We have noticed the same results in our environment Brian.
Windows 10 users are not affected on Internet Explorer 11 as it has built in flash and doesn't use the Adobe Flash ActiveX.
Edge and Chrome work fine because they use HTML5 to display the video.
The older version of the Flash Active X plugin also works successfully - however v30 patches security vulnerabilities - so obviously not a good security practice to roll back to an older version.
The affected environment is Windows 7 users - Internet Explorer 11 with v126.96.36.199.
We also found that this affects all the videos shared in Office 365/SharePoint as well.

I've been investigating a similar issue here:
In that instance, toggling the EnableInsecureByteArrayShareable flag *did* resolve this. Apparently there's some handshake stuff happening in the background that used Shareable ByteArrays for inter-process communication. The team working on the actual video technology is actively engaged and working to remove this dependency.
I suspect that in your instance, a similar approach may actually work. The mms.cfg file needs to be saved as UTF-8 or ANSI (we see a lot of issues related to people saving the file with more esoteric encodings for some reason), and you would need to either whitelist the right set of domains, or just enable the shared bytearray feature across the board.
I'd recommend just doing a double-check, making sure that mms.cfg is in the right locations, that the file is saved with a supported encoding, and that you have the right directives and values specified.
See Page 54/55 for details on those directives:
If that doesn't help, it would be helpful if you could send me a link to a skype broadcast that demonstrates the problem, if that's possible. Feel free to shoot me a private message -- just click my username.
It's not about built in Flash, post Windows 7 OSs don't use Adobe Flash at all for Skype broadcast instead they use HTML5 streaming media, therefore, we don't see this problem on Windows 8.1 or Windows 10.
Windows 7 doesn't fully support HTML5, thus it uses Flash for Skype broadcast:
System requirements are stated in the following documentation:

@jeromiec - Thank you very much for your assistance!
Adding EnableInsecureByteArrayShareableDomain=*.broadcast.skype.com to C:\Windows\SysWOW64\Macromed\Flash\mms.cfg resolved the issue.
I was able to resolve the issue using your fix. I tested first by enabling across the board which fixed it. For security sake, we will locate the source domains and enable just for those domains.
Thank you for the quick turnaround!
Sweet, glad I could help!
Issue is resolved with latest Adobe update v 188.8.131.52
Yes, thanks for the reminder. Tuesday's release (in tandem with an update to Microsoft's video player) removes the dependency on the functionality that was impacted, and gets video playback working again. You shouldn't need the mms.cfg flags anymore after updating to the latest Flash Player, and we'd recommend that you remove them from your deployments.
Could you please update the kb number which needs to be installed with Flash Update
That's a great question for Microsoft. Flash Player is a built-in component of Internet Explorer and Edge. Microsoft handles the packaging and distribution of Flash Player through Windows Update.
