snd-bebob : from kernel 4.13 to 5.3.19 and .20

Hi there,

I wrote 1st this here: 
https://github.com/takaswie/snd-firewire-improve/issues/25

But I think it was the bad place, sorry for that.

I think this ML is better?

My problem in one line:

I upgraded my Ubuntu Disco (kernel 4.13) to Ubuntu Eoan (kernel 5.3.19)
and I can report my SaffireLE / Firewire doesnt work anymore, snd-bebob reports "discontinuity of CIP" on dmesg...


At startup it lights green ok, but no sound is playable, then the
lights turn orange (like it is when it's not working), I hear a "relay
sound" (a electric clic of a relay), then, the Saffire LE disapears from the sound menu in Ubuntu sound menu.

I can see this in dmesg:

I tried update the kernel with eoan-proposed I know run 5.3.20 and I
have the same problem (the trace above is made with 5.3.20.

First, I hope I report this the best way, really not sure here.

If not, please tell me what to bring (files? logs?) and where (on this
list? elsewhere?).

I have spare time to investigate anything that could help here.


Thanks!
