Issues with Behringer UMC202HD

Hello,

I'm having some troubles with my external audio drive(Behringer UMC202HD): if I disconnect it and then I connect it again, it doesn't work anymore(the computer uses the laptop's audio output). Since I'm using i3wm, I have to end the session(Mod + Shift + E) and then log in again. At the moment, I have no clue on how to solve this...

While inspecting the journal (journalctl -b) I found those line about connection/disconnection of the drive, hope it is useful:

Re: Issues with Behringer UMC202HD

There are some behringer fixes in current kernels, while I'm not sure they are in 5.18 but fairly certain they will be in 5.19.

FWIW something you can try now is loading/reloading snd-usb-audio with implicit_fb explicitly enabled, disconnect the device and do.  i.e.

sudo modprobe -r snd-usb-audio
sudo modprobe snd-usb-audio implicit_fb=1

If this works you can make the flag persistent in /etc/modprobe.d/implicitusbfb.conf

options snd-usb-audio implicit_fb=1

Re: Issues with Behringer UMC202HD

Thanks for your reply. I have done what you suggested but it didn't work :-/
I'll wait for the next kernel update and see if it does fix the issue.
