Hello, I used Realtek Unlocked Drivers on Windows 7 and they worked fine. Both DTS and Dolby were working good. Now I upgraded to Enterprise 2015 LTSB N and they don't work. I always get 'Failed to play test tone' error. People said that newer builds fixed the issue, but LTSB is build 10240. Is it possible to somehow upgrade the Windows or is there something else I can do to get DTS and Dolby.
