What exactlty you would like to see? My problem is shown on the picture, the KMix panel shows the wrong PCM channel: capture instead of playback.

I have this exact card: https://ipon.hu/webshop/product/creative_sound_blaster_audigy_rx/530747

root@Csabi:~# lspci | grep Audio
01:00.1 Audio device: NVIDIA Corporation GK208 HDMI/DP Audio Controller (rev a1)

The SB card does not appear like this. I do not use this at all and it does not appears if i hit F6 in alsamixer.

root@Csabi:~# lspci | grep audio
06:00.0 Multimedia audio controller: Creative Labs SB0400 Audigy2 Value

With small "a" the SB card appears but my card is not an Audigy 2.

root@Csabi:~# cat /proc/asound/cards
 0 [Audigy2        ]: Audigy2 - SB Audigy 2 Value [Unknown]
                      SB Audigy 2 Value [Unknown] (rev.0, serial:0x10241102) at 0xaf00, irq 18

ALSA does not recognize the Rx card?

I don't understand. How this helps me, there is no information in this article about the Audigy Rx false recognition as Audigy 2. The soundcoure module is exists at my machine.

However a quick search shows that other people has this problem too:
But i have no problem with the sound or the MIDI, everything works fine, it's just an erroneous channel show in KMix.
This article says it needs additional firmware: http://www.linux-hardware-guide.com/in/2014-08-26-creative-sound-blaster-audigy-rx-sb1550-7-1-sound-sound-card-pcieShould i install the Rx firmware? I installed alsa-firmware-loaders, but i have no firmware to the Rx.
