I have no idea why is that the case, device is USB 2.0, even disabling

all other external USB devices and pluggin it into USB 3.0 doesn't help.

Nothing more in log.

Can "not enough bandwidth" or "usb_set_interface failed (-28)" message repoduced by using aplay or arecord with s24le/s16le at different rate instead of using pulseaudio ?
