Just wanted to report back that I've been running tiwai/for-next
including this patch and others for about a week now, and everything
works great on a Focusrite Saffire 26; it's more stable than ffado with
JACK and PipeWire also works. Thank you for finally fixing this!
One thing: I've noticed that on these interfaces, each
transmitter/receiver gets a different PCM device (e.g. on this one, two
capture PCM devices and one playback PCM device). I assume that
bonding/simultaneous use is left for userspace to do, and that it can be
done sample-accurately, right? This might be a little annoying for JACK,
though not an issue for PipeWire as far as I know. With libffado on
these DICE devices, the library takes care of bonding all the tx/rx
groups into one set of channels.
