[PaulL]

I'm continuing to have issues getting this working well. Other people clearly have it working, so I suspect there's something in my specific setup. My reading of the logs suggests it's most likely a timeout issue - perhaps my 3G internet connection has more latency than is assumed in the settings.

BACKGROUND
My setup is a linux quad core mobile chipset, running kodi, and I upgraded to latest spotify plugin this morning. I have pulseaudio running (installed so the native Spotify client would work, but I had the same behaviour with native alsa audio).

The native spotify client does play, with spotify connect as well. So whilst my setup is probably the cause of the problem, whatever it is is an interaction with Kodi and the Spotify addon, not just a problem with Spotify entirely.

ISSUE
My spotify connect won't play at all in kodi, although the logs suggest the commands are coming through. Running librespot directly I can see the files downloading, although I get no audio (presumably due to configuration of librespot and audio).

Playing songs from the playlist within the plugin fails the first time on a song, but when playing a song already cached plays fine. Kodi log shows a timeout error. Once the first song plays in the playlist the next song doesn't play, even if that song has been previously played and is therefore cached.

LOGS AND DETAIL
When calling directly from librespot, it seems to stream fine, although I'm getting no audio, no doubt due to the alsa settings. As can be seen librespot is busily downloading the track, and presumably trying to play it to the alsa sink:

When calling from within Kodi for spotify connect, it just doesn't play anything, although it clearly is trying to:

Second time calling from spotify connect, file already downloaded/cached, still no playing. I'd hoped perhaps once the file was downloaded it might play, same as it does when playing from the UI, but no joy, so potentially a different issue than when playing from playlist:

First time when picking a track directly from playlist in the UI, doesn't work:

Second time calling from playlist, file already cached. Works and plays audio:

However, it doesn't go to the next track in the playlist, and nothing that looks relevant in the log. When I selected that track directly, I got the following error:

This one crashed Kodi entirely, and may be a different issue.

Finally, I also noticed the Kodi UI hangs sometimes when trying to start a track - so something is perhaps blocking the UI. I'm not sure if that is maybe contributing.

Any thoughts or diagnostic paths I should follow would be gratefully received.
