This is an ongoing problem for many of us and it seems to only be with
Sky News as part of the news lineup. One would expect better answers
from Google at this point.
This has been an ongoing problem for the past year. Last week I had Sky
news with audio all week, today again no audio. All the other news
channels have audio except Sky News, yet Google seems to be oblivious.
It's been an ongoing issue with me too. Sometimes Sky News will have
audio and then I'll go a week or more with no audio. All the other news
outlets play just fine.
