I am liking the new Google Music cloud player feature. I have my GTV hooked to a Sony STR-DH800, but when i play music it seems to be sent to the receiver as LPCM 5 channel with no sub woofer. Is anyone else having this problem? Is there a way to get the GTV to send it as 2 channel and let my receiver do the surround separation.
