You can get Ardour for Windows, but may have to pay something for it. I may set up a subscription again as I get good value from it. It's love to see such projects on Steem so I can reward them with votes.

I can see the Soundcloud player on another PC and my phone. No idea why you cannot. You are not missing much :)

Are you using Steempeak? That seems to have an issue with the html, but it works on Steemit and in Steem.

Yes, Steempeak.

And yes, it works on Steemit.

Thanks!
