ARC is not for transmitting audio from the receiver to the TV in standby.
This receiver does appear to have HDMI pass through in standby mode, so it should work. It will need to be configured in the receiver's setup menu to allow this to happen. However, I found that this receiver seems to have the same issue my pre/pro does, depending on the source device - the TV may not be able to internally decode all audio streams so you may be missing some or all audio that is being passed directly from the source.
