Sound stops playing in YouTube - Chrome

Do some more tests:
-does it happen with a different user as well
-does it happen with a different browser as well
-does it happen with any video or just on YouTube.com (any vid. on YouTube?)?

It's not easily practical to test with another user, however as far as my testing goes, it appears to be limited to YT and Chrome. Not every video, but a fair number, enough to annoy me into posting this question :)

You need to be sure about what you see. Do some tests, make sure, or you will get all sorts of recommendations that you will be asked to try. It pays out to invest some minutes.

Interesting, given that a page reload or restarting the video resolves the issue we can likely rule out mistaken muting of the video (both muting of a tab in Chrome and mute on YouTube persist on reload).

Could possibly be two audio sources conflicting? Do you recall having any other open tabs w/ ads that started playing audio or something else like notification tones for an instant messaging service?

The author wrote "It's not easily practical to test with another user" - oh yes, it is. If you say, it happens with chrome and on YouTube, logon as other user, open chrome and use it on YouTube.com - easily practical, one minute of effort. Before we have the result of that, no actions should be tried.
