No sound on next track

[TETYYS]

Sometimes next track (after current one ends) will have no sound, although I can't seek in tracks (yet?), I can see that the seconds are running, but whole bar is empty instead of blue. The track title doesn't change at the end, so I don't really know if it can't play the next one or can't switch tracks entirely

Not track specific, failing to reproduce it on same two tracks. Happens randomly..

This sounds like a problem with the transcoding, but unless you find out how to reproduce it there's little we can do.

Can you please provide the output from the javascript console and the server log when this happens the next time?

[TETYYS]

Sure, but that can take a little time
