Steinberg UR22 Crackling and Clicks
Hi,
I am using a Steinberg UR22 audio interface. Since installing Ubuntu 20.04 on my workstation I have slight crackling in audio playback. It doesn't matter if the audio gets routed through pulse, jack or played straight to alsa. When running jack, the crackling is not showing any xruns. It's not possible to get any glitch-free playback in the system. The onboard intel audio works fine.
My system:
alsa info: alsa-project.org/db/?f=8b821b17a8c83fa5db866f34a5b4dfe74d640a32
Processor: Intel Xeon X5687
$ uname -a
Linux WorkStation-T5500 5.4.0-56-lowlatency #62-Ubuntu SMP PREEMPT Mon Nov 23 20:19:44 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
I have tried:
5.4.0-56-generic and -lowlatency
5.8.0-31-generic and -lowlatency
setting cpu governor to performance
using nouveau driver over nvidia
When playing a file with aplay like this:
systemctl --user stop pulseaudio.socket systemctl --user stop pulseaudio.service aplay -D plughw:CARD=UR22 ./test.wav
slight crackling can be heard every 5-10 seconds. It also appears, that the clicks heard are not always on both channels, sometimes the left stereo channel clicks, sometimes the right, sometimes both.
Plugging the Interface into different USB-ports doesn't help. The only external devices connected via USB are my mouse and my keyboard. On Wndows the same setup on the same machine works fine.
To make things even weirder, using the same audio interface on my Thinkpad x220 (Core i5-2540M) with ubuntu 20.04 and 5.4.0.56-lowlatency does not show this problem.
Running dmesg seems to show nothing audio driver related after:
[ 22.425520] usbcore: registered new interface driver snd-usb-audio
I have found a similar issue showcasing the problem on manjaro with a differend soundcard. Therefore I suspect the problem is caused by ALSA interacting with the hardware.
https://forum.manjaro.org/t/pops-clicks-on-audio-interface/40129
Here is another occurence on ubuntu on yet another audio interface.
https://askubuntu.com/questions/1256787/ubuntu-2004-novation-xiosynth-extern...
If I can supply more information I'm happy to help. I couldn't find a similar issue in this mailing list, so if this is already fixed I apologize in advance.

It's likely the issues with the implicit feedback.
The latest development tree (either linux-next tree or topic/usb-audio-refactoring branch of my sound.git tree) contains the improvements of the implicit feedback mode.

OK, so it's a different device than UR22C.
Try to pass the module option quirk_alias=04991509:0499172f to snd-usb-audio. This will make the device compatible with UR22C.

Hm, strange.
Please check the contents of /proc/asound/card*/stream* file. With the latest patches and the implicit feedback mode, you should see the lines like "Sync Endpoint: 0x...." and "Implicit Feedback Mode: yes".

OK, then it means that your device isn't compatible with UR22C. It has a different endpoint assignment.
What happens if you run this kernel without quirk_alias option? Is the implicit feedback still set?

OK, then it means that your device isn't compatible with UR22C. It has a different endpoint assignment.
What happens if you run this kernel without quirk_alias option? Is the implicit feedback still set?
Takashi
When running it without the quirk_alias option implicit feedback isn't set. I have appended the output at the end of this mail. Does this mean the card runs with explicit feedback, or with no feedback at all? I've tested this on other linux distros (Fedora 33, Kernel 5.8 and Ubuntu 14.04.6 LTS Kernel 4.4 or 4.6, don't remember exactly), problem still exists, so this doesn't look like a regression to me. Just to be sure: the last commits to pcm.c and implicit.h in my tree are from Nov. 23. Is that correct? I don't find the topic/usb-audio-refactoring branch on the public git mirrors of tiwai/sound, so not sure I'm running the latest changes.

It's a known side-effect of the implicit feedback mode, and the latest patchset I mentioned earlier addresses the issue.
Takashi
I'm already running the kernel built from the linux-next tree... I built next-20201208 from git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git Is there another patch set that I'm missing?
Hm, strange.
Please check the contents of /proc/asound/card*/stream* file. With the latest patches and the implicit feedback mode, you should see the lines like "Sync Endpoint: 0x...." and "Implicit Feedback Mode: yes".
Takashi

Takashi
When running it without the quirk_alias option implicit feedback isn't set.
Then try to pass implicit_fb=1 option to snd-usb-audio module. It's a new option that was added recently.

Nice, that did the trick. there was a small glitch on first playback but I can not reproduce it now. Playback seems glitch-free now. I will test it with pulseaudio in the gui if I can. It's not quite easy to test, because the system locks up after a while with the new kernel and gnome 3. I will also test concurrent playback and recording, too. Thank you very much, that was a huge help!

Good to hear. If the implicit_fb option works, we can add a static quirk table entry easily. Just add IMPLICIT_FB_GENERIC_DEV() with the device ID to playback_implicit_fb_quirks[] table in sound/usb/implicit.c.

Still having problems with the nouveau driver, so i couldn't thest this with pulseaudio. Recording with arecord works parallel to playing back with aplay. so here is my patch for implicit.c

OK, I'll cook up the proper patch and submit for 5.11 merge.
