Thanks for the input. Upon investigating further, I think that I was wrong about the old TV decoding anything other than PCM audio, and what was actually happening was that the WDTV was detecting when the AVR went into standby and automatically
switched its audio output setting to PCM for the newly detected output device. For some reason, with my new TV, this is not happening.
In summary: I recently upgraded my old, geneic 'no-name' TV with a brand new Samsung LED unit. Prior to this upgrade, everything worked perfectly. The WDTV is connected by HDMI to an AVR, which is then connected to the TV via HDMI. For some reason, my WDTV is failing to detect the change in audio device when my AVR is powered on or put into standby. Whereas before (with my old TV), if I was watching something with DD/DTS audio on the WDTV with the AVR turned on, and then put the AVR into standby (thus passing the signal through to the TV), the WDV would automatically detect this change in output device and switch its audio output to what was supported by the new output device (PCM).
I also have a DVB TV set-top box plugged into the same AVR, which outputs DD (2.0, 5.1) on selected channels, which does detect when the AVR is put into standby and changes its output to PCM for the TV. Which tells me that this isn't an issue with either the new TV or the AVR.
In the WDTV audio output settings, I've selected 'Digital Pass Through via HDMI Only (HDMI)'; and when choosing 'auto-detect' with the AVR switched on, the WDTV correctly detects all available audio codecs, but then fails to switch its audio output to PCM when I put the AVR into standby mode. Likewise, when I choose the auto-detect option when the AVR is in standby, the WDTV correctly detects that the TV only supports PCM audio. But again, the WDTV remains in PCM mode when I switch on the AVR.
I've tried a hard reset, firmware downgrade, changed HDMI cables around twice; and now I'm running out of ideas. I just don't understand why the WDTV was automatically switching its audio output format automatically with an older, unbranded cheap TV, but not with a new Samsung TV which is supposedly superior.
