[linux-audio-user] alsamixer and the audiophile 2496

[Eric Dantan Rzewnicki]

If i'm not mistaken the 2496 is an ice1712 based card. You should use
envy24control instead of alsamixer. Things will make much more sense. Be
sure to check out the command line options available to limit the number 
of channels it displays.

envy24control comes in the alsa-tools package.
