	I would have tried to explicitly upgrade it, but the thing is I do not
know how to do that – I am more used with Debian tools and I get
confused with DNF.

	It is:

$ cat /proc/asound/cards
 0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xf7310000 irq 29
 1 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xf7080000 irq 17
 2 [M2496          ]: ICE1712 - M Audio Audiophile 24/96
                      M Audio Audiophile 24/96 at 0xc040, irq 19
 3 [U0x46d0x81d    ]: USB-Audio - USB Device 0x46d:0x81d
                      USB Device 0x46d:0x81d at usb-0000:00:14.0-13.2,
high speed

	I am using the M Audio soundcard.

	Here is the result:
