Windows has lost (or more accurately not re-received) the handshake from the receiver, so the device appears absent to Windows, which ultimately means from the audio driver/hardware.
If it's a bug, rebooting XBMC would find the device again, but Windows itself no longer sees it. Perhaps a test - if you can reproduce the error, and exiting and re-starting XBMC still reports that it can't find the device, exit again and try play a test tone using any other player over HDMI.
If that doesn't work, try unplug the device and re-plug, and see if that picks it up again. In theory, that should for sure re-init the handshake.
