First, how do I know what build I am using? I tried to find out before posting, but there is no typical "about" or a location in "help" which would normally show what build is executing for most other programs as far as I can easily find. As far as playback is concerned, it is set to USB (an HP 7000 headphone device). But the device is irrelevant.
I want to emphasize, the problem is not in the playback device. If so, it would not work in the first place. The problem is that somehow, the playback works one time, and afterwords does not work at all. Regardless of the playback device and whether or not Spin It Again was communicating with it, the cursor should progress through the song and the time counter should increase as Spin It Again was playing through the song. This is the problem, regardless of the playback device.
