Hello.
I observe this behavior since 17th release and I keep upgrading hoping that you finally fix it. Now it's 20th with the same bug.
And the most intriguing thing is that foobar2000 does this right.
So, I have PerfectWave DAC player, I have "Audiophile 24-bit DAC" DLNA server configured in MC.
It plays well, sound quality is great. I have a bunch of flac rips with cue track info files.
Some rips have one solid flac file with cue, others consist of multiple flac files.
Problems:
1. Split flacs play with huge pause between. No skipless playing.
2. Solid flac plays skipless but only when MC plays it as a whole album. Sometimes it plays first track over and over and I can't say why MC decides to do so. It's random. Some solid flacs play right, some don't.
Again, foobar2000 does everything correctly. It means DLNA standard allows to do it right. MC doesn't.
P.S. While playing whole album Position slider shows playing position only for the first track. Then it stays at 100% for all subsequent tracks. "Current file" window above it shows "1 of N" (where N is the number of tracks) all the time. I.e. when it plays second track it shows "1 of N".
P.P.S. Playing via USB is perfect on the same player, no single issue described above.
