Enable Audio output on HDMI-1

Help and Support Help
1

Hello, first sorry for my Google Translate English.

I use Volumio on a Raspberry 4 in which I also use OSMC with another SD and for specific needs when I use OSMC I have the “HDMI-0” output connected to the TV (for the video) and the “HDMI-1” output to the AVR (for the audio).

When I switch to volumio I usually use a USB DAC to use my HiFi amplifier but I would like to have the option to also use the HDMI1 output.

Currently when I select the HDMI output in volumio nothing happens, that is, no audio comes out through HDMI-1 to my AVR, any help would be welcome.

No one knows how to guide me in the right direction or at least tell me if volumio is at least capable of outputting the audio through HDMI-1 and not through HDMI-0???

Given that in this time no one has answered, am I to understand that it is impossible for volumio to do something so easy?
