I have volumio 3 running on a Pi Zero and just switched from an SMSL DAC to output over HDMI, using an HDMI audio extractor to extract the audio, and also have the extractor connected over HMDI to my TV. The TV is, however, it is not showing the HDMI interface, but it displays the TTY1 login terminal instead. Possibly I could switch to another TTY using a keyboard (which I haven’t connected), but I would rather have the HDMI output use the right TTY. What do I need to modify for this to happen?
You need to install the Touch Display plugin. Otherwise it will be nothing more than the terminal.
