On Windows 7, in YouTube web client (in latest Chrome) - videos play, but without sound. IIRC, they used to play with sound some days earlier on the same machine. Pretty sure I did not change any config opts in between - had no reason to.

Yet, at the same time (now, when YT has no sound), VLC player works fine, has sound.

Had similar problem earlier on another Windows 7 machine of sound getting disabled intermittently. Tried a lot of things in Control Panel / Sound option, but mostly did not work then, nor now.

Is it 100% limited to youtube and other online web players function (Vimeo, etc.)? – nerdwaller Apr 6 '13 at 23:18
Did you set Chrome to mute on the volume mixer? Do you use Chrome Toolbox? Some resources from searching on Google:…,!topic/chrome/NENAi7jc9fE (about the same as the previous link),… (volume mixer) – Apr 6 '13 at 23:24
Youtube has its own volume control did you check that? – cybernard Apr 7 '13 at 1:39
Hi, thanks to all who answered. – user214769 Apr 7 '13 at 17:38
cybernard: Turns out you were right. I checked the YouTube volume control, it was set on mute for some reason. Don't think I did it myself. So it looks like the issues given in the links mentioned by others above, also have a part to play in this problem - i.e. only the Chrome volume seems to be getting muted automatically. Weirdly, when I went into the Windows Volume Mixer, I saw the section for Chrome, which was set to muted, and it had a message that it was automatically muted ... not sure how that happens! – user214769 Apr 7 '13 at 17:41
