Interesting HDMI Problem: OPPO UDP-205

I have a McIntosh MX122, OPPO UDP-205, and a Sony Bravia OLED.   The OPPO is connected to the MX122 through both an HDMI connection (BluRay "in") and RCA patch cables (CD "in") so that I can use the OPPO DACs for listening to audio CDs.

The Sony is connected to the MX122 through the Monitor 1 output.

I've been having intermittent audio dropouts when using the analog connection to listen to audio CDs on the UDP-205.   I've finally traced the problem to the Sony Bravia.   The Sony implementation of Consumer Electronics Control (CEC) is called "Bravia Sync."

In the Bravia Sync menu, Sony does not provide an "OFF" setting.  They have "Enable" and...nothing to turn CEC "OFF."  What they have you do is delete the HDMI equipment list from the Sony CEC sub-menu.   This does NOT turn CEC "OFF" - it simply hides the expanded CEC menu as you no longer have an equipment list to control, while leaving the CEC feature / circuit active.

The CEC is active even when the Sony is turned "OFF," because, in reality - the Sony is on standby and only the screen has been turned off.  The electronics are still active because the Sony can be programmed to automatically turn itself "ON" when it senses a different piece of equipment turn on through the CEC / HDMI circuit.

What happens with the Sony turned "ON" or "OFF" is that the Sony constantly looks for equipment through the HDMI connection.   It's randomly looking for a friend and sending out a handshake signal.  This disrupts the UDP-205 as it's processing audio through its DACs and it momentarily times out to send a "Yeah stupid, I'm still here" response back to the Sony.

Haven't quite figured out where to go from here...as I don't have a resolution to the problem - but, I thought this might help someone else if they're having the same type of problem.

Good news bad news

Just bought a Sony XBR 900e TV and had the same problem. My 2012 Panasonc had no issues.I own a Marantz 8802a pre-pro it has two HDMI outputs. All I have to do is use HDMI 2 which is not connected to any devices and all works well.It's to bad that the movie industry is so concerned with pirating. I also had an issue with my Logitech universal remote and a new 4k apple TV. I managed to fix that by re-setting my the Sony back to factory settings. It seems TV manufactures keep trying to build as much into a TV so we will not use another manufactures device. I would never use a TV's streaming apps, or other builtin apps. That's what I buy a Roku or Apple TV for,they do it right.

I have had the same problems. Audio cutting out briefly. Only started when my Pioneer plasma of 15yrs decided to die. Replaced with Sony KD65A1. Only solution so far is to unplug hdmi. I don't really want to keep Sony TV screen on whilst listening to music.
A bit disappointed with this set up but what else can you do. Never had the problem with Pioneer. Also, on a different gripe, I'm still not sure if the oppo 205 sounds much better through anologues into my Denon avc a1d than an optical off the 205 and letting the Denon do the DAC duties. The Burr brown DAC in the Denon has a lovely sound. I find the Oppo harsh. I'm going to change out levels from Oppo to see if that improves things. So far, not hugely impressed.

With a suggestion from Dan Wright (Modwright) and this thread I was able to solve my Oppo 205 issues simply. It's strange how even when the Sony television was off and the only connection between the Oppo and TV was through a Marantz 8802, also powered off, I would still get the drop out in sound. So far the simplest solution was pulling the hdmi cord from the back of the Oppo. I haven't tried the other solutions on here...but thanks to all for the investigation and advice....

Newer Sony TV's remain ON even when powered down for firmware updates. So the unit is never really OFF. When your OPPO is playing music, it sends a signal to the HDMI output of the player. The "HDMI Handshake" between the Oppo and Sony does not connect properly and causes the dropouts. You'll can either unplug the HDMI, turn on the TV and use the Gracenote function or use the screen off function on the Sony TV remote.

No such issues with my 205 and Sharp  60" LED. Started playing CD, turned on TV, one short blurb from Oppo, nothing more while TV playing or with TV turned off again.
Maybe my older Sharp not smart enough :)
