CS19 Pack Structure Training module not playing sound

I’m not getting any sound when I’m trying to go through the new “Pack Structure” training module. Has anyone else experienced something similar?

I’m finding that it has no sound for the first few slides and just sits there for a while before the next bullet point, as though someone is supposed to be talking, but no sound comes out. It isn’t until the 3rd or 4th slide that we get any sound.

Any ideas?

Additionally, the CC option does not work @TimothyRogers
