Just got my Vero 4k + (Not off to a good start)

The information you need for setting the audio can be found in the following link. The option you describe as using before would be the ‘transcode to AC3 option’.

To get that option you would set your settings to “advanced” then in system>audio you will set…
Number of channels>2.0
allow passthrough> (enable)
dolby digital capable receiver> (enable)
enable dolby digital transcoding> (enable)

You click on where it says “standard” a few times until it changes to the level you want.
