Ok, I opened the Audio controls and it had Speakers as the the first selection and the sound card for the second. (See attachment)

Both of them can not be the same because as I switch one, the other switches to the second alternative.

So I switched them the other way around and still got nothing. Video shows but no sound.

Switched them back to the original settings and now they play fine.

Thanks.
