Let's look at this again. In the Sony S5000ES manual, on p70 in my copy, it says:
-When the AV amplifier (receiver) does not support HD Audio...but supports Multi-ch LPCM, LPCM is output.
The setup for this is:
Audio Output Priority: HDMI
Audio (HDMI): Auto
BD Audio Setting: Direct
With a DTS-HD-MA disc, if your receiver cannot decode DTS HD-MA, but can accept LPCM, the S5000ES will automatically decode the DTS HD-MA soundtrack to LPCM and send LPCM to your receiver.
