Just a quick update: I have been in contact with both Oppo and Yamaha tech support guys, and they are both very polite and helpful. The Yamaha guy sent a modified firmware release for me to test out, hoping that it would solve the issue. However, unfortunataly the new firmware did not
solve the problem. I have sent extensive feedback both to Yamaha and to Oppo concerning my tests results with the new firmware, but I have not yet received any further response from them...
My test results are as follows. (As others have said, the interim fix is to set the Oppo to output LPCM (or Auto) rather than to output Bitstream).Setup
• Player is the Oppo BDP-103EU, firmware 1220, HDMI 1 Out to Receiver BD HDMI In
• Receiver is the Yamaha RX-A820, test firmware, HDMI 1 Out to TV HDMI 1 In (ARC)
• TV is the Sony KDL-46HX855
• Sources are the test audio tracks, and sample audio-plus-movie tracks, on the AIX sampler disk.Test Case #1: Player audio output mode: Bitstream
1.1 When playing the test audio tracks only: => Receiver audio decoder switches to correct format for all source formats (Dolby HD, DTS, Dolby SD, LPCM), channel depths, and sample rates.
1.2 In case 1.1, on selecting a compressed audio track: => Receiver decoder switches to correct format, after delay of about 2..3 seconds.
1.3 In case 1.1, on selecting an HD audio track: => Receiver decoder switches to correct format, immediately.
1.4 Sometimes, when switching from a test audio track to a sample audio-plus-movie track (on the same disk): => Receiver decoder switches to “off”.
1.5 In case 1.4, use the receiver’s remote to toggle it to another input channel and back again: => Receiver decoder switches to correct format.Test Case #2: Player audio output mode: PCM
2.1 As for case 1.1 => Receiver decoder switches to correct format for all source formats (LPCM!!), channel depths and sample rates.
2.2 As for case 1.2 => Receiver decoder switches to correct format, immediately.
2.3 As for case 1.3 => Receiver decoder switches to correct format, immediately.
2.4 As for case 1.4 => Receiver decoder switches to correct format.
2.5 As for case 1.5 => Not applicable. No problem.Test Case #3: Player audio output mode: Auto
3.0 All cases: In the Auto mode, the player apparently selects PCM mode; so all test results are exactly the same as for cases 2.1 thru 2.5 above.Conclusions
• Tests 1.1 thru 1.3 => when only the source audio format changes, the Receiver can always detect the proper audio format.
• Test 1.4 => when both the source audio & video formats change at the same time, the Receiver (sometimes) cannot detect the audio format.
• Test 1.5 => when the Receiver input channel is changed, it can detect the audio (and video) format.
• Test 3.0 => Receiver may not be not sending its EDID codes; or the Player is not seeing them.
