[SOLVED] More than 1 audio output simultaneously

[Tim Curtis]

Seen that. I still want to know what the OP's use case is.

Just easier when using the the MoOde box in various ways, I sometimes use the XLR outputs on the HiFiBerry hat, other times I might be streaming via USB or even sending audio via HDMI. Having the ability to send to all outputs at once would be very handy as there'd be no configuration changes needed.
Alternately, the ability to have "presets" that from the press of a button could switch outputs without having to go into the config would be an awesome addition to MoOde. The ability to store different settings that can be recalled from the main screen or something. The config screens are pretty intimidating for users, and even for myself if I don't look at them very often I forget what each setting does!

Yes that would be fantastic :-) and if it could be done I'd definitely have it on the TODO list but currently there are limitations with the Raspberry Pi hardware and RaspiOS that prevent simultaneous audio output from HDMI, USB, I2S and Headphone, and there is no easy way to seemlessly switch between I2S and USB/HDMI.

Maybe something like a Pro-audio Interface would work?
