Description Of Issue
I’ve got a 16 channel firewire mixer as my default sound device under MacOS. All of my Mac OS generated sounds come through on the grouped stereo channel pair 15/16, however Roon only wants to send to channels 1/2 and I can’t see where to change this in Roon. Is this channel allocation configurable and if so, how.
Can you give procedural mixing a try and see if that helps with this? You can access Procedural EQ in the DSP Menu, under Add Filter -> Procedural EQ -> Add Operation -> Mix. Are you able to set your output to channel 15/16 there?
Thanks for sharing that link @BlackJack! @Craig_Joyce - I just double checked with the hardware team and this is indeed still a feature request. Roon currently only supports a maximum of 8 channels at this time.
For you to be able to use audio channels higher than 8 in your setup, you will need to re-map the channels via a 3rd party app. I can’t recommend any specific apps that accomplish this aspect, but there should be a few that do (or you can ask for the community recommendations in #roon)
