Additional information:

I have 7 google casts in the house (1x home, 2x mini, 2x audio, 2x chromecasts) and they're shown in my frontend. I've always had reading from socket errors in the logs, but it's occasional and it always resolved itself after a while.

Since updating to 0.78.x after a couple of days, my mediaplayers will eventually come up as Unavailable and stay like that. All automations around the media players never fire (e.g. automatic sleep timers fail and podcasts are played all night!).

A reboot fixes the issue, but only for a couple of days.

Hi CheeseySandal

Did version 0.79 fix your problem? Because for me it did not. My chromecasts still become unavailable for a while.

[CheeseySandal]

It did I'm afraid.

@nelbs please open a new issue for your case. Chromecast component is complex, the previous fix only address particular configuration.

When you open the issue, please provide your debug log, config, and what type of Chromecast device involved. Chromecast, Google Home, or Smart TV, etc.
