I just switched to the stable docker since my Phaze plugin stopped working. Unraid installed 3.0.7300 and on the dashboard homepage it said a newer release of Emby was available. I was able to upgrade Emby by running "docker exec EmbyServer update" from the command. I don't know why it didn't pull down the latest release at time of install or why unraid didn't say an update was available.
OopsAllBerrys,
What kind of hardware are you using? On my machines I have both refresh rate match and HD Audio passthrough working. I have also not experienced a loss of settings upon reboot.
I am running a Radeon HD 6450. If I turn match refresh rate off, HD audio passthrough works at 60Hz on both the LT template and the generic VM. It seems like this is a driver issue from AMD after some Googling. Looks like I need to find a cheap NVIDIA card that will support HD audio passthrough at 24 Hz.
With the LT template, OpenELEC doesn't like changing the refresh rate to match the video and DTS-HD and TrueHD work. I've also run into the problem where I will reboot the VM and all the settings for Kodi are reset (skin, weather addon, etc.).
With a generic OpenELEC VM, OpenELEC changes the refresh rate fine to match the video; but DTS-HD and TrueHD do not work.
I would recommend using PlopKexec instead of the standard Plop; it boots up much faster, 20 seconds vs 5 minutes for Plop.
