RV PyMu compareFromVersionIDs does not play audio


I’m running the following script to compare MOV versions in RV from a list of version IDs:

rvpush.exe py-exec "import pymu; pymu.MuSymbol('shotgun_mode.compareFromVersionIDs')([37314, 36379, 36291])"

It works great, with the exception that RV doesn’t play each MOV’s audio, even when switching the RV stack to the default sequence. The source MOVs themselves have audio and work fine if played in RV individually.

Is there a way to enable audio when comparing versions? Not sure what I’m missing so any ideas would be appreciated, thanks!
