Using Oppo 105 for Audio from Cable Box?

Oppo released a beta update (3/26/13) that seeks to address the audio synch delay:

* Added a feature that allows the adjustment of the audio delay time within the range of -100ms to +100ms. This can be set under "Setup Menu"->"Audio Processing" -> "A/V Sync", and the delayed time will be applied to all output terminals including HDMI 1 and 2, Coaxial, Optical, and 7.1 outputs (including the Stereo outputs of the BDP-105).

* The actual audio delay effect might be different for each of the output terminals due to the different audio process algorithms and signal paths used for each output. Please adjust this setting based on the actual output terminal in use.

* The negative adjustment values are for cancelling out the audio delay that the player automatically applies. Depending on the video source and the time it takes to process the video, the main decoder chip automatically applies an audio delay in order to optimize audio video synchronization. The negative manual settings reduce the automatic audio delay, while the positive manual settings apply additional delay. Any negative value setting beyond the player's automatic delay will be treated as completely cancelling the automatic delay. For example, if the "A/V Sync" value is manually set to -100ms and for the current video source the player applies a 70ms automatic audio delay, the final result is that the 70ms audio delay gets cancelled and the audio is not delayed at all. It is not possible to put audio ahead of video using this setting.

I take HDMI from a DirecTV HD-DVR to the HDMI port of the Oppo 105, HDMI-1
out of the 105 directly to the projector and HDMI-2 to a monitor for video,
analog XLR stereo and RCA 7.1 to a Cary 11a processor for audio. The result is
excellent audio and video.

I often listen to balanced stereo leaving the other amps in standby mode, but
that's just to save energy.

Thanks db. The question is "does it sound better with the audio being converted to analog via the 105 vs via the DVR or processor?"

Thanks Edwyun

Do you know how well this works? And is it necessary at all if one if using Cable Box to 105; HDMI from 105 to TV; analog (interconnects) from 105 to amp?

Jfz, the Cary 11a for all its bugs has a reputation for fine audio quality, a reputation deserved in my experience. Thus, although I don't use it, I'm confident HDMI-2 taken to the Cary would produce excellent audio. Analog from the 105 to Cary inputs set to bypass certainly produces excellent audio. Both will substantially exceed the analog capability of the DVR. You would need a processor with an exceptional analog stage to better the analog from the 105.
