Good thing I din't dump my elderly WDTV Live+ , just connected it again to my HT setup. Despite having sluggish UI WDTV plays every possible file format flawlessly including Dolby TruHD and DTS HD Master. And 1080p/24 to top-up already nice set
Yeah I used to love my old WD TV Live as well - unfortunately it eventually died on me. Went for the Roku because of 4K+HDR support + Plex. On the sound side I am not really impressed because of the sync issues and lack of passthrough of old formats (DTS HDMA and Dolby TrueHD are indeed old).
Echoing the issue with DTS. I have experienced an increase in such problems ever since the 7.5.1 upgrade - and build 4111 (the latest) has made things worse as far as audio syncing goes. On the plus side they did fix my HDCP issues, so there's that.
Being a new Roku Premiere+ user, I will give them the benefit of the doubt and have some patience for them to fix this - but my patience only goes so far. At some point I will be prone to run off to a competitor like FireTV or Nvidia Shield (very expensive, but supports DTS-HDMA passthrough and many other sound formats natively).
