I have v2016.10 of Sam Broadcaster Pro running under Windows 10 64bit.
I noticed that my .flac files show "-0:00" as the duration but they play except for a few. There are a few that will load in the deck, or in Song Info (right click the track) but will not play. Instead, the track is added to history and the deck ejects it. In Song Info -> Settings, when pressing PLAY, flashes the track info then blanks out and doesn't play.
Why are some .flac files playing and others are being rejected? Is there something I can look for outside of SAM to determine the trouble tracks?
