KMix is an interface to alsa, so very probably alsa is not recognizing it or
reporting it correctly.
You did not provide any information about kernel or OS. Are you not using
pulse audio?
On the alsa page there are some instruction how to configure the devices
properly, so that you have consistent mapping. Example

       username@hostname# pico /etc/modules.conf
       
       # OSS/Free portion - card #1
       alias sound-slot-0 snd-card-0
       alias sound-service-0-0 snd-mixer-oss
       alias sound-service-0-1 snd-seq-oss
       alias sound-service-0-3 snd-pcm-oss
       alias sound-service-0-8 snd-seq-oss
       alias sound-service-0-12 snd-pcm-oss
       
       # OSS/Free portion - card #2 (cmipci)
       alias sound-slot-1 snd-card-1
       alias sound-service-1-0 snd-mixer-oss
       alias sound-service-1-3 snd-pcm-oss
       alias sound-service-1-12 snd-pcm-oss

Again, if your card is not supported by ALSA ... even if you see it somehow
correct in alsamixer, does not mean it would work without issues. Output of
following commands could be of interest though and ask ALSA if your card is
fully supported and how it can be configured based on the chip you have

 uname -a

 lsmod | grep snd

 amixer
 amixer -c 0
 amixer -c 1

It could be something in kmix, but I doubt it.
