I am trying the demo from github (https://github.com/andenore/NordicSnippets/blob/master/examples/i2s_master/main.c) with nrf52 demo board and when checking the signal on BCLK I see that it is doubled. Like
Any ideas why this is happening?

Hi,
This type of signal is normally due to bad grounding. Could you check your connection and see if it improves?
Kind regards,

Yes. It looks like it was really a GND issue. Not sure what I did, but managed to get the proper signal to the screen.
I'm still struggling with the i2s one sine demo from the examples, since I don't get a sine signal on the scope.
