Recently, I've been posting here about all sorts of theatre that's available for streaming during the pandemic lockdown. Sounds like fun! But when I actually try to watch some of it... I'm having technical problems.

My Lenovo Yoga tablet won't cast from Chrome. At all. The option just doesn't exist in the Chrome browser on the tablet. The only way to cast anything is to open an app - but the videos I want to watch are on a webpage. In Chrome. Which doesn't have a casting option. Not helpful!

So I go to my desktop computer. It can cast from Chrome to Chromecast. But the result is video only, because "casting tab audio is not supported on this device." I tried Googling that error message, but I ended up getting flummoxed. The Google Help pages don't even mention this error, and other tech blogs are too complex for me to understand.

The Chromecast works fine. It accepts input (with sound) from other sources. It's just webpages (like YouTube.com and Vimeo.com) I'm having trouble with. I managed to watch one video last week, but I had to resort to installing the YouTube app to make it work. But not all the videos are on YouTube.

Any ideas?
