I have searched around these forums and found lots of interesting bits and pieces that I am grateful for.
Since upgrading from previous Yamaha AV I have a few issues. One being ARC wanting to put to Audio 1 each time I turn on my Blue-ray player - I think I found the answer to this and have switched off CEC and perhaps I also need to just give up on ARC and use an Optical connection from the TV.
I have a cable box and blue ray all connected to the AVR
I am experiencing volume spikes and I dont know if it is the remote, or ? Happens when using the [blu] ray player. (mixed up in this effort to get to AV1) Sudden jumps in volume and then shuts down speakers and at time scrambles what is coming out of different speakers. Another example was I played a DVD and the volume level was so high that it sent a 'shock'through the system. So it looks like I have to adjust the volume right down low before starting it up in case this is something regular. Now that I have turned off CEC for the blue ray player, perhaps the problem is gone.
Is the speaker shutdown a safety thing?. Is ARC and CEC linked together? If I just use a Optical cable from the TV to the AV, will I still get reasonable sound with the AI taking care of things?. any pointers would be appreciated.
1. The RX-V and RX-A models have some similarities (some even share the same cabinet, front panel, and power specs), but I'm skeptical that they share the "same internal gadgets" (UNLESS you meant features
, not components
). There may be some differences aside from warranty coverage and the notorious fifth foot, e.g. the AM/FM or FM-only tuner in the RX-A2080 and RX-V2085.
2. ARC and CEC are often coupled in some manufacturer's devices. Most likely, your TV's HDMI-CEC is telling the AVR to switch to the HDMI-ARC input after turning on, though you've told the AVR to switch to another component. I have the same problem with turning on an Apple TV and a Samsung TV -- the Samsung turns on more slowly, so 9 out of 10 times switches the AVR to the ARC input. Even using the Yamaha SCENE button isn't enough (though that's my recommended way to initiate power on with all components). I would guess it's NOT your BD player's fault.
3. Volume spikes are worrisome. I would use the AVR setup to set initial volume at a lower level than you may desire. I have mine power on at -40 db though I will play music or movies from -30 dB to -20 dB. That way I can turn it on and play music at a quiet level without touching the volume (actually, using a Chromecast or Apple TV, I don't have to even be in the same room as the AVR, I just connect and play).
How is the BD player connected to the AVR, via HDMI? A particular DVD shouldn't be "louder" unless it was very badly mixed. What WAS the DVD you were playing?
Check all your cabling. Are your speaker cables properly terminated with no stray wires exposed? Are you using banana plugs, or bare wire? Are the HDMI cables in good shape, none of them kinked, bent or worn? Are connectors in good shape?
4. ARC and S/PDIF (optical cable from the TV) have roughly the same limitations: compressed 5.1 sound, or uncompressed PCM 2.0 (as Piomaniac reminded me, ARC can send DD+ which can include 5.1.x). If you can run S/PDIF optical to your AVR from the TV and disable the TV's CEC feature, that may eliminate the TV's tendency to mandate the AVR switch to the ARC input, but will also remove the ability to turn the TV on and off from AVR activity. Older Yamaha remotes had a separate "TV Power" button, check if yours does.
Seems like Yamaha announces new product news in March, April timeframe (
correct me if I'm wrong), if not during CES (January), so based on earlier reports that Yamaha will wait until 2020 for new models featuring HDMI 2.1 features, I wouldn't hold my breath on new model unveiling. We could get a surprise, though.
