I've got an Audiotrak Prodigy HD2 - supported by snd_envy24ht - in my
desktop system and can confirm that recording doesn't work. While the
mixer shows the recording channels all I get is noise. On the playback
site the mixer also shows a lot non working channels:

Mixer vol      is currently set to  10:10
Mixer bass     is currently set to  50:50
Mixer treble   is currently set to  50:50
Mixer synth    is currently set to   0:0
Mixer pcm      is currently set to  50:50
Mixer speaker  is currently set to   0:0
Mixer line     is currently set to  75:75
Mixer mic      is currently set to   0:0
Mixer cd       is currently set to   0:0
Mixer mix      is currently set to   0:0

The only working channels are "vol" and "pcm". The equaliter channels
"treble" and "bass" have no effect. "synth", "speaker", "mic", "cd"
and "mix" result in: mixer: WRITE_MIXER: Device not configured

I'm happy to provide some more information, just send me the patches 
to test.
