When I first used a Topping E30 with piCorePlayer the DAC wouldn't go into standby. Adding a udev rule
fixed this and then the DAC entered standby when the piCoreplayer was powered off in LMS and came out of standby when the player was powered on.
I am trying out Volumio at the moment via the UPNP/DLNA plugin and when I add the the same udev rule the DAC enters standby a couple of seconds after playback stops and wakes up when playback begins sometimes missing the first notes of the track. Powering the player on or off in LMS has no effect.
Does anyone know what this udev rule does and is there a way to stop the player entering standby so soon after playback stops. I have seen udev rules for USB involving autosuspend with a delay but I have no idea how that is used either.
