No sound using Discover

[hydlide]

I am not sure if this is the proper category to post this. But I have been thinking about this for weeks now. There are snippets being posted on facebook where people share their music using discover.

The issue I am having is if I use firefox (35) / IE (latest version), they just don't play any sound here. The "scrubby" thing is moving, like its indicating something is playing, but there is just no sound at all. Chrome on the other is working here.

Soundcloud iframes works perfect. Same goes with youtube videos and any other streaming service I can think of.

I am actually thinking about sending them an email about this issue, since if I have it, others might have the same issue as well.

Let me know if this is just on my end, or any one else has encountered this issue.
Ps, I have this on 2 different windows based systems.

And I know that the service is still beta, just curious if this is on my end.
