Good for you. I can only hear like every fifth piece move and it doesn't matter if it's a brave, chrome or edge.
I have no sound

Windows. Chome Browser. No sound either.
I get sound from Youtube or Windows notifications but no sound from Chess.com and also latest chess move doesn't highlight.

It definitely has something to do with the speaker, bc the sound works on my laptop. But i cant figure out why it wont play from my PC speaker, bc the speaker works for every other sound.

not getting any piece movement sound, one of the setting will change the sound and the other will not make any sound
Getting all other sound just not the piece movement Help I dont like not hearing my moves
Have been without sound for a few days now. Seems like it is widespread. I have gone ahead and joined Lichess, with I am sure many others will do. Hope chess.com gets it fixed.

Website or app? If the app which one and which version?

I get sound in game review but when playing a game sometimes I get sound and sometimes I don't. Sometimes I will have sound for the first few moves and then it stops. Seems completely random.

I found a workaround, albeit a slightly annoying one. if i play a youtube video or music on itunes in the background, the sound works. it seems like the problem is that the speaker doesn't register the short sound of a piece move every time. but if it is already playing other sounds, it will always play it.
I get no sound in Brave but I do get sound in Chrome and Firefox
