The audio is currently RCA analog out to an integrated's RCA in. The video out is HDMI to the TVs HDMI in. Any thoughts on this issue would be appreciated. I'm off to see if I can make the Search functionality work better/at all.
First of all, welcome to AVS and to this thread!
HDMI is not exactly "user friendly", and at least part of your problem is due to this.
HDMI is an end to end protocol with copy protection. That means any time the set of devices CHANGES in the currently active HDMI chain, there has to be a new "handshake" to reset the HDMI chain to the new configuration. The player pauses playback during an HDMI handshake so that you don't miss content. You wouldn't have been able to hear the content anyway (even over your Analog audio connection) as audio and video get muted during a handshake (while copy protection is re-established). If you check the time code display in the Front Panel you'll see that playback is truly not advancing, rather than play continuing with no audio output.
So turning the TV ON/OFF while it is connected via HDMI will result in a new handshake. The minimum time for a handshake is about 2 seconds due to delays built into the handshake spec (designed to give even slow devices a chance to react).
Now that said, PLAYBACK SHOULD NOT STOP. It should PAUSE and then resume in a couple seconds. If you have a repeatable case where playback of a CD is STOPPING due to turning the TV ON/OFF (i.e,. the time code goes away in the Front Panel display and the player is now in STOPPED state) please write up what's happening -- including how things are connected -- and email that to OPPO Tech Support. NOTE: There is a known bug where SACD playback can Stop due to an HDMI handshake in certain configurations, but that should not be affecting CD playback.
To avoid all this, a lot of folks leave their TV ON during music playback and use Pure Mode (Pure button, upper left on the remote) to blank the video output.
There is another potential problem which can cause loss of audio when you turn the TV OFF -- although it should not result in the player switching to STOPPED state.
The root cause is a bug in the AVR which is triggered by a behavior in the TV when it is turned OFF. The bug in the AVR is that it is not properly detecting the TV really has been turned OFF, and so it tries to get copy protection to talk to the TV -- which can't happen since the TV is OFF. (Technically this is a bug in "repeater processing" in the HDMI implementation in the AVR.) Check the owner's thread for your AVR, because this should be a common complaint and there may even be a firmware update for the AVR to fix it.
The behavior in the TV that triggers this -- and the reason it doesn't happen using that AVR with *EVERY* TV -- is that many modern TVs keep their last-used HDMI input "live" even while the TV is supposedly "OFF". The bug in the AVR is that it can't distinguish the case of the HDMI connection being live but the TV actually being OFF.
The two most common reasons TV do this is in support of HDMI CEC (remote control of one device from another via HDMI), and HDMI Audio Return Channel (ARC).
Since you have the DirecTV and the TV itself both turning on together, it is possible that you are actually using HDMI CEC to do that, or you may simply have it enabled even though your are not using it.
To CHECK if this is the problem, temporarily DISCONNECT the HDMI cable from the AVR to the TV, and now see if your CD playback works normally. If it does, then you know the inability to get audio to pick up again after the TV is turned OFF (and after the couple seconds while HDMI gets its act together) is due to this confusion in the AVR.
If this is the problem, there are several things to try. First, see if you can turn off HDMI CEC stuff in both the TV and the AVR. This may be called some random marketing name, but again, it has to do with devices turning on/off automatically or changing inputs automatically because of something being done on some other HDMI device. For some TVs HDMI CEC (and often also ARC) may only be implemented on one of their HDMI inputs. In which case the easiest way to disable that stuff is to switch to using some other HDMI input on the TV (again this is for the HDMI path from the AVR to the TV).
Failing all that, another common workaround is to remember to switch the TV to a DIFFERENT HDMI input (perhaps one that's not even cabled) BEFORE you power off the TV. Since the HDMI input from the AVR is no longer the last-used input, the TV may let it shut down fully when you now power off the TV.
Again, this is all in aid of getting the audio to come BACK after you turn off the TV. There will still be the couple seconds handshake pause when you change the status of the TV, but the audio SHOULD come back after that. If it doesn't, then working around this type of bug in your AVR (or getting a firmware fix for the AVR) may be just the ticket.
Come to think of it, your issue with the player STOPPING when this happens could be due to enabling HDMI CEC in the OPPO. I.e., it is getting a Stop command from either the TV or the AVR.
You can disable HDMI CEC in the OPPO's own Setup menu (Setup > Device Setup).
