Wally, I just tried several of those calls, and all of them played for me without problems. And at the moment I’m running on an ancient backup XP machine until I get my Win 7 machines rebuilt. Not that I know what might be happening on your machine, but sometimes PCs get balky. Sometimes the speaker gets turned off without being noticed or remembered. Sometimes the PC’s sound card volume gets reset to zero. Just as a check, are you able to hear any sound from any YouTube video? That’s my usual check to see if there’s something gone haywire on my PC or its settings.
