Hi List,
I have
an updated Manjaro system and two RME Fireface 800 8-output-channel
devices, both of which work well. I would like to create a 16-channel
virtual device for playback, but I am having quite a bit of difficulty. I
have tried many things, but the closest I have come to success seems to be
with the following .asoundrc, which allows me to use either ff800_1 or
ff800_2 to playback sound with portaudio, but ff800x2 (the intended
16-channel virtual device) does not show up and thus is not accessible.
This config file was adapted with minimal edits from post #19 at
https://bbs.archlinux.org/viewtopic.php?id9370 which claims to be a
working example (although as posted it duplicated 2 audio channels out to 4
hardware channels across 2 devices).
Any insights into what I am doing wrong are greatly
appreciated.
