I am continuing my travel around your OS, for which again my thanks for producing.
Playing audio and video from files saved via VLC (Default App) confirmed.
Playing audio and video from inserted CD and DVD via VLC (Default App) confirmed.
No audio from Boom Radio, a UK radio station (https://www.boomradiouk.com/)
No audio from YouTube.
I have checked all that I know. Basically, volume in task bar and volume in VLC.
I must be missing something (can't see the wood for the trees)!!
Any help will be appreciated.
Thanks
