Unusual Streaming problem

I have just installed the Spotify App on Windows 10 but since I did this Radio streaming has been acting up. I use the TuneIn App to stream radio stations but this has recently been updated by Windows Store and no longer works.

I put the lack of streaming with TuneIn App due to the update so resorted to using individual radio stations web player. Now here is the funny thing I can see data being downloaded by the radio player but no sound then after an hour of leaving the tab with the web radio player open it suddenly bursts into life and the stream can be heard. I say an hour I haven't timed it but this all coincides with the installation of Spotify and TuneIn update.

Any ideas what is going on it was working perfectly last week.

Solved it is Bitdefender Free blocking the app and web player. Turn off protection in BitDefender and bam stream jumps into life. Please move this thread if it is in the wrong place and may help someone else getting blocked streams.
