I've not really played with stereo tool but it seems like it outputs at
192khz (if I understand the conversation thread).
So on the output you'd need the sound card to be set to 192khz across
the board. The problem being the max Riv supports is 48khz.
You'd save yourself a lot of headaches by having two sound cards. Have
Riv output straight to the sound card (ALSA) and then run a line out
from that to line in on the other card.
JACK then runs the other card for stereo tool purposes?

Hello,
I'm trying to run RD with Jack on my laptop. I need to run Jack at
192khz sampling rate for FM processing.
RD doesn't seem to want to play ball. When I start caed -d, it
complains of a sample rate mismatch and all the music plays at the
wrong speed.
What am I doing wrong here?
I have made a little progress with this...
I have found I can run jackd at 192khz and then use this asound.conf
to create a 'virtual' interface from jack:
pcm.rawjack {
type jack
playback_ports {
0 system:playback_1
1 system:playback_2
}
capture_ports {
0 system:capture_1
1 system:capture_2
}
}
pcm.rd0 {
type plug
slave { pcm "rawjack" }
}
ctl.rd0 {
type hw
card 0
}
This works ok ish:

But I have two issues... It's complaining about no control device for
rd0 (but works anyway) and it's still connecting to jack as rd1.
Is there anyway to make it not try to do jack other than recompiling
it without jack support?
