No sound on BBC News
I have suddenly been getting no sound on BBC news videos the last week. Every other website plays sound on videos without a problem except the BBC.
I have unistalled all extensions, cleared the cache and cookies and the problem remains. I have also deleted my profile and made a new one but the problem still remains.
Strangely other PC account users have no problem.

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").
Using "Forget About This Site" will remove all data stored in Firefox from that domain like bookmarks and history and cookies and passwords and cache and exceptions, so be cautious. If you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.
Can't recover from this 'forget' unless you have a backup of involved files.
If you revisit a 'forgotten' website then data from that website will be saved once again.
Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.
- Switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
- Do NOT click the "Refresh Firefox" button on the Safe Mode start window
Tried all those and still there is no sound.
