Volumio 3 - ACPI

I have a Volumio 3 installation on an SBC X12STN-C Supermicro. I noticed that the computer does not go to sleep when I do not play anything, despite the fact that the Bios mode is S3. Does Volumio support energy management? I would like to keep Volumio to sleep when nothing is being played, and to wake up when we try to use the Volumio application on a smartphone or on a PC access via the website.
Thank you in advance for your help.

No, this is not supported and there are no plans to develop such x86 platform-specific features in Volumio’s core.

I would suggest this option in the “sleep mode” functionality. The streamer then gains full automation of operation and comfort for the user. I’d be very thankful.

Sorry, no plans
