The Behringer device now needs an option for it's kernel module (Alsa driver). Does anybody how can that be achieved automatically when you connect it? It needs an option right now, but the patch that enable the quirks by default has already been submitted and soon will be included in the mainline,...

Dear all, just to report the happy ending of the story. I have tested as requested by Takashi the card on the following cases: (1) x86_64 , 5.18.6 and 5.19-rc without quirks (2) Arm64 , 5.18.6 and 5.19-rc without quirks (3) x86_64 , 5.18.6 and 5.19-rc with quirks (4) Arm64 , 5.18.6 and 5.19-rc with ...

Having said all that, if this revision still works without any problems whatsoever in MacOS (which I doubt ) it might well be a Linux driver problem. If I were B. I wouldn't bother looking into the Linux problem if it indeed works flawlessly in MacOS. We should avoid confusion and state things clea...

Dear all, after several patches tried with no success, I managed to get in contact with  Behringer folks but I got this reply: --- Product:  Behringer UMC404HD  Thank you for your patience whilst this matter is being looked into. My colleague Nicolas is currently out of the office so I am following ...

Edit: I found the bug report again and uploaded this to bugzilla.

Great, thank you bluzee!

Hello Linuxmusician01, A developer asked for the output of alsa-info on both non-working ( bcdDevice = 1.35 ) and working ( bcdDevice = 1.12) cases. I am preparing the non-working cases, could you execute it for non the working case and upload here the log for working device? He said to just execute...

Hello Bluzee,

thank you for your support, however I managed to get in touch with them.
I found that when I registered the product they sent me a ticket so I can interact with them using just mail.

If they answer me something useful, I'll report here.

Have you heard anything back from Behringer? No, because Music Tribe gives me a headache.... it is slow and bloated, honestly I gave up during the registration for exhaustion. If you have a working account maybe you can report what we are discussing there. Maybe they can shed light on something use...

Did just that. Am listening to white noise as I'm writing this. Weird, isn't it? Ohh, I suspected! So there is something that is changed in the device behavior that makes it still a standard-compilant usb audio class 2 device but does not play nice with snd_usb_audio driver in both standard and imp...

However, could be one and the same problem. What I mean is: if one suppresses a valid error message then the actual (hardware) problem remains. This might be why you got rid of the error message whilst the audio stutter remained. Yes, I it could be either way. The delay addition does not suppress t...

I have filed a bug for this at:
https://bugzilla.kernel.org/show_bug.cgi?id=215934

feel free to register and add to the CC list. If more users are concerned maybe gets higher priority.
Moreover add comments to report additional user experiences with the device can be useful too.

Sorry if I was unclear; loading snd_usb_audio with implicit_fb=1 makes everything silent for my device as well... Now I wonder what version of the device they were running, odd that it would work for their device but not mine! Sorry, my fault, it was the UMC202HD not the UMC204HD, as reported in th...

Considering that behringer devices are not firmware-upgradeable by users they could increase just for firmware upgrades. Having said that, it is ...

Thanks. I tried that on mine. With one speaker attached. Been playing for a few seconds now. I hear no stuttering in the white noise. Cool, if your device is bcdDevice=1.12 I think that will work fine. No one lamented problems until 1.35. Anyway, when you test with speaker-test please remain listen...

Thanks Linuxmusician01 for your comment. Actually, when you rebuild a kernel from the source, you have to configure it and decide which module to build (I always opt for modules .ko files on disk for sound). They are installed per-kernel-version in folder /lib/modules and loaded from there (I always...
