Yamaha DM3 is an acessable pro digital mixer that has optional dante transport and does 18x18 at 96khz by 32bit on USB. It sounds amazing, it's a beast and works driver free on 14.2.
It might be worth the cost just to get a 16x16 usb/dante bridge without paying the yearly driver ransom to audiante.
I got it to record and play back in multichannel with jack and virtual_oss, but I still need a bit of help getting system audio to route to it.
Here's the process:
boot takes a minute then:
the midi surface transmit works when enabled from the settings-> midi -> enable control, program change then
cat /dev/umidi0.0
#then wiggle the faders because .. funny - see dirtyriggers' filter for ops
-or-
et 96khz sample rate to match the DM's max in settings-> clockrate 96khz
# do both or jackd will error out
#and -r for jackd
jackd -d oss -r 96000 -C /dev/dsp3 -P /dev/dsp3
Get https://github.com/jackaudio/jack-example-tools/ from pkg or whereever
Make a sad test tone, creates audio (annoying stereo tones) on the dm3
jack_simple_client
look at settings -> patch, it will show the channel lit on input:USB 1,2 when signals are hitting it, it's really handy to see the signal while learning to route the board's actual mixer inputs
Patch them to convenient channels (9-10?)
enumerate ports:
now some recording
Activate a test burst tone from oscillator, patch it to a mix bus and out usb1,2 . This works for multichannel!!!!!, just add all the system:capture[.] devices to jack_rec target
now how do I use this? mplayer refuses to open dsp3:
installing virtual_oss from pkg
Now for the ask:
How do i get other normal system audio ( firefix/chome whatever)to see that virtual_oss port?
can set the -f /dev/dsp4 but the kernel can' set hw.snd.default_unit to 4 =(

hw.snd.vpc_0db: 45 -> 11 <<-------- this should be terrible, but no effect
this default is very wrong in base anyway as it clips instantly, i think a quick hard knee compression could be an ok default
# mixer isn't playing nice eirther

How do i get other normal system audio ( firefix/chome whatever)to see that virtual_oss port?
can set the -f /dev/dsp4 but the kernel can' set hw.snd.default_unit to 4 =(
