I also had the same problem as you and Cara. my laptop is HP, I have a Samsung TV that works perfectly well with HDMI both audio and picture. Once I hook to Sony sound comes out from the laptop regardless of how many times I choose TV speakers and enable them. So, my solution, like Cara's was that every time I hook my HP to Sony, I go to sound mixer and disable my laptop speakers. Automatically the Sony speakers start working afterwards. Now, to listen to your laptop speakers again, all you have to do is again go to volume mixer icon, choose laptop speakers and allow it to configure again. The problem will solve itself and show u a "fixed" message when it is done. The downside is every time I rehook it to Sony I have to disable the laptop speakers again, then reinstall them once I am done. Hope that helps.
Former RT Moscow anchor Stacy Bivens, and other former RT journalists speaking under anonymity according to BuzzFeed, said they regretted working for the network, citing their dislike of the network's use of propaganda. Bivens, for example, was explicitly asked to go to Germany and procure a story proving that "Germany is a failed state". When she rejected, other reporters were sent instead.
