HEOS problem

[rf1938]

In the past month or so, while using HEOS on my AV10, the Marantz power will suddenly go off after about 20 minutes, usually in the middle of a song. Previously HEOS has worked flawlessly, and I'm not one of those HEOS haters - I really appreciate how it switches the speakers to stereo with music, and back to 5.1 when streaming. Always sounds great. I can't figure out what has changed. Anyone else have this problem? I'm using Qobuz almost exclusively. Outside of this, the AV10 has been perfect.

So it's a full power-down, not just a cutout of the streaming service?

Yes, simply powers down the AV10. Typically all conrolled via my Sony TV remote, never seen the AV10 do this by itself, only with HEOS, and on ly in the past few months.

When you say "powers down", do you mean the unit completely shuts off? Or is it going into standby? For the former, I'd suspect some form of protection is likely getting triggered. For the latter, I'd suspect you've inadvertently enabled auto-standby (or it was enabled by a firmware update or something):

Although you'd think that HEOS playing would count as an audio signal that would prevent auto-standby from occurring, but perhaps not.

It might be another HDMI-connected device triggering standby via CEC. Typical culprits would be a streamer (Apple TV, NVIDIA Shield) or a TV. You could try temporarily disabling CEC on the AV10 to see if that solves the problem.

Yes this is a good thought: is a device connected via HDMI possibly shutting off after a period of time and sending a CEC command? With my AVR, in my experience HDMI CEC commands are ignored when it's playing content over the network (and therefore on the network input), at least for powering off. The AV10 may behave differently however.

I have had a cec problems with one of my Denon on a couple of devices. The Nividia Shield would shut it down or switch hdmi ports.

I've gotten to where I unplug the HDMI cable from my Denon unless I'm listening to what's on the TV. Too many issues otherwise.

Thanks for the ideas - HEOS has worked flawlessly since I bought the AV10, can't remember when, but soon after it was introduced. This is a recent issue with nothing changed in the system. My Sony Bravia usually controls everything, but the only thing that changes is the AV10 powers off completely, after about 20 minutes, TV remains on. Very puzzling, has happened almost every time I listen in the last few months.

So the TV is on when this happens? Every time?

Yes, tv remains on - it's like HEOS sends a message to the AV10 to power off after a set time, around 20 minutes. Once power cycled, it does fine.

It is more likely that the device is going into auto standby. I think you should try to check if auto standby or eco mode is enabled. As updates can sometimes change the settings. Or make sure the firmware is up to date and maybe unplug the device for a few minutes to reset it.

If this only happens with HEOS/Qobuz, then it is probably a software issue and you should contact Marantz.

 

[rf1938]

I'll look at the standby settings, good idea. Thanks.

Auto-standby setting it was! Set to cut out right in the middle of my favorite part of a song. Pondering why this behavior just began with nothing else in the system changing (other than adding a sub). Guess it doesn't matter. Thanks everyone for the ideas and the solution.
