Not sure if this is a problem that has been raised before but I thought I would ask.

I have a Studio.  It is feed by a single AES cable from a Mutec USB 3+.  the AES is the only input cable into the Studio.

I run my audio volume via the Studio Remote.    Twice in the last 10 days, as I have been sitting listening to music, the audio has gone off because the Studio input selector has Automatically switched from AES to LAN.   On both occasions the remote remained untouched and I was the only person in the house.

Aside from having a ghost, does anyone have any suggestions.

I sometimes have the issue with my Studio that it switches to LAN automatically while I am using AES input. I think in my case it has to do with my children were using spotify with the SHD streamer. And if they do not cleanly disconnect after using the spotify app, the app might activate the spotify plugin of volumio and therefor switches to LAN automatically later. This seems to happen when they open the spotify app again. But this is only a theory that I have, I did not test it in detail. It only happens very rarely.

I experienced this behaviour just one or two times on my SHD. Didn't touch the remote but input switched.

I wrote a volumio plugin for input default values for the SHD series, so I'm a bit familiar with the code that switches Inputs. I didn't remember seeing anything switching the input except the remote.

When I have some spare time I'll have a look.

When you start a track via volumio (or upnp, and I think also with spotify) on the SHD the input automatically switches to LAN. So there has to be a code for this somewhere. Maybe it is not in a plugin but in the core of volumio? (I do not remember if this behaviour can be turned off by configuration.)

Ok this is getting freaky.  It did it again.    Flac file playing for 50 mins and suddenly the Studio just flicked from AEAS to USB.   Remote sitting on a table a foot away.    I was half dozing in the chair.

What gives?

I’m not sure, I have never used it.   I will try and find it.

My Studio is less than 12 months old so whatever a new unit came with then.

As I said I only have one cable attached to the Studio and that is the AES.

Well than maybe try a little workaround.
Just disable all other inputs over the SHD app where you can configure Routing and outputs.
Somewhere in the top menu there is an option for that.

There have been a couple of Volumio updates in the last 12 months but I very much doubt not having applied them would cause what you're experiencing. You could try all other inputs in the plugin as suggested above but I don't know why you're experiencing what you are. My SHD has never jumped to a different input without me asking it to. It's possible it's a hardware fault.

You could try disabling the WiFi connection on your SHD Stuido if it's active, bearing in mind that if you wanted to re-enable it you'd need to connect using an ethernet cable. You may never have enabled the WiFi connection to begin with though.

Maybe something in your home is sending infrared light that irritate the remote control receiver? (The remote is working with infrared, isn't it?) Do you have a smart phone with infrared sender? Or another remote control in use? Weren't there other sources like some kind of lights that could irritate?

Maybe you can try to block the infrared receiver from the SHD by setting something in front of it (a book or something) just to test if this helps. If yes, you have problems with other infrared sources. If not, the SHD is switching somehow itself.

There actually was a problem with remote control commands which occured from faulty code in the volumio plugin.

The SHD is separated in two devices. The DSP which has the infrared and display connected and the little streamer device which runs volumio and is connected to the DSP board by i2s for audio and by a serial port for getting information about the DSP status.

If you press a button on the remote the DSP board changes whatever you pressed.
After that it kind of informs the streamer/volumio about the change.
Than volumio can do stuff.
Also the streamer/volumio can send commands via serial connection to the DSP.
I think volume is handled by volumio. So the DSP board tells volumio volume up or down and volumio sends the command to the DSP board.

Not 100% sure but for example there was a problem when you press volume up and keep pressing it. Or when you press volume up/down very fast.
Sometimes this results in weird behaviour.

anyway. Connect your Studio to your LAN and update volumio. Consider it being a firmware update to your studio. ;-)

You don't have to login or anything. Just click thru the wizard and go to Settings -> System and update.

IMHO you should update all parts to be sure they work together well: Volumio, firmware, DSP.
