Some FLAC files with embedded cover playback failure
VLC can't play some FLAC files which seem to have an embedded cover in the comment field. The cursor is running, the time counter is counting like a normal playback but no sound is heard. However, FFplay is playing these files and is displaying the embedded cover at the same time.

Audacity can open them and here are some other well known players which are able to play these files: foobar2000 and Winamp (both are also displaying the cover), WMP using madFLAC filter or LAV Filters or Media Foundation FLAC Codec, MPC-HC using its internal filters, Audacious, AIMP, Zoom player.
