Thanks, that was it. My experiments indicate that the JBR V1 won't
play files sampled at less than 32k through the digital output.
Here's how I resampled to fix:
1. Install free Audacity and the LAME mp3 encoding library.
2. In preferences/File Formats/MP3 Export Setup, make sure Bit Rate is
set to 48 or higher (any lower won't support sample rates of 32k).
3. File/Import the mp3 that needs to be resampled.
4. In the "Project Rate" box at the lower left of the big project
window, click and type in 32000.
5. File/Export the mp3.
If anyone knows an easier way to resample for free, that would be
nice... I've got a lot of files to convert.
