lost sound when pieces are moved

I have lost sound when a piece is moved. I have checked sound settings and it seems okay both on chess program and PC. I cannot find a way to recover it. any ideas?

I also experience sound problems with Lichess, especially on my phone. What browser are you using?

Safari. It ran for a while no problem and then just stopped for some reason

Safari has some problems while running lichess.org, but you could change to another browser, so maybe the problem is gone. You could change to firefox, or google chrome. :)
Hope I can help with this information :)
