Can't watch streaming site because of sound issues and weather alert

So, for a couple of weeks, every time close a channel and select another one, doesn't matter which one, there is no sound.  I have to reload the page, go find the channel, and then the sound will work.  I've logged out, cleared my browser cache, still have to reload.  Does this on more than one device.

As if that wasn't annoying enough, today, every time I reload the page, it thinks I'm just logging in, and within a couple of minutes, shows me the weather alert.  So, it goes like this:

Open page, select channel, all is well.  Weather alert comes up.  When it closes, no sound on the channel.  Reload web page, select channel.  Site thinks I just logged in, so within a couple of minutes, the weather alert again.  When it closes, again no sound.  Reload page, over and over.
