Rossini DAC accidentally switching on

I have a Rossini APEX DAC with Rossini Clock and Scarlatti transport, and these are usually left on standby.
Rossini s/n RSD51932, Front & Control board v2.10, Net board v1.4.4 (523)
It is connected via an ethernet switch to my home network.
In the next room I have a TV and Humax Aura video recorder also connected via the same ethernet switch. When the recorder starts a recording it switches on the Rossini completely unintended, and I can only prevent this by disconnecting the Ethernet cable. I have looked through the Humax settings and can find nothing that changes this behaviour. What could be happening here?

When on Standby, the Rossini (like all dCS Streamer/DACs) will ā€œWake-on-LAN activityā€; which means it will turn-on from Standby when there’s Ethernet traffic on the LAN thats specifically targeting your Rossini’s Ethernet MAC address.

Clearly your Humax Aura is doing something on the LAN it should not be doing thats turning on your Rossini.

Hi @OrganGrinderMike

Can you drop me an email at [email protected] please - I’d like to get some logs from your Rossini immediately after it has been powered on by your Humax and hopefully we can see what’s going on … I’m not aware that we support simple Wake-On-LAN (my understanding was that we didn’t) so I’m curious as to what’s going on here…

Cheers

Phil, ironically you can test it out with Qobuz Connect;

  1. Have Qobuz Connect point to some other device
  2. Put the dCS to standby
  3. Select dCS on Qobus Connect ← that’ll wake the dCS from Standby

This also works for Spotify Connect (which is how I found out years ago that the dCS wakes-on-LAN)

Yes my Vivaldi will turn on if I happen choose my Music Room zone in Roon when I was actually intending on selecting the whole house system zone.

Hi @Anupc

That’s absolutely expected operation … if you put one of our streamers into normal standby (where it can be woken by the IR remote or Mosaic) then quite a bit of the unit is still actually powered and running - the streaming board is still fully awake so that it can respond to Spotify / TIDAL / Qobuz Connect requests, AirPlay, UPnP, Roon etc.

Those services don’t use Wake-On-LAN though (as far as I am aware) and there’s also no valid reason that the Humax should be sending a Wake-On-LAN packet out to the Rossini if we did (or to any other device on the network).

Mike contacted us a little over a year ago with this but then said that turning off CEC on his Humax resolved the issue so that was the end of that discussion but if it has popped up again then we’re really rather keen to get logs from his unit so we can see what’s going on…

True, they don’t actually send out WoL magic-packet frames as such, so I assumed it’s not a traditional Wake-on-LAN with the streaming board.

Strange. Curious why the CEC setting would affect the Ethernet function (you meant the HDMI setting, yes?), but I wouldn’t be surprised the Humax is spewing crap over the LAN (it’s an Android based device after all :rofl:)

Hi Anup! :smiley:

Absolutely - the streaming board just sits waiting for something to talk to it using any of the different protocols that it supports and then when it gets something sent to it then it wakes the rest of the system up.

Oh I totally agree - incredibly strange and I also assume that it was the HDMI CEC but have no idea why it would have any effect on Ethernet traffic…

I couldn’t possibly comment… :smiley:

If I was a betting man I’d put my money on the Humax sending out some random UPnP command that’s kicking the Rossini into life but hopefully we can find out from the logs…
