Have a Panasonic TC-P50ST30 that apparently only passes the 5.1 signal unmolested from the internal tuner on the TV. Devices connected via HDMI to the TV set are downgraded to 2 channel when output from the TV's optical. Any workarounds besides a new TV others have found? Live with the 2 channel input to the PlayBase?
"*When audio from other equipment connected to this unit via HDMI is output using “DIGITAL AUDIO OUT” of this unit, the system switches to 2CH audio."
