just quickly verify that my changes to config are correct
for context, someone asked me to implement https://github.com/3ll3d00d/ezbeq/issues/66 which I've done so now just doing some quick tests to check
I can do it using arecord/aplay, it's just a bit slower/fiddly

I am not sure I understand. If you are just trying to analyze REW output via aloop, REW runs fine with a single aloop.
Hi
You need two loopback pairs so you will have:
rew->loopback(0,0)->loopback(0,1)->Input Camilladsp (what you want Camilladsp to do) ouputcamilladsp->loopback(1,0)->Loopback(0,1)->input REW
The loopback device is actually 2 loopbacks from (0,0) to (0,1) and a second loopback ( 0,1) to (0,0) if that makes sense?
In your setup it is (10,0) and (10,1)

Right, I did just plain loopback, no DSP inserted. I just wanted to show that REW works fine with snd-aloop devices, like any other alsa device.
Yes I use single device aloop at other times so I am using 2 aloop pairs exactly as @Henckel suggests, rew doesn't appear to allow selection of specific subdevices so I am not sure exactly what it is doing but my guess is some feedback loop. Hence thought of asking here to see if anyone has such a thing working before I post on avnirvana
Do you really need subdevices selection? See my example - loopback works fine, just select the corresponding card->device (not subdevice). I have a few loopback devices and all are available in REW:
Also, newer REW supports alsa PCM devices, allowing you to define any device in your .asoundrc and use it in REW. Those devices are prefixed with PCM:
no you're right, the bit I was missing was creating multiple aloop devices. Thanks for the tip, I'll try this out.
in case anyone is interested, there's an initial release of this linked from https://github.com/3ll3d00d/ezbeq/issues/66#issuecomment-1558108317 . I don't use camilladsp myself so I implemented it using some assumptions about pipeline layout that perhaps don't hold in real life. If anyone wants to comment or suggest changes then feel free to add to that issue or create new ones.
