Hi Shane,
It's related to our intel gfx driver.
We bought the same Yamaha RX-V1800 and experienced the same problem.
I was doing extensive (black box) debugging on it these days, and
found that the following process can produce sound on Yamaha:
startx
xrandr --output HDMI-1 --mode 1920x1200
In fact the default 1920x540 mode is the only mode in which Yamaha
cannot produce sound. Our intel gfx maintainer confirmed that it's
actually the 1080i mode that is not supported yet.
Thanks,
Fengguang
