Description of Issue
I’m hoping to save power by allowing Windows to go to sleep when not playing music. Windows is dedicated to hosting Roon Core and goes to sleep without issue but upon sending wake-on-lan packet to wake up machine, Roon displays no Audio Devices.
I’ve read about the Realtek HDMI audio driver issue and have tried updating, disabling Realtek audio device and uninstalling driver. No change.
If I remote to the typically headless Windows machine or with a monitor and keyboard attached and access the machine audio devices reappear as normal.
How can I get audio devices to appear after resuming from sleep?
Sadly, I get the same behavior with the Windows HDMI driver installed but disabled. I also tried disabling the Intel display audio driver.
I reboot after each disablement with sleep set to 3 mins. I wake with WOL utility. Once I access the server console via VNC, the audio devices ‘wake’ and resume as normal. Of course, I’d like it to no require accessing via VNC or other Remote Desktop utility.
I appreciate your help and effort so much. Thanks for trying
Since it looke like the WOL from sleep is not properly enabling the Roon audio devices, could you please check “Energy Efficient Ethernet” settings to see if that helps or “Fast Startup” in Power Options?
I’ve tried EEE on and off, no change. My Windows machine doesn’t appear to have the option to select Fast Startup enabled or disabled, the option simply doesn’t appear where the link refers. The setting is missing because I’ve disabled hibernation as I don’t wish to have the system hibernate.
WOL works fine to wake Windows, I don’t have a USB device connected, only Ethernet and power.
I’d just like to add that this issue has been bugging me for ages.
My PC wakes from sleep via a scheduled remote signal from Logitech harmony hub to USB flirc device connected to PC (so is detected as a keyboard wake event I believe). Roon client connects fine but no audio devices are detected. The moment I connect to the PC via VNC, the audio device(a raspberry pi endpoint) appears.
