The problem with DTS access can be due to various reasons. Some experts say Microsoft did not include a media player and streaming technologies in its latest Windows 10 build and you are required to download a separate pack to use high definition sound and media streaming features. The reason for introducing a Windows OS without a media player and streaming features is linked to the hefty fines that EU levied on Microsoft a few years back for unfair business competition. Since Creators updates make several changes in the system, the older HDMI and High Definition audio drivers become incompatible with the upgraded Windows 10 system. There are different ways to resolve the issue. In this article, we have listed few solutions that have worked for users who faced the same issue after installing Windows 10 Creators updates. Depending on the root cause of your Dolby Access issue, one of the solutions below might fix the issue and get your DTS working again.
