When I try and "Read Aloud" it appears to be working (animation moves, start/stop work, voice selection available etc.) but I get no sound. I have checked all the sound settings and everything else works, including video via the browser, just not Read Aloud audio.
@HotCakeX Unfortunately this is a work machine so I am at the mercy of their rollout. However, on my home machine, which is up to date, Read Aloud works just fine. Perhaps I will wait for the work machine to get a little more caught up and try again later.
