The ID of this device is 17ef:3053. When first listening to this device, the audio was noisy and the audio quality was not that well. I am using fedora 31 stable. Inside the dmesg I found the following line: [ 31.659316] usb 1-4.4: 2:1: cannot get freq at ep 0x1 I have found the following suggestion online to this error: https://www.raspberrypi.org/forums/viewtopic.php?p=1442317#p1442317 I have added the following command to /etc/default/grub at GRUB_CMDLINE_LINUX and created a new grub.cfg: snd-usb-audio.quirk_alias=17ef3053:047f02f7 After reboot, the audio quality was fine. Nevertheless I have noticed that the volume control is still not fine. The volume is really quiet until about % of the scale and over this, the volume jumps up. I am attaching the dmesg and hwinfo output as txt. -- You are receiving this mail because: You are watching the assignee of the bug.
