Same problem on Mac except when i'm checkmate...No sound when I play !!!
Sound Issue

Try using the new site - sounds are much better there. Visit www.chess.com/switch

Chome, Windows 10, just rebooted, no other apps, and no sound when opponent moves. Except piece captures do make sound. First time I had the problem after a reboot. Lost my game.
erik: We're now on the new site (which I was sent to today) - and today the sound issue is still here...

I've realized the problem occurs whenever I leave the tab and come back. I do that often while in the middle of a seek (i.e. switching music or googling something). When I come back about half the time the sound has completely turned off. It seems to happen if ever I click on another tab during a game, as well.

The site you have mentioned "can't reach" therefor I tried this one https://techloris.com/windows-10-no-sound/ when I had no sound while playing chess on windows.

I recently switched to firefox, and have the same problem, where sounds only play some times. It makes me not want to play. Does anyone have a solid fix for this? I have not experienced any problems with sound on other sites.
My issue is worse: whenever I click back to replay moves the sounds play double. Sometimes the moves sound like two pieces are moving as well as a check has happened. Like every sound available plays at once. I sometimes click back and forth between moves when thinking but with this new glitch this is impossible (and analysis is also horribly difficult to bear). Is this something on my end or Chess.com's end? Is there a known fix yet?

I got a new computer from work and now the sound is broken. No problems before with Ipad, phone or previous PC..
the sound issue has disapeared for me when using the new chess.com site
