yes, everything comes back nicely (and i don't use dr hdmi or anything similar).
rdp is also fine as it's a network protocol, it doesn't require a display.
this is how it looks via rdp (option remote audio playback set to "play on remote computer") with avr and tv both in standby (avr has passthrough enabled).
you can see that audio properties (supported channels, frequencies and compressed formats) change to what the tv supports.



i use a password for my windows account so after disconnecting rdp i just have to login again when i want to use my home theater.
i don't know, maybe vnc or some other remote access utility wouldn't require that.
