All audio from online radio streams has stopped !

I have been using the TuneIn App on my Windows 10 Desktop for years without problem but just recently I lost the sound. It looks fine with no errors but it is as though the volume has been turned to zero !

I thought it was a problem with the App but when I try to listen online via the Radio station websites themselves, I still get no sound and no errors.

The only streaming radio that I can hear is via the BBC Radio website - that works fine !

I haven't changed anything to coincide with this. I have recently installed a new sound card but that has made no difference.

Any help appreciated.

Turned out to be BitDefender Anti Virus that was blocking streaming radio. No idea why, no option to stop it so BitDefender is in the trash and I'm back with AVG !!!

I was given a old laptop with Windows 2000, I loaded Bitdefender on it, Bitdefender blocked IE.
