I don't hear any audio on the new Bittle board configuration video from Jan 3 on this page https://bittle.petoi.com/4-configuration. I clicked over to the youtube version too but don't hear audio there. I do hear audio on the other Bittle videos such as assembling the frame here: https://bittle.petoi.com/3-assemble-the-frame, but not on the board configuration video.
There's no sound in most part of the board configuration video. There is sound after 5:30 to show the board's reaction. https://youtu.be/MbTN4IcuqLo?t=345
Yes, if I jump to 5:30 I do hear beeps and audio. I assumed there was a spoken narrative walking through the steps from the beginning.
