HLS Stream Tester with Stereo/DD tracks failing to start

I have encoded a title and provided the necessary parameters per the HLS spec on how the audio EXT-X-MEDIA should be named.  When launched, the stream tester starts up but eventually throws a generic 'Video PlayBack Error": An unexpected problem (but not server timeout of HTTP error) has been detected.  Trying to understand how to debug this or capture some more detailed response from the stream tester app.  I presume it's something to do with the DD track, but no idea as to what would be the issue.

Thanks.

Test Device: Roku 3090RW - Roku Express

Software: 10.5.0 4208-AE

HDMI connection to an monitor with internal stereo speakers.
