Behringer UMC404HD stuttering / audio gaps

Post by greengardener »

Greetings!

I just bought a UMC404HD. I did some research before buying to make sure it was well supported under linux. Most posts say its working great. So i've plugged mine in expecting things to just work but that has not been the case.

I plugged it all in and found that it stutters every second like a scratched cd would. I've played around with the sample rate and settings but have not been able to fix it.

- There are no Xruns.
- There are not error entries in syslog or jack log.
- The CPU is running around 5% and does not spike
- I'm dual booting and this device works flawlessly in windows. I've also tried on MacOS Monterey and also works fine.
- Tried different USB cables
- I've tried standard and low-latency kernels (5.4.0-107-lowlatency)
- I'm running Mint 20.03 but have also tried Ubuntu LTS 20.04 and Ubuntu Studio.

Here is some information on the device:

Code: Select all

[    2.313692] usb 1-1: new high-speed USB device number 2 using xhci_hcd
[    2.441209] usb 1-1: New USB device found, idVendor=1397, idProduct=0509, bcdDevice= 1.35
[    2.441210] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[    2.441211] usb 1-1: Product: UMC404HD 192k
[    2.441211] usb 1-1: Manufacturer: BEHRINGER
Im seeing the following entries in dmesg which has me concerned.

Code: Select all

[    8.015105] usb 1-1: clock source 41 is not valid, cannot use
[    8.016412] usb 1-1: clock source 41 is not valid, cannot use
[    8.017768] usb 1-1: clock source 41 is not valid, cannot use

Has anyone seen something similar? Am I in the correct forum? Is there any further information I should provide?

Thanks!

I've got the same device. Works just fine. What audio application are you using that has the audio stutter? How did you start Jack Audio or didn't you yet?

I also have never had an issue with UMC404HD. Used it in various distros on various hardware even an Android box.

What motherboard and cpu do you have? Are you plugging into USB 2, 3, C? Any USB hubs involved?

I started with jackd and qjackctl because I used that for my previous interface and everything looked like it detected at first plug in. I have a Lenova Ideapad slim 3 (laptop) which supports USB2.0 and USB3.0 A types. I have tested on both ports and not using any USB hubs in between.

CPU is Intel© Core™ i7-1065G7 CPU @ 1.30GHz × 4

My test now uses 'speaker-test' with a tone using the default driver "pulseaudio"

I have plugged into another Ubuntu laptop and experiencing the same error message and audio skips. I've also tried a fresh OS reinstall.

Mine identifies slightly differently...

Code: Select all

Apr 11 23:06:29 TECRA kernel: usb 1-7: new high-speed USB device number 2 using ehci-pci
Apr 11 23:06:29 TECRA kernel: usb 1-7: New USB device found, idVendor=1397, idProduct=0509, bcdDevice= 1.12
Apr 11 23:06:29 TECRA kernel: usb 1-7: New USB device strings: Mfr=1, Product=3, SerialNumber=0
Apr 11 23:06:29 TECRA kernel: usb 1-7: Product: UMC404HD 192k
Apr 11 23:06:29 TECRA kernel: usb 1-7: Manufacturer: BEHRINGER
Hopefully they haven't changed the device to something that requires quirks to work properly.

You're using PulseAudio and Jack at the same time. How are you starting Jack? I use this audio device with very old hardware: no problems. I'll bet you a million dollars it a config prob of some sorts, if the interface ain't broken. But you say it works just fine in Windows so that ain't it. So: what command do you use to start Jack? Do it with a minimal command like this:

Code: Select all

jackd -d alsa --device hw:1
Or try to test it once without Jack just to know if it works w/ Linux.

P.S. Don't use the program speaker-test. It crashes on my PC. Just play some music with Audacity or something. Make sure you select the correct driver (i.e. Jack) and restart Audacity.

I have reformatted and installed Mint 20.3.

I ran jackd from the command line (as per the above post) test audio through Ardour5 with jack selected. The issue persists.

I disconnected the 404 and then connected my old M-Audio Fast track and tried the test again. No problems with audio.

I found this tidbit regarding the different bcdDevice value identified:
The bcdDevice has the same format than the bcdUSB and is used to provide a device version number. This value is assigned by the developer.
It could be a new hardware revision

Can someone with a working UMC404HD provide me with their output from the following command?

Code: Select all

~$ lsusb -d 1397: -v
Id like to compare it with mine:

It spit out over 900 lines so I'm attaching a TXT file.

Thanks bluzee. There are certainly a few differences including a firmware upgrade interface on yours.

I really am hoping its a configuration problem but not sure where I could look next. :?:

Did you try fully switching off your computer and start Mint i.e. a cold boot? On some hard to solve issues it may help to pinpoint the cause.
So, fully switch off, remove if possible the battery if it a laptop, wait 10 minutes or so (to be sure that internal memory is 100% cleared) and then start the PC.

Output from my Behringer 404HD by dmesg:

Code: Select all

$ dmesg
[ 1708.252994] usb 1-1.2: USB disconnect, device number 5
[ 1711.035801] usb 1-1.2: new high-speed USB device number 6 using ehci-pci
[ 1711.144791] usb 1-1.2: New USB device found, idVendor=1397, idProduct=0509, bcdDevice= 1.12
[ 1711.144794] usb 1-1.2: New USB device strings: Mfr=1, Product=3, SerialNumber=0
[ 1711.144797] usb 1-1.2: Product: UMC404HD 192k
[ 1711.144799] usb 1-1.2: Manufacturer: BEHRINGER
Output of the command that spits out 900 lines ( ;)) is in attached text file.

Could you tell what the difference is between your lsusb and our lsusb output? Would be crazy if Behringer changed their hardware so that it accidentally doesn't work with ALSA (Linux) anymore. In the worst case one must file a bug report or something to the ALSA developers so they can update the kernel module for this device.

If I'm not mistaken then one can use the 404 also as some sort of mixer if it is simply powered on (without a computer attached!). Do you have said problems then too? I don't think so since it works fine in Windows you say. If so: return the device to the store! Does powering it with the adapter help? Or not using the power adapter?

Good luck trouble shooting, I am very interested in knowing if the 404 still does or does not work with Linux nowadays! Keep us informed. :?:

Not sure if you have tried this yet, but make sure Pulseaudio is completely shutdown and out of the way then start Jack and see if it makes any difference.

On my machine I have the pulseaudio module for jack disabled in default.pa and in pavucontrol configuration I set the profile for the UMC404 to OFF. I used to also start jack with pasuspender but that may be overkill. When i first got my 404 pulseaudio did not configure it at all properly but it always worked perfectly with Jack. I believe in Mint 20.3 pulse now sees it as a 4 in 4 out interface, but I still prefer to have Pulseaudio out of the picture.

On my laptop with AVL-MX I completely deleted pulseaudio.

Even though there are differences in the lsusb output, I only have enough understanding to get myself in trouble :D
It does look different (an extra configuration and an upgrade interface?) but I'm not sure what that all means.

I did some more extensive testing on my device in Windows and it turns out I'm seeing the same issue. I'm going to return the device.

Stop the press!

Before you return it could you try this (see Reddit): load the snd-usb-audio kernel module with the implicit_fb=1 option. You can do it by creating a file in the directory:

Code: Select all

/etc/modprobe.d/
(you can give it any name, but it has to end with .conf) with the following content:

Code: Select all

options snd_usb_audio implicit_fb=1
then reboot your system.
