I have a Pi4 4Gb with the Digi2 Pro. Audio out via SPDIF into Cambridge CXA81. When I first connected a monitor to it, as I did in the very beginning to load the HiFi Berry OS, I used HDMI out to a monitor. That resulted in zero audio coming out of the SPDIF. After much consternation I finally worked out to remove the HDMI and then presto, sound! But now when I hook up the HDMI there is no signal to the monitor. So my question is, can I have the best of both worlds?
