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. Takashi
I've compiled a kernel from git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git uname -a is "Linux meschi-Precision-WorkStation-T5500 5.10.0-rc7-next-20201208 #1 SMP PREEMPT Tue Dec 8 12:28:39 CET 2020 x86_64 x86_64 x86_64 GNU/Linux" The problem is still there. Is it possible to fallback to explicit feedback mode for the device from user space? I'd like to learn more about these feedback modes, is there a place where this is explained? I'm curious how this device is working on another machine. I'm not quite proficient with the alsa kernel subsystem to debug this myself, but I would be happy to test patches and learn along the way if somebody is interested in debugging this.
