Because it never played any sound until I installed pulseaudio.
I tried with older kernel. The device was recognized at first, but didn't play any sound, even after creating correct asound.conf file. However, after I unplugged and plugged back the device, it is no longer recognized on any USB port. Also, with old kernel the CPU runs hot af - 60C+.
Below is dmesg log:
