No issues reported by toaster. (not in actual yellow toaster, not in the log)
"Auditioning style: C:\bb\RealTracks\Data\Style Demos Audio\_OUTEAST.wma [2026.1237.0, 4/25/2026 8:42:29 AM]"

However I had pinpointed the issue!
Advanced setting in Windows for playback is set to 48K (so as my interface) BIAB forces my interface to 44.1 > WMA doesn't play. Going into Windows settings and changing playback to 44.1khz = WMA demos in BIAB plays.

P.S. Exiting BIAB (under Win set at 48K) - Plays WMA fine.

Solution? Definitely not.
