I looked briefly in the kmix code. There are few places that could be
checked, but this will require enable debugging in the code (compiling etc)

But based on your input, this
http://www.linux-hardware-guide.com/2014-08-26-creative-sound-blaster-audigy-rx-sb1550-7-1-sound-sound-card-pcie
and this
http://alsa.opensrc.org/Emu10k1
https://wiki.debian.org/snd-emu10k1

I think you need at least custom setup to the driver (and perhaps newer
kernel version). This way the chance for the driver reporting usable setup
is higher.


I think you have to solve this and come back. Perhaps alsamixer can resolve
some of the reported features better than kmix, which does not mean that
what is reported is correct.

I see there is a lot of information on the web regarding your card. I am not
an expert in alsa, but I would look first in this direction. Try at least
setting up your device values properly.

I have for example

## ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-hda-intel
alias snd-card-1 snd-usb-audio

## module options should go here
options snd-hda-intel index=0 model=ref enable_msi=1 enable=0,1
