I've got a Raspberry Pi with Xbian and XBMC installed that works perfect through HDMI when I connect it to the TV set. Video and audio are nice, but I've tried to set up it with my AV receiver without success.
The Raspberry Pi (Xbian and XBMC again) is now connected to the AV Receiver through the "HDMI In" input, and the AV Receiver "HDMI Out" goes to a 720p projector. Although the video works, there's no audio anywhere.
I've tried to apply previous solutions, such as this one in which the config.txt should have the following lines
And even tried forcing EDID Audio:
# HDMI Force EDID Audio
# Pretends all audio formats are supported by display, allowing passthrough of
# DTS/AC3 even when not reported as supported.
But with no success.
One more thing. The AV Receiver (Sony SDR-K890 with a 6.1 surround system) has two HDMI inputs. The one I try to use, "Video 2", should be the one working.
I currently use the other one, labeled "DVD", that allows me to connect an audio cable from the 3.5mm RPi connector to 2xRCA (Left/Right) connectors on the DVD Audio part of the AV Receiver.
If I do that and change XBMC audio settings to Analog / 2.0 I get sound. But this, of course, is not the ideal solution. I'd like to take advantage of HDMI and surround sound. Any ideas?
