My Topping D90 is behaving perfectly with RoPieee - it goes into sleep mode when no music is playing.
However, I built a new RPi with RoPieee to connect to my Topping D50 and it stays on when no music is playing. It is connected via USB. When I stop playing music to it via Roon, it does go into sleep mode after a few seconds. However, it then starts up again almost immediately and stays on. This suggests that the USB interface is ‘live’ in some way and the Topping D50 thinks there is a digital audio signal being sent.
USB Auto Suspend is enabled in RoPieee. RoPieee version is 4.002 Stable.
Any ideas on how to troubleshoot this? It’s not a big deal as I can manually switch the Topping D50 DAC off when I’m not using it, but it would be nice to have a fully automatic system.
