from the system you may need.

Hey guys, not sure about your priorities and whether this issue affects all fresh installs, but for us it is the major reason why we cannot ship Airsonic-Advanced as replacement for Airsonic to our users. Users will install it, recognise that trying to play anything or adding anything to the query doesn't work and uninstall it. It's all about the first impression if this shall succeed in a broader way, and the one major feature (play music) broken OOTB is a deal breaker.

Simply cloning the existing default web player and deleting the existing one already does the job, so I guess the default one is somehow defined in a legacy/incompatible way but is not migrated or so?

[MichaIng]

I think I may have found the reason. I recognised that it is not an issue with v10.6.0, so I compared the default web player. On v11 snapshots it is Player 0 [admin] while on v10.6.0 it is Player 1 [admin]. Deleting the player in v11 snaphot, having the default automatically recreated, leads to a Player 1 [admin] entry as well. Is the index 0 probably invalid and playback only works with an index of 1 or higher?

EDIT: Cloning Player 0 to get Player 1 works as well. So it seems to be really the index.

[randomnicode]

👀

If Player 0 is always removed at migration or never created, might solve the issue?

[MichaIng]

Never created on a fresh install and removed on upgrade would make sense. Not sure whether it ever worked so that it makes sense to migrate it somehow?

[MichaIng]

Great, I can verify the latest snapshot solved it, many thanks 👍!
